ANALOG INPUT
One analog input is available on signal MM PIN 33, it has been connected through a specific
circuitery that allows to acquire the analog signal directly or divided by 4.
OPTOCOUPLED DIGITAL INPUT LINES
The card features 16 NPN/PNP inputs connected to two quick release screw terminal connectors that
are directly acquired by 16 I/O lines of 40 pins socket through a galvanically isolated interface.
These lines are visualized by specific LEDs and have been selected to be able to take advantage
completely of eventual grifo® Mini Module internal peripherals, in such case the inputs can generate
interrupts, be counted by hardware counters, etc.
Optocoupled inputs are supplied by a specific voltage called +Vopto generated on board by a specific
circuitery separated from +5 Vdc generation circuitery.
SERIAL COMMUNICATION
GMB HR168 features one AMP 4+4 connector (CN6) dedicated to serial communication.
By hardware it is possible to select the electric protocol, through a comfortable set of jumpers and
drivers to install.
In detail line can be not buffered (this means to connect signals MM PIN 9 and MM PIN 10 directly
to CN6) or buffered in current loop, RS 232, RS 422 or RS 485; in these last two cases also
abilitation and direction of line can be defined using signals MM PIN 17 or MM PIN 30.
In case a grifo® Mini Module is installed, protocols TTL and RS 232 are immedatly available.
Please remark that by default the board is provided without drivers, so any configuration must be
specified in the order.
For further information about serial communication please refer to paragraph: “CONNECTIONS”
and “SERIAL COMMUNICATION SELECTION”.
I2C BUS LINES
GMB HR168 is provided with one connector (CN8) dedicated to I2C BUS, connected to two signals
of the 40 pins socket, MM PIN 12 and MM PIN 13, each provided with a 4.7 kΩ pull-up.
This kind of interface allows to connect devices featuring the same communication standard, to
easily improve the system performances.
Connector has been designed to allow both external and internal connections and satisfy any need
of the user.
A wide set of software examples explains the management of most common I2C BUS peripherals like
A/D and D/A converters, display drivers, memories, temperature sensors, etc.
GMB HR168 can be ordered with a Real Time Clock provided with 256 bytes of SRAM already
installed (option .RTC), in such case the slave address A0H is already taken by this peripheral,
eventual third part hardware cannot use it, in addition a grifo® Mini Module provided with its own
Real Time Clock cannot be installed for the same reason.

MINI MODULE
By Mini Module it is meant the component installed in the 40 pins socket ZC1 that decides the
functionality of all board signals.
Such component is also in condition to take control of all on board resources and can be In-Circuit
programmale, e. g. using a boot loader on serial interface, like for grifo® Mini Modules.
GMB HR 168 has been designed to accept all 28 or 40 pins grifo® Mini Modules or any hardware
that can fit in a standard 40 pins 600 mils DIP socket.
For further information please refer to description of socket ZC1 in the chapter dedicated to
connectors and to chapter "PERIPHERAL DEVICES SOFTWARE DESCRIPTION".
Every combination GMB HR 168 + 28 or 40 pins grifo® Mini Module is a separated item on our
listing, in addition each grifo® Mini Module has specific features (e. g. different size of FLASH
memory, number of digital I/O signals, etc.), for this reason each combination is described by its own
manual.
If a combination GMB HR 168 + grifo® Mini Module has been ordered, it will be delivered already
installed, configured and ready for use.
I/O TTL SIGNALS
GMB HR168 features up to 5 digital I/O TTL signals of 40 pins socket connected to a specific AMP
4+4 connector (CN7).
In case a grifo® Mini Module or the optional Real Time Clock is installed, some of these features
become available on CN7: PWM line from CPU internal PCA to generate an analog signal, count
signal from CPU internal 16 bit Timer Counter, etc.
DIGITAL RELAYS OUTPUTS
The board is provided with 8 relays outputs 4 A, normally open, whose status is visualized by 8 LEDs.
Each line is driven directly by a signal of the 40 pins socket, buffered through a specific driver and
connected to a comfortable quick release screw terminal connector to easy interface to the field
signals.
In this casea grifo® Mini Module is installed, it is possible to take advantage of internal peripherals,
like PCAs, that allow to generate timings and developed funcitons.

POWER SUPPLY SECTION
GMB HR168 is provided with an efficent switching power supply section, that provides supply +5
Vdc voltage needed by logic and output circuits, in any condition of input load and voltage.
A second section is present and generates the rectified voltage +Vopto, allowing to use the
optocoupled inputs simply closing its contact with the respective common terminal.
This latter section requires a separated power source.
The board features components and circuits designed to reduce consumptions and to reduce noise
sensibility.
Remarkable is protection circuit based on TransZorb™ that avoids damages due to incorrect
voltages.
To supply optocouplers of galvanically isolated sections a voltage between 12÷24 Vdc is needed.
For further information please refer to chapter “ELECTRIC FEATURES” and paragraph “SUPPLY
VOLTAGES”.
TELECONTROL FIRMWARE
The Mini Module installed on GMB HR168 can be provided with a telecontrol firmware; such
firmwares allow to manage all the board resources through a set of commands to send to the serial
line.
Taking advantage of these firmwares make possible to use well developed commands that solve
fundamental problems of automation like impulse count, wave from generation, debounced input
acquisition, Real Time Clock managentent, etc.
For grifo® Mini Module, Master Slave communication mode is supported; this allows to remote
single modules also at great distance, to build a telecontrol network driven by a unique master unit
(PC, PLC, GPC®, etc.).
By now, some standard protocols like ALB x84 (ABACO® Link BUS) and MODBUS are available,
anyway new protocols can be developed on specific request of the customer.
Please contact grifo® for further information.

Possible Current Loop connections are two: 2 wires and 4 wires. These connections are shown in
figures 13÷15 where it is possible to see the voltage for VCL and the resistances for current limitation
(R). The supply voltage varies in compliance with the number of connected devices and voltage drop
on the connection cable.
The choice of the values for these components must be done cosidering that:
- circulation of a 20 mA current must be guaranteed;
- potential drop on each transmitter is about 2.35 V with a 20 mA current;
- potential drop on each receiver is about 2.52 V cwith a 20 mA current;
- in case of shortciruit each transmitter must dissipate at most 125 mW;
- in case of shortciruit each receiver must dissipate at most 90 mW.

INTERRUPTS
Interrupts management depends completely on hardware installed in ZC1, in fact it's this latter to
determine which signals are interrupts.
If a grifo® Mini Module is installed, several interrupt sources are available, depending on which
model is used. Please refer to specific manual for further information.
I/O CONNECTION
To prevent possible connecting problems between GMB HR168 and the external systems, the user
has to read carefully the previous paragraph information and he must follow these instrunctions:
- For RS 232, RS 422, RS 485, Current Loop and I2C BUSsignals the user must follow the standard
rules of each one of these protocols, I2C BUS signals are also provided with 4.7 kΩ pull up.
- For all TTL signals the user must follow the rules of this electric standard. The connected digital
signal must be always referred to card digital ground and if an electric insulation is necessary,
then an opto coupled interface must be connected. For TTL signals, the 0V level corresponds
to logic state 0, while 5V level corrisponds to logic state 1.
- The analog inputs (A/D Converter section) on CN7 is provided with filtering capacitors that
warrant more stability on the signal to acquire and lower the cut-off frequency. It is also
possible to connect a voltage divider that divides by 4 the signal amplitude.
- Optocoupled input signals can be configured as NPN or PNP through jumpers J1 and J2, these
jumpers must be moved together. In detail, if inputs are configured as NPN, positive voltage
is present on input pins (INx-1, INy-2) and ground is present on the common pins (COM1 and
COM2), while if the inputs are configured as PNP the situation is reversed, this means ground
on input pins and positive signal on common pins.
- Relays outputs must be connected directly to the load to drive (remote control switches, power
relays, etc.). Board contact is normally open and can bear 5 A up to 30 Vdc. To drive load with
different supplies, different COMMONS for the groups of relays are available.

POWER SUPPLY
GMB HR168 is provided with an efficent circuitery that solves in a comfortable and efficent way
the problem to supply the card in any condition of use.
Here follow the volages required by the card:
+V opto: Provides power supply to optocouplers of board input section; input voltage must be in
the range 9÷28 Vdc ± 5% or 9÷23Vac ± 5% and must be provided on connector CN5
through pins 1 and 2, connecting pin 2 to the positive terminal of external power supply
and pin 1 to its ground terminal, if it is direct voltage.
Vac, +Vdc pow, GND:
Provide power supply to control logic and to output section of
the board through the on board switching power supply; input voltage must be in the
range 10÷38Vdc ± 5% or 8÷23Vac ± 5% and must be provided though puns 3 and 4 of
CN5 (in case of Vdc, pin 4 must be connected to positive terminal). This allows to supply
the cards using standard devices of industrial sector like transfrmers, batteries, solar
cells, etc. If external loads must be supplied, a +5 Vdc voltage can be fetched from pins
1 and 7 of CN6, CN7 or pins 1 and 4 of CN8. Please remark that on board switching power
supply is provided with single diode rectifier, so in case of Vdc supply, all ground signals
(GND) of the card are at the same potential.
To warrant highest immunity against noise and so a correct working of the cards, it is essential that
these two voltages are galvanically isolated
In order to obtain this power supply EXPS-2 can be ordered.
This device performs galvanic isolation starting from mains power supply.
GMB HR168 features a TransZorb™-based protection circuit to avoid damages from incorrect
tensions and break-down of power supply section.
On board power supply is visualized through a LED on the bottom left corner.
Current available to supply external loads using +5 Vdc is less than:
1000 mA - current absorbed by GMB HR168 - current absorbed by hardware on ZC1
for example, in case of Mini Module GMM 5115:
1000 mA - 542 mA - 49 mA = 409 mA.

INPUTS CONFIGURATION AS NPN OR PNP
The 16 optocoupled inputs of GMB HR168 can be configured as NPN or PNP according to the
connection of jumpers J1 and J2.
Power supply of optocoupling sections is provided externally through connector CN5 (please refer
to paragraph "ELECTRIC FEATURES" and to paragraph of connector CN5 for further information);
such power supply is rectified by a specific circuitery that generates two voltages: +Vopto and GND
opto.
Connection of jumper J1 and J2 determines which of these two voltages will be present at common
pin of optocoupled inputs (pin 9 of CN1 and CN2, that is COM1 and COM2), while the other voltage
will be present at all other pins of CN1 and CN2.
This allows to close an optocoupled input simply by connecting it to its common pin.
Jumpers J1 and J2 always must be moved together at the same time.
They can be connected only both in position 1-2 or both in position 2-3.
If one of the above rules is not respected, GMB HR168 could be damaged, so it is suggested to move
jumpers J1 and J2 only when power supply is off.
As already printed in table of figure 33, connecting J1 and J2 in position 1-2 configures inputs as type
NPN, while connecting J1 and J2 in position 2-3 configures inputs as type PNP.
About polarity of pins COM1 and COM2: as type NPN COM1 and COM2 are connected to +Vopto,
while as type PNP COM1 and COM2 are connected to GND.
BACK UP
GMB HR168 can be ordered with an optional Real Time Clock already installed (option .RTC).
This component provides hours, minutes, seconds, dat, month and year and features a 256 bytes
SRAM.
On board is installed a Lithium battery to keep the time and the content of SRAM even when power
supply is off, if jumper J9 is connected. By default, jumper J9 is NOT connected.
For further information, please refer to paragraph "ELECTRIC FEATURES".
ANALOG INPUT
GMB HR168 features an interface for one analog input that can accept an input voltage in a variable
range according to connection of jumper J11: in position 1-2 the analog input signal is filtered, so
that its stability is increased, while when J11 is in position 2-3, also a voltage divider acts on the
signal, dividing its amplitude by 4.
As shown in figure 24, such analog interface is based on high precision passive components that are
selected during mounting phase to optimize signal acquisition.
Anyway, to compensate eventual tollerances and thermal drifts, the best thing is to make a software
calibration of the signal acquired, that is to calculate a correction coeffincent using a reference signal,
then to use such coefficent for successive analog signal acquisitions.
Examples developed for grifo® Mini Modules show some calibration techniques that the user can
modify according to the application's needs.
Please refer also to figure 4, if you are using a grifo® Mini Modules please refer to the combination
manual.

SERIAL COMMUNICATION SELECTION
Serial line of GMB HR168 can be buffered in RS 232, RS 422, RS 485, Current Loop or TTL.
By hardware can be selected which one of these electric standards is used, through jumpers
connection (as described in the previous tables) and drivers installation.
By software the serial line can be programmed to operate with all the standard physical protocols,
in fact the bits per character, parity, stop bits and baud rates can be decided by installing the opportune
hardware on socket ZC1. In the following paragraphs there are all the information on serial
communication configurations.
Some devices needed for RS 422, RS 485 and Current Loop configurations are not mounted on the
board in standard configuration; this is why each fist non-standard (non-RS 232) serial configuration
for line A must be always performed by grifo® technicians.

In point-to-point connections, signal DIR can be always kept low (trasnmitter always enabled),
while in multi-point connections transmitter must be enabled only when a transmission is
requested.

If using the RS 422 or RS 485 serial line, it is possible to connect the terminating and forcing
circuit on the line by using jumpers J3 and J4. This circuit must be always connected in case
of point-to-point connections, while in case of multi-point connections it must be connected
olny in the farest boards, that is on the edges of the commmunication line.
During a reset or a power on, signal DIR is at logic level high, so during these phases driver
RS 485 is in reception or transmission driver RS 422 is disabled, to avoid confilcts on line.
(**) In case of RS 422 or RS 485 communication, signal DIR can be selected according to the
connection of jumper J10:
J10 in position 1-2
J10 in position 2-3
->
->
DIR = MM PIN 17
DIR = MM PIN 30
This allows to use the resources of hardware installed on socket ZC1 the best way possible,
whithout having to use and I/O signal of CN4 for serial communication.
(#)
Serial line of hardware installed on socket ZC1 must be designed to connect signals MM PIN
9 and MM PIN 10 respectively to RS 232 RX and TX where "serial line in RS 232" is required
or TTL RX and TX (e. g., generated by a microcontroller on board UART) where "serial line
in TTL" is required

In the previous paragraphs are described the external registers addresses, while in this one there is
a specific description of registers meaning and function (please refer to I/O addresses table, for the
registers names and addresses values). For a more detailed description of the devices, please refer
to documentation of GMB HR168 + grifo® Mini Module combination. In the following paragraphs
the D7÷D0 and .0÷7 indications denote the eight bits of the combination used in I/O operations.
RELAYS OUTPUTS
Staus of 8 digital relays outputs is set through 8 signals of 40 pin socket ZC1.
Please remark that signal driving relay OUT D2 can be connected either to signal MM PIN 16 or to
signal MM PIN 30 according to the connection of jumper J10:
J10 conncted in 3-4
J10 connected in 4-5
->
->
OUT D2 driven by MM PIN 30
OUT D2 driven by MM PIN 16
When the signal of socket ZC1 is set to logic state low (logic 0), the corresponding output is actived
(relay contact is connected to its common pin), viceversa when the signal is set to logic state high
(logic 1) the corresponding output is deactived (relay open).
As previously said, LEDs LD1÷8 provide a visual indication of digital outputs status (LED ON =
output actived).

I2C BUS
Signals used are pin 2 of CN8 (SDA) and pin 3 of CN8 (SCL) as shown in figure 4, connected
respectively to signals MM PIN 12 and MM PIN 13 of socket ZC1.
Signals SDA and SCL are also provided with 4.7 kΩ pull up resistors.

OPTOCOUPLED INPUTS
Status of 16 digital optocoupled inputs can be acquired by software by reading the status of
corresponding singals of 40 pins socket, described in table of figure 4.
When NPN or PNP inputs are enabled, corresponding signals are at logic state low (logic 0),
viceversa when inputs are disabled a logic level high is acquired (logic 1).
As previously said, LEDs LD9÷24 give a visual indication of digital inputs status (LED ON means
input actived).
In detail, green LEDs (from LD9 to LD16), visualize optocoupled inputs from IN1-1 to IN8-1 of
group 1 and referring to common pin COM1, while yellow LEDs (from LD17 to LD24), visualize

RTC + SRAM
GMB HR168 can be ordered with an optional Real Time Clock + SRAM module already installed
(option .RTC).
The SRAM module, is provided with 256 bytes and the Real Time Clock which manages time (hours,
minutes, seconds) and date (day, month, year, day of the week).
Option is delivered with on board Lithium battery installed.
RTC section can also generate periodic interrupts whose period can be programmed by the user, so
it can be used to awaken CPU from low consumption working modes.
For software management of serial SRAM+RTC module, please refer to specific documentation or
to demo programs supplied with the card.
The user must realize a serial communication with I2C bus standard protocol, through two ZC1 zoket
signals.
The only necessary information is the electric connection:
DATA line (SDA)
CLOCK line (SCL)
->
->
MM PIN 12 P2.1 (input/output)
MM PIN 13 P2.0 (output)
Please remark that A0 of this component's slave address is bound to logic 0, so its slave address is
hexadecimal A0H.
Logic state 0 of line corresponds to low level logic state (= 0 V), while logic state 1 correspons to
high level logic state (= 5 V).
We also would want to remark that SDA and SCL lines are connected to a 4.7 KΩ pull-up resistor.
NOTE:
When using a GMB HR168 provided with optional Real Time Clock, it is not possible to install a
grifo® Mini Module with its own Real Time Clock on board, because they use the same slave address
and would conflict.

PCF8583
Whenever an alarm event occurs the alarm flag of the
control/status register is set. A timer alarm event will set
the alarm flag and an overflow condition of the timer will set
the timer flag. The open drain interrupt output is switched
on (active LOW) when the alarm or timer flag is set
(enabled). The flags remain set until directly reset by a
write operation.
FUNCTIONAL DESCRIPTION
The PCF8583 contains a 256 by 8-bit RAM with an 8-bit
auto-increment address register, an on-chip 32.768 kHz
oscillator circuit, a frequency divider, a serial two-line
bidirectional I2C-bus interface and a power-on reset circuit.
The first 16 bytes of the RAM (memory addresses
00 to 0F) are designed as addressable 8-bit parallel
special function registers. The first register (memory
address 00) is used as a control/status register.
The memory addresses 01 to 07 are used as counters for
the clock function. The memory addresses 08 to 0F may
be programmed as alarm registers or used as free RAM
locations, when the alarm is disabled.
7.1
When the alarm is disabled (Bit 2 of control/status
register = 0) the alarm registers at addresses 08 to 0F
may be used as free RAM.
7.3
Counter function modes
When the control/status register is programmed, a
32.768 kHz clock mode, a 50 Hz clock mode or an
event-counter mode can be selected.
7.4
Counter registers
In the clock modes 24 h or 12 h format can be selected by
setting the most significant bit of the hours counter
register. The format of the hours counter is shown in Fig.5.
In the clock modes the hundredths of a second, seconds,
minutes, hours, date, month (four year calendar) and
weekday are stored in a BCD format. The timer register
stores up to 99 days. The event counter mode is used to
count pulses applied to the oscillator input (OSCO left
open-circuit). The event counter stores up to 6 digits of
data.
The year and date are packed into memory location 05
(see Fig.6). The weekdays and months are packed into
memory location 06 (see Fig.7). When reading these
memory locations the year and weekdays are masked out
when the mask flag of the control/status register is set.
This allows the user to read the date and month count
directly.
When one of the counters is read (memory locations
01 to 07), the contents of all counters are strobed into
capture latches at the beginning of a read cycle. Therefore,
faulty reading of the count during a carry condition is
prevented.
In the event-counter mode events are stored in BCD
format. D5 is the most significant and D0 the least
significant digit. The divider is by-passed.
When a counter is written, other counters are not affected.
7.2
Control/status register
The control/status register is defined as the memory
location 00 with free access for reading and writing via the
I2C-bus. All functions and options are controlled by the
contents of the control/status register (see Fig.3).
In the different modes the counter registers are
programmed and arranged as shown in Fig.4. Counter
cycles are listed in Table 1.
Alarm function modes
By setting the alarm enable bit of the control/status register
the alarm control register (address 08) is activated.
By setting the alarm control register a dated alarm, a daily
alarm, a weekday alarm or a timer alarm may be
programmed. In the clock modes, the timer register
(address 07) may be programmed to count hundredths of
a second, seconds, minutes, hours or days. Days are
counted when an alarm is not programmed.

Product specification
Remark: In the 12 h mode, bits 6 and 7 of the alarm hours
register must be the same as the hours counter.
An alarm signal is generated when the contents of the
alarm registers matches bit-by-bit the contents of the
involved counter registers. The year and weekday bits are
ignored in a dated alarm. A daily alarm ignores the month
and date bits. When a weekday alarm is selected, the
contents of the alarm weekday/month register will select
the weekdays on which an alarm is activated (see Fig.9).

Event counter mode is selected by bits 4 and 5 which are
logic 1, 0 in the control/status register. The event counter
mode is used to count pulses externally applied to the
oscillator input (OSCO left open-circuit).
Event counter mode
Resolution of the timer is programmed via the 3 LSBs of
the alarm control register (see Fig.11, Alarm and timer
Interrupt logic diagram).
Additionally, a timer alarm can be programmed by setting
the timer alarm enable (bit 6 of the alarm control register).
When the value of the timer equals a pre-programmed
value in the alarm timer register (location 0F), the alarm
flag is set (bit 1 of the control/status register). The inverted
value of the alarm flag can be transferred to the external
interrupt by enabling the alarm interrupt (bit 6 of the alarm
control register).

Interrupt output
The conditions for activating the open-drain n-channel
interrupt output INT (active LOW) are determined by
appropriate programming of the alarm control register.
These conditions are clock alarm, timer alarm, timer
overflow, and event counter alarm. An interrupt occurs
when the alarm flag or the timer flag is set, and the
corresponding interrupt is enabled. In all events, the
interrupt is cleared only by software resetting of the flag
which initiated the interrupt.
7.9
An event counter alarm occurs when the event counter
registers match the value programmed in locations 9, A,
and B, and the event alarm is enabled (bits 4 and 5 which
are logic 0, 1 in the alarm control register). In this event,
the alarm flag (bit 1 of the control/status register) is set.
The inverted value of this flag can be transferred to the
interrupt pin (pin 7) by setting the alarm interrupt enable in
the alarm control register. In this mode, the timer
(location 07) increments once for every one, one-hundred,
ten thousand, or 1 million events, depending on the value
programmed in bits 0, 1 and 2 of the alarm control register.
In all other events, the timer functions are as in the clock
mode.
The event counter stores up to 6 digits of data, which are
stored as 6 hexadecimal values located in locations 1, 2,
and 3. Thus, up to 1 million events may be recorded.

The timer (location 07) is enabled by setting the
control/status register = XX0X X1XX. The timer counts up
from 0 (or a programmed value) to 99. On overflow, the
timer resets to 0. The timer flag (LSB of control/status
register) is set on overflow of the timer. This flag must be
reset by software. The inverted value of this flag can be
transferred to the external interrupt by setting bit 3 of the
alarm control register.

In the 50 Hz clock mode or event-counter mode the
oscillator is disabled and the oscillator input is switched to
a high impedance state.
A 32.768 kHz quartz crystal has to be connected to OSCI
(pin 1) and OSCO (pin 2). A trimmer capacitor between
OSCI and VDD is used for tuning the oscillator (see quartz
frequency adjustment). A 100 Hz clock signal is derived
from the quartz oscillator for the clock counters.

Initialization
It is recommended to set the stop counting flag of the
control/status register before loading the actual time into
the counters. Loading of illegal states may lead to a
temporary clock malfunction.
When power-up occurs the I2C-bus interface, the
control/status register and all clock counters are reset.
The device starts time-keeping in the 32.768 kHz clock
mode with the 24 h format on the first of January at
0.00.00: 00. A 1 Hz square wave with 50% duty cycle
appears at the interrupt output pin (starts HIGH).
7.11
This allows the user to feed the 50 Hz reference frequency
or an external high speed event signal into the input OSCI.

In the clock mode, if the alarm enable is not activated
(alarm enable bit of control/status register is logic 0), the
interrupt output toggles at 1 Hz with a 50% duty cycle (may
be used for calibration). This is the default power-on state
of the device. The OFF voltage of the interrupt output may
exceed the supply voltage, up to a maximum of 6.0 V.
A logic diagram of the interrupt output is shown in Fig.11.
