Inc. Part No. 800-0070-00). 1.2 DESCRIPTION The Interface Model 2022 is termed Multiplex because it can manage up to 16 addressable Readers and Antennas using time division multiplexing. The Interface Model 2002 provides a full-duplex, asynchronous bit serial data stream which will interface to various equipment compatible with RS-232-C,RS-422-A, or RS-423-A specifications. -

The power is provided through the Eurocard connector 64 pin DIN and signal connections are made via a terminal strip on the printed circuit board. If the RFID, Inc. enclosure assembly is not provided for the Eurocard, you must provide a Eurocard DIN connection with +5v on pins a1,c1, and ground on pins a32, c32. -

19200 2.10.4 SERIAL CABLING The Model 2022 Interface connects to the host via 25-pin, female "D" connector - P2. Therefore, a cable with a 25-pin, male "D" connector on one end and the appropriate connector required for the host on the other end must be built or purchased. - Page 14 thing is to connect the Interface's Transmit Data (TD) signal (pin 2) to the host's Receive data (RD) signal, the Interface's Receive Data (RD) signal (pin 3) to the host's Transmit Data (TD) signal, and the Interface's Ground (pin 7) to the host's Ground. The table below lists the signals present on the Interface's DB-25 connector P2 and their usage for each of the possible RS interface standards.

The power up message is preceded by a Line Feed (<LF>) and followed by a Carriage Return (<CR>) like all messages out of the Interface. For the Model 2022, the power up message consists of an 18 character string:... -
Page 16: Section 3 - Operation
SECTION 3 OPERATION 3.1 INTRODUCTION This section explains operating information for the Interface. It describes its theory of operation, timing, commands, operating modes, and responses. 3.2 THEORY OF OPERATION The Interface has 3 main functions: 1) monitor the SIGNAL inputs from the Readers for the presence of Electronic Tag data, 2) generate pulses on the ENABLE lines to control the Readers so that only one is enabled at any time, and 3) communicate over the serial interface to meet the specific needs of the user. -
Page 17: Timing
To increase physical Tag speeds to an even greater level, there exists a Model 2022/8, the slash 8 standing for 8 character Tags instead of the normal 16. While not heavily marketed, since it reads Tags programmed with shorter data strings, the Model 2022/8 can detect, process, and transmit the messages faster. - Page 18 The equation can be used to prove the results of the worse case delays calculated earlier. A Model 2022 with 16 Readers and 10,000 Tags has #P of 16 since only 16 can be read at once, if the Model...

Page 19: Timing Summary
These Tags could travel at: Rate = 0.7 ft / .545 sec, or 1.28 feet per second. If eight Readers were eliminated from the Model 2022's polling loop via the Assign Command #S becomes 8 and the equation works out: Td = 2 * (.050 + .0125) + (8 - 2) * .030... -
Page 20: Data Protocol
Td = time to detect and report all reportable Tags = #P * (Tr + Tt) + (#S - #P) * Tn 3.4 DATA PROTOCOL The data protocol utilizes ASCII characters for all data from the Interface and all control functions from the host computer. - Page 21 The results of each test are transmitted as they are completed with a "1" indicating the successful completion of a test and a "0" indicating failure. If any of these tests fail, contact RFID for corrective action. Successful self test will read as follows: "111111111(Vn.nn)"...
- Page 22 Reader is to be skipped. The first digit following the command "A" corresponds to the highest addressed Readers F thru C and the last digit corresponds to the lowest addressed Readers 3 thru 0. The most significant bit of each digit corresponds to the highest addressed Reader of that group.
- Page 23 information immediately to the host system, once. Mode #2 - [M2] Polled Operation This mode also continually scans the Reader for Tag reads, but stores the data for subsequent retrieval when requested by the host computer. Due to limited processor memory, only two Tags can be buffered by the Interface, therefore, care must be taken to ensure that the Interface is polled frequently enough that no Tags are missed because of full buffers.
- Page 24 4-digit access key, and this can only be done transparently using an RFID, Inc. Programmer. The access key is an integral part of the Interface's user-transparent, error detection field so that a Tag programmed with anything other than the set access key will not be recognized at all.

Page 25: Interface Responses
A Tag will report as <LF># xxxxxxxxxxxxxxxx<CR> where the # symbol represents the Reader address where the Tag was detected, followed by an ASCII space. In the case of an 8 character Interface Model 2022/8, Tags may only be programmed with the ASCII representations of 0-9 A-D. -
