Brief Description
This board is designed for use with the CML EV6020 and EV6040 Evaluation Kits, which are in turn
used for evaluation of the FX602, FX604 and FX614 products. The EV6000 Evaluation Kit comprises
one board containing a socket for a UV-erasable PIC µC which the user may program and control via
the RS232 serial interface. With the aid of suitable applications software, the user can demonstrate the
use of the FX602, FX604 or FX614 in telecommunications applications. The EV6000 board may be
powered from a single 8 - 35V dc power supply; an on-board regulator sets 3.3V or 5.0V operation.
The PIC µC may be driven from an external clock, or from its own crystal oscillator. Test point hooks
provide access to programming voltages. Space has been left for the user to ZIF-socket the PIC µC, if
required. Interconnecting cables are provided for an RS232 link to a PC and for 20-way flat cable
connections to other CML evaluation kits or other parts of a user's system.
This EV6000 Evaluation Kit is designed to be a general purpose product which may be used to support
other CML evaluation kits in the future. Applications software is being regularly updated and users
should contact CML for further details.

Quick Start
This section provides instructions for users who wish to experiment immediately with the evaluation kit.
A fuller description of the kit and its use appears later in this document.
1.3.1
Setting-Up
This evaluation kit comprises a single board containing a socket for a 40-pin DIL PIC (or compatible)
general-purpose µC, which the user may re-program with his applications software.
THE EV6000 COMES WITH A PRE-CONFIGURED PIC 16C74AJW OR EQUIVALENT,
CONTAINING DIAGNOSTIC FIRMWARE AND APPLICATION SPECIFIC DEMONSTRATION
FIRMWARE FOR THE EV6020 AND EV6040 EVALUATION KITS. THE EV6000 IS SET FOR
OPERATION AT 5.0V.
The kit also contains two 20-way flat cables (one of which is needed for connection to an EV6020 or
EV6040 CML Evaluation Kit) and a 9-way D-type RS232 cable (for connection to a PC), as shown in
the Block Diagram of Figure 1. No board adjustments are required by the user.
BEFORE APPLYING POWER, PLEASE CHECK THE FOLLOWING:
ENSURE THE PIC µC IS PLUGGED INTO SOCKET U2 ON THE EV6000 BOARD.
CONNECT THE 9-WAY RS232 CABLE BETWEEN SOCKET J3 AND THE SERIAL PORT OF A PC.
FOR USE WITH EV6020 OR EV6040 EVALUATION KITS, CONNECT A 20-WAY FLAT CABLE
BETWEEN SOCKETS J1 ON THE EV6000 AND EV6020 OR EV6040 BOARDS.
The EV6000 board has connections for a single 8 - 35V dc power supply. Only one board (as shown in
Figure 1) needs to be connected as power is supplied to the other board over the flat cable. Each
board has its own power supply regulator chip, with a jumper to select 3.3V or 5.0V (default) operation.
MAKE SURE BOTH BOARDS HAVE THIS JUMPER SET TO THE SAME VOLTAGE. DAMAGE
MAY RESULT IF THIS STEP IS NOT OBSERVED. DO NOT OPERATE EITHER BOARD WITH ITS
VOLTAGE SELECTION JUMPER REMOVED.
Ensure that the component value jumpers on the EV6020 or EV6040 evaluation board are correctly set
for 3.3V or 5.0V operation. Please refer to Section 1.6.1.1 for further details.
Connect any other equipment as shown in Figure 1.
Ensure the PC terminal emulator program is set up as detailed in section 1.2.1.2.
1.3.2
Operation
The EV6000 kit is designed to control the operation of an EV6020 or EV6040 Evaluation Kit. The
firmware which is pre-configured into the PIC µC has both diagnostic and application specific
commands. Refer to section 1.6.2.2 for the diagnostics and section 1.6.2.3 for the applications.
The PICPROGA.EXE program can be used to re-program the PIC µC firmware, if required.

Detailed Description
1.6.1
Hardware Description
EV6000
1.6.1.1 Operating Voltage
The selection of operating voltage (VDD = 3.3V or 5.0V) by jumper JP1 affects the choice of
component values around the evaluation device on the EV6020 or EV6040 Evaluation Kit. Care should
be taken to ensure that JP1 is set the same way as jumpers JP1, JP3, JP4, JP5, JP6 and JP7 on the
EV6020 or EV6040 Evaluation Kit.
1.6.1.2 Clock/Oscillator
A 4MHz xtal is the highest frequency xtal that may be used with a PIC16LC74(A)JW at
VDD = 3.3V. The PIC 16C74(A)JW has a similar limitation and is fitted for availability reasons.
Although rated at 5.0V, it has been found to work successfully at 3.3V. Two jumpers JP2, which are
normally fitted, select an on-board 4MHz xtal. An external 3.58MHz clock, for example, may be
supplied to JP2_1 (1) once the jumpers have been removed, taking care to adjust any firmware timing
routines accordingly.
1.6.1.3 RS232 Interface
The RS232 interface (connector J3) has its communications protocol determined by the µC firmware.
A suggested configuration is 8 data bits, no parity, 1 stop bit and 19,200 baud with hardware
handshake but without CR -> CR/LF conversion. Linefeeds are provided by the EV6000 firmware.
The firmware supplied in the PIC µC assumes this configuration.

EV6000
Software Description
1.6.2.1 PIC µC Programming Software
This is supplied on disk as a self-documented executable file PICPROGA.EXE for a PC running DOS
(either directly or as a DOS window in Windows 3.11 or '95). It is not recommended for use on
Windows NT systems. Please note that this programming software does not meet the Arizona
Microchip Technology verification requirements for a "production quality" programmer. Also, it does not
support the programming of ID locations and there is no checksum facility.
The user interface consists of two windows. The top window contains the operating instructions and the
bottom window shows the command line and data communications with the PIC µC. When the top
window first appears the user will be prompted to enter the number of the serial communications port to
which the EV6000 board is connected. Once the user has entered this number, the following
commands are displayed:
press F
to load file.
press C
to enter Configuration Word.
press B
to check target device is blank.
press P
to program target device.
press V
to verify target device.
press R
to read target device.
press A
to view contents of program data array.
Currently - xxxx
press Esc to return to DOS.
A new function from the above table can be selected whenever the >ok prompt appears in the bottom
window.
Notes:
a) Assembler output files must be in the Intel hex format (.HEX) in order to be usable by this
programming software.
b) The PIC µC supplied has a Configuration Word which is preset to 3FB9H if it is a PIC 16C74JW or
16LC74JW, or to 3FB1H if it is a PIC 16C74AJW or 16LC74AJW. In each case, this selects the
crystal oscillator, disables the watch dog timer, enables the power up timer and disables code
protection. The programming software currently defaults to 3FB1H. Consult Arizona Microchip
Technology for more information on the Configuration Word.
c) The "blank check" command (B) only looks at the first location. A programmed device will always
have data in this location as it is the program start address.
d) For each of the commands B,P,R and V the user will be prompted to manually reset the target µ
C, by pressing the RESET switch (SW1) on the EV6000 Evaluation Board. This is because PIC
programming always starts from location 0000 and the program counter can only be incremented.
e) Pressing A will display the program data in the bottom window, formatted in pages of 48
consecutive locations. Use the <PageUp> and <PageDown> keys to scroll through the data.
Pressing <Esc> will return the user to the >ok prompt.

1.6.2.2 EV6020/EV6040 Diagnostic Firmware
This is supplied both as a collection of assembler source routines on disk and pre-programmed into the
PIC µC, where it is identified as EF6000. The diagnostic and applications firmware supplied may be
replaced or supplemented by the user's own applications firmware. The PIC µC firmware is controlled
by a terminal emulator program, from a PC with Windows 3.11, '95 or NT.
Text commands are entered by the user into the terminal emulator. Characters are not case sensitive.
There is a global limit of 6 characters on any user input string. Whenever the >ok prompt is
displayed a new command may be entered and should be terminated by pressing the <Return> key.
Whenever a command has been entered, the > prompt is returned if data entry is required. To use a
function, the appropriate set-up commands must be entered before-hand. For example, to use the
EV6040 to transmit external data to the line, the following should be entered:
>ok
6040<Return>
>ok
tx<Return>
>ok
txext<Return>
>
; sets EV6000 for use with the EV6040
; sets the FX604 into Tx mode

output. The FX602/FX604 is operated with data retiming selected.
txtxt Enter a mode where text entered by the user or downloaded as a text transfer is
transmitted by the FX604. The FX604 is operated with data retiming selected.
txext Enter a mode where raw data can be applied by the user to connector J2 pin 2 on the
EV6000 board for transmission at 1200 baud by an FX604 on the attached
EV6020/EV6040 board. A clock output is provided on J2 pin 1 of the EV6000 board,
the positive-going edge of which may be used to latch data on to J2 pin 2.
rxext Enter a mode where raw data which has been received by an FX602 or FX604 at 1200
baud on the attached EV6020/EV6040 board can be read by the user on connector J2
pin 2 of the EV6000 board. A clock output is provided on J2 pin 1 of the EV6000
board, the positive-going edge of which may be used to latch data from J2 pin 2.
Notes:
Some terminal emulators have been found not to support full hardware flow control when transferring
text files. This could result in data loss when using the txtxt command. If this problem is
experienced, users should try using a lower data rate or a different terminal emulator.
The PIC I/O line (J2 pin 1) which is used for the rxext and txext commands is an open-collector
output with only a weak, 1MΩ, pull-up resistor fitted to the EV6000 board.

1.6.2.3 Applications Software
(a)
Application/Demonstration Commands
cas
(Press <Esc> to exit these functions)
Follows the CAS detection part of the CIDCW algorithm detailed in the FX602 data
sheet. Near end speech is input between TP18 and VSS (TP1 or TP2 ). If the detect
output is set for a time longer than T1, the near end speech path (TP18 to the line) is
muted. If the detect output then remains set (making a total detect time longer than T3
but less than 65ms) then, after a quiet period of 50ms, the DTMF digit "D"
acknowledgement tone is transmitted down the line.
Once this sequence has been completed, or aborted for not meeting a timing
requirement, the near end speech path is un-muted and the FX602 returned to tone
alert mode.
On the EV6020 board, the line termination resistor R20 (≈ 600Ω) should be fitted.
Note that this software does not present an off hook dc load to the line.
casd
Operates as above, but two decimal counters are run. The first counts the number of
times the near end speech is muted and the second counts the number of times the
DTMF acknowledgement is sent. The results are displayed and updated in the form:
M=00000000,A=00000000.>
where M represents mutes of the near end speech path and A represents
acknowledgement tones sent.
On the EV6020 board, the line termination resistor R20 (≈ 600Ω) should be fitted.
Note that this software does not present an off hook dc load to the line.
cast
This enables the user to adjust the CAS detection algorithm timings T1 and T3. The
user is prompted as follows:
T1=3A98>
Type <Return> for no change, or enter the new setting (in µs) in hex.
e.g.
For T1 = 10ms = 10,000µs = 2710hex, type 2710<Return>
The user is then prompted to alter T3 in the same way. The default settings are T1 =

cidcw This demonstration covers both the BT and Bellcore off-hook caller ID services. The
CAS detection algorithm runs as detailed for cas but once the DTMF
acknowledgement is sent the FX602 is set to receive mode and the FSK data is
displayed in the form of these examples:

On the EV6020 board, the line termination resistor R20 (≈ 600Ω) should be fitted.
Note that this software does not present an off hook dc load to the line.

This demonstration covers the BT on-hook service initiated by a line reversal. On the
EV6020 board, JP1 should be in position 2-3 for detection of a line reversal. The idle
condition is with the FX602 in zero power mode and with IRQN enabled. When a line
reversal is detected the FX602 is set to tone alert mode. Once the alert tone is
detected the FX602 is set to receive FSK data, which is displayed in the same way as
for cidcw.
On the EV6020 board, relay 2 is energised for 15ms during the silent period between
the alert tone and the FSK data. A resistor can be fitted in the R26 position to provide
a current wetting pulse. Relay 3 is energised during the FSK receive period.
Components can be fitted in positions R30, R36 and C10 to provide an ac termination
to the line.
cid
This demonstration covers the Bellcore on-hook service associated with ringing. On
the EV6020 board, JP1 should be in position 1-2 for detection of ringing. The idle
condition is with the FX602 in zero power mode and with IRQN enabled. A detect
pulse of duration < 500ms is assumed to be a line reversal and is ignored. When a
burst of ringing current is detected the FX602 is set to receive FSK data, which is
displayed in the same way as for cidcw.
On the EV6020 board, relay 3 is energised during the FSK receive period.
Components can be fitted in positions R30, R36 and C10 to provide an ac termination
to the line.

This demonstration covers the NTT on-hook service associated with ringing. On the
EV6020 board, JP1 should be in position 1-2 for detection of ringing. The idle
condition is with the FX602 in zero power mode and with IRQN enabled. A detect
pulse of duration < 500ms is assumed to be a line reversal and is ignored. When a
burst of ringing current is detected the FX602 is set to receive FSK data, which is
displayed in the form of the following example:
