Series 2000 Control Module 10 Introduction SCBU044 (11-09-21-077) – January 2008 Submit Documentation Feedback www.ti.com Product Description 1.2 Product Description The Series 2000 Control is the interface between a Texas Instruments’ Radio Frequency Module (RFM) and a controlling host. It controls the transmit and receive functions of the RFM according to the commands from the host to send signals and to receive data from a transponder. It decodes the received RF signals into the transponder’s identification number, checks the validity, and handles the protocol conversion to a standard serial interface. The Control Module is offered with two different interfaces: • RI-CTL-MB2B for point-to-point communication via an RS-232 interface • RI-CTL-MB6B for point-to-point via an RS-422 interface or point-to-multipoint communications via an RS-422/485 interface. There are two communications protocols available: • TIRIS Bus Protocol (TBP) that can be used with point-to-point or point-to-multipoint systems • ASCII Protocol for use with point-to-point systems. For details regarding the communications protocol (ASCII or TBP) please refer to the ASCII Protocol and TBP Reference Guides which are available at Texas Instruments’ RFID internet site: www.ti-rfid.com. The Control Module can be configured via the USB or standard serial interface according to applicable specific requirements. The Control Module has eight configurable digital input/outputs that can be defined by the user and two open collector outputs. It also includes a wireless synchronization feature and a port to allow wired synchronization to avoid interference between readers located close to each other. Four indication LEDs show the status of the module. 1.3 Associated RFMs The S2000 Control Module works together with the Radio Frequency Modules listed in Table 1-1. Table 1-1.

If Dip-switch S1.1 is in the OFF position, standard default parameters are used. These are: • RI-CTL-MB2B – ASCII protocol – 9600 baud, eight databits, no parity, one stop bit, Xon/Xoff enabled – Normal mode – RF module power RFM-007 (also valid for RFM-008) – Wireless synchronization – I/O 0 to 3 defined as input – I/O 4 to 7 defined as output and logic high – Hardware interface RS-232 • RI-CTL-MB6B – ASCII protocol – 9600 baud, eight databits, no parity, one stop bit, Xon/Xoff enabled – Normal mode – RF module power RFM-007 (also valid for RFM-008) – Wireles synchronization – I/O 0 to 3 defined as input – I/O 4 to 7 defined as output and logic high – Hardware interface RS-422 If Dip-switch S1.1 is in the ON position, customer specific default parameters are used to operate the Control Module. These application specific parameters are stored in serial EEPROM on the Control Module. Note: Dip-Switch S1.1 is checked at power-up, after a software RESET and during operation. Configuration changes will become active as soon as the switch is moved. To enable the customer specific parameters to be changed the Control Module can be configured either via a communications port or via the USB service port. Connect one of these ports to the Host and get connection using the standard reader settings by switching S1.1 to the OFF position. Change the default parameters to customer parameters and save them. Then after moving Dip-switch S1.1 to the ON position, the Control Module will work with the customer specific parameters. For details regarding the communication protocol (ASCII or TBP), please refer to the ASCII Protocol or TIRIS Bus Protocol Reference Guides which are available at Texas Instruments’ RFID internet site: www.ti-rfid.com. 18 Installation SCBU044 (11-09-21-077) – January 2008 Submit Documentation Feedback www.ti.com Power Supplies 2.5 Power Supplies In this section we describe the various Power Supply possibilities for the Series 2000 Control Module. These are: • The Series 2000 Control Module and RF Module are both powered by a regulated Power Supply (see Section 2.5.1). • The Control Module and the RF Module logic circuitry are powered by a non-regulated Power Supply, and the RF module power circuits are separately supplied by a regulated Power Supply (see Section 2.5.2). • The Control Module and the RF Module logic circuitry are powered by a regulated (5 V) Power Supply, and the RF Module power circuits are separately supplied by a regulated Power Supply (see Section 2.5.3). When the Series 2000 Control Module control logic circuitry is powered by an external regulated (5 V) Power Supply, Jumper JP6 must be left out. CAUTION The supply voltage range that can be used depends on the RFM used, therefore in all cases, refer to section 3.2.1 Recommended Operating Conditions. Electrical Characteristics for minimum,nominal and maximum input supply levels. For RFM power supply requirements please refer to the relevant RFM Reference Guide. CAUTION Please be very careful to ensure that you use the correct polarity in all of these methods of Power Supply as there is no reverse polarity protection built into the Control Module. 2.5.1 Common DC Power Supply for Both Control and RF Modules Figure 2-4 shows how to connect a regulated power supply for both the Control Module and the RFM. Jumper JP6 must be closed. Figure 2-4. Single Power Supply for Both Control and RF Modules SCBU044 (11-09-21-077) – January 2008 Submit Documentation Feedback Installation 19 www.ti.com Power Supplies 2.5.2 Non-Regulated DC Power Supply (Without Memory Backup) If a non-regulated DC Power Supply is used to supply the Control Module logic circuits, it should be connected to the reader as shown in Figure 2-5. Jumper JP6 must be closed. Figure 2-5. Non-Regulated Power Supply 2.5.3 Regulated DC Power Supply (Without Memory Battery Backup) If you use a regulated (5 V) Power Supply for VCC2, it should be connected to the reader as shown in Figure 2-6. Jumper JP6 must be removed. Figure 2-6. 5V Regulated Control-Logic Power Supply 2.5.4 Battery Backup for Memory Even though the Series 2000 Control Module remains powered, it is possible the memory contents may be erased when the Control Module is reset. This occurs when power is temporarily removed from the RAM during reset. A reset can be initiated in one of three ways: • Internally by the reset/watchdog circuit • Externally by using the reset input (pin 3 of ST33) • Externally by the RS-232 DTR signal (RI-CTL-MB2B version only) In order to prevent memory contents being lost during a reset, we recommend that the following precautions are taken: • Connect VCC2 (pin 5 of ST22) and VCC3 (pin 6 of ST22) to each other. In order to prevent memory contents being lost during a power-down, or during a reset, we recommend that you take the following precautions: • Connect a battery (with VCC3 nominally 3.0 V) between pins 6 (+) and 7 (–) of ST22 as shown in Figure 2-7, instead of a bridge between VCC2 and VCC3. Tolerances for the battery are given in Section 3.2.1.1. 20 Installation SCBU044 (11-09-21-077) – January 2008 Submit Documentation Feedback www.ti.com Service/Configuration Interface Figure 2-7. Battery Backup for Memory 2.6 Service/Configuration Interface The Service/Configuration Interface allows both RI-CTL-MB2B and RI-CTL-MB6B to be configured via a USB serial port. A mini-USB B to USB A cable will be required for most connections. For USB operation jumper, JP11 must be in place. Figure 2-8. USB Interface 2.7 Serial Communication Interface A host (usually a PC) is needed to control the Series 2000 Control module. The computer can either be situated at the reader site, or it can be at a remote location. If the distance between the reader and the computer is less than 20 m, the RS-232 version of the Control Module (RI-CTL-MB2B) can be used; if it is further away the RS-422 or RS-485 version (RI-CTL-MB6B) should be used. SCBU044 (11-09-21-077) – January 2008 Submit Documentation Feedback Installation 21 www.ti.com Serial Communication Interface 2.7.1 Interface Configuration The Control Module firmware uses the following configuration: Start/Stop bit XON /XOFF XON = 17OEC, XOFF = 19DEC The Data Rate, Parity, Data bits and Handshake can be configured using the S2_Util as described in Section 2.4. 2.7.2 RS-232-C Interface The recommendation for connection to a 9-pin sub-D interface connector is given in Figure 2-9. Figure 2-9. RS-232 9-Pin Interface Connection 2.7.2.1 Activation (RI-CTL-MB2B) The Data Terminal Ready (DTR) signal is connected to the reset/watchdog circuit of the Control Module. This ensures a PC controlled microcomputer initialization before the default Read Mode is started. If you want to run the Control module in a 3-wire connection (RXD, TXD, and GND), without remote controlled activation, Jumper 5 (JP5) must be closed. This connects DSR and DTR together. When power is applied to the Control Module the Data Set Ready (DSR) of the RS-232, interface is activated. 2.7.3 RS-422/485 Interface Figure 2-10 shows the circuitry of the RS-422/485 Interface. Jumper 2 (JP2) must be closed to provide line-to-line termination. If the PC is at one end of the line, it must be terminated at its RX+/RX- Inputs. The reader at the end of the line must be terminated. If the PC is connected somewhere in the middle of the line, then the readers at either end must be terminated. Jumper JP4 and JP5 determine which of the two interface types is selected (RS-422 or RS-485). This is explained in detail in sections 2.7.3.1 and 2.7.3.2. 22 Installation SCBU044 (11-09-21-077) – January 2008 Submit Documentation Feedback www.ti.com Serial Communication Interface Figure 2-10.

Synchronization Interface Connector SCBU044 (11-09-21-077) – January 2008 Submit Documentation Feedback Installation 25 www.ti.com Synchronization Interface To allow the synchronization of up to 32 readers, the Series 2000 firmware provides six types of synchronization (or No Sync if you are not going to use synchronization) • Wireless synchronization • Wireless • Wired • Combined wireless/wired • Master/slave (with or without acknowledgement) • Triggered This specification covers the way the readers have to be connected for the wired, combined wireless/wired, Master/Slave and triggered synchronization. When you have completed the hardware synchronization, you must run the configuration utility (S2_Util.exe) as described in Section 2.4, in order to tell the system which synchronization method you have installed, and then set the dipswitch S1.1 to the ON position. 2.8.2 Wired and Combined Wireless/Wired Synchronization Figure 2-15 shows the way in which the Control Module must be connected for a wired and combined wireless and wired synchronization. The Control Module also has to be software configured to the chosen synchronization method. Table 2-13 explains the setting of jumpers 12, 13 and 14 (JP12, JP13 and JP14). Figure 2-15.
