1.2 Product Description
1.3 Associated RFMs
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 thecommands from the host to send signals and to receive data from a transponder. It decodes the receivedRF signals into the transponder’s identification number, checks the validity, and handles the protocolconversion 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 anRS-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 andTBP 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 applicablespecific requirements.
The Control Module has eight configurable digital input/outputs that can be defined by the user and twoopen collector outputs. It also includes a wireless synchronization feature and a port to allow wiredsynchronization to avoid interference between readers located close to each other.
Four indication LEDs show the status of the module.
The S2000 Control Module works together with the Radio Frequency Modules listed in Table 1-1 .

2.4 Software Configuration
Software Configuration
The Texas Instruments utility "S2_Util.exe", which is available at www.ti-rfid.com , can be used to configurethe Series 2000 Control Module according to the customers application specific requirements concerning:
Communication protocol
Communication parameters
Default read mode
RF Module parameters
Synchronization type
Default I/O settings
Dip-switch S1 (S1.1) determines the mode of operation of the Control Module. If Dip-switch S1.1 is in theOFF 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 theControl Module. These application specific parameters are stored in serial EEPROM on the ControlModule.
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 eithervia a communications port or via the USB service port. Connect one of these ports to the Host and getconnection using the standard reader settings by switching S1.1 to the OFF position. Change the defaultparameters to customer parameters and save them. Then after moving Dip-switch S1.1 to the ONposition, 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 orTIRIS Bus Protocol Reference Guides which are available at Texas Instruments’ RFID internet site:www.ti-rfid.com .

2.5 Power Supplies
2.5.1 Common DC Power Supply for Both Control and RF Modules
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 (seeSection 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 Section2.5.2).
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 Section2.5.3).
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 OperatingConditions. Electrical Characteristics for minimum,nominal and maximum inputsupply levels. For RFM power supply requirements please refer to the relevantRFM Reference Guide.
CAUTION
Please be very careful to ensure that you use the correct polarity in all of thesemethods of Power Supply as there is no reverse polarity protection built into theControl Module.
Figure 2-4 shows how to connect a regulated power supply for both the Control Module and the RFM.Jumper JP6 must be closed.

2.5.4 Battery Backup for Memory
Power Supplies
If a non-regulated DC Power Supply is used to supply the Control Module logic circuits, it should beconnected to the reader as shown in Figure 2-5 . Jumper JP6 must be closed.
Figure 2-5. Non-Regulated Power Supply
If you use a regulated (5 V) Power Supply for VCC2, it should be connected to the reader as shown inFigure 2-6 . Jumper JP6 must be removed.
Figure 2-6. 5V Regulated Control-Logic Power Supply
Even though the Series 2000 Control Module remains powered, it is possible the memory contents maybe erased when the Control Module is reset. This occurs when power is temporarily removed from theRAM 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 followingprecautions 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 recommendthat you take the following precautions:
Connect a battery (with VCC3 nominally 3.0 V) between pins 6 (+) and 7 (–) of ST22 as shown inFigure 2-7 , instead of a bridge between VCC2 and VCC3. Tolerances for the battery are given inSection 3.2.1.1.

Figure 2-7. Battery Backup for Memory
The Service/Configuration Interface allows both RI-CTL-MB2B and RI-CTL-MB6B to be configured via aUSB 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
A host (usually a PC) is needed to control the Series 2000 Control module. The computer can either besituated 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 ControlModule (RI-CTL-MB2B) can be used; if it is further away the RS-422 or RS-485 version (RI-CTL-MB6B)should be used.

The Data Rate, Parity, Data bits and Handshake can be configured using the S2_Util as described inSection 2.4.
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
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 remotecontrolled 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 isactivated.
Figure 2-10 shows the circuitry of the RS-422/485 Interface. Jumper 2 (JP2) must be closed to provideline-to-line termination. If the PC is at one end of the line, it must be terminated at its RX+/RX- Inputs. Thereader at the end of the line must be terminated. If the PC is connected somewhere in the middle of theline, 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 isexplained in detail in sections 2.7.3.1 and 2.7.3.2.

2.8.2 Wired and Combined Wireless/Wired Synchronization
2.8.3 Master/ Slave Synchronization without Acknowledgement; Triggered
Synchronization Interface
To allow the synchronization of up to 32 readers, the Series 2000 firmware provides six types ofsynchronization (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, combinedwireless/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 youhave installed, and then set the dipswitch S1.1 to the ON position.
Figure 2-15 shows the way in which the Control Module must be connected for a wired and combinedwireless and wired synchronization. The Control Module also has to be software configured to the chosensynchronization method. Table 2-13 explains the setting of jumpers 12, 13 and 14 (JP12, JP13 and JP14).

Figure 2-16 shows the way that the Series 2000 readers have to be connected for Master/ Slavesynchronization or Triggered synchronization, both without acknowledgement. The individual SWconfiguration (Master or Slave) is shown in Table 2-14 and Table 2-15 . The tables also explain the settingof jumpers 12, 13 and 14 (JP12, JP13 and JP14).
