Figure D-6 Twenty-Six Pin Connector Showing Terminal Designators (RF
Module)
The cabling, should be Belden 9732 or equivalent, nine-pair, twisted-shielded pair,
maximum length 152 m (500 ft).
Power Connector
This connector is a 3-pin circular plug.
Reader-to-RF Module Communications
The communication channel provides bi-directional communication between the
reader logic card and the RF module. This channel is a differential I/O that provides
two-way communication via half-duplex channels. Differential transmission provides
signal integrity over long cable distances and in electrically noisy environments. This
channel supports communication rates up to 19.2 Kbaud, with cable lengths up to 152
m (500 ft).
The command/response communication channel is implemented in a microchip
PIC16-series microcontroller, with the protocol executed in software that provides
flexibility for future applications. Frequency and power attenuation settings are stored
by the microcontroller in nonvolatile memory. A programming interface is provided
so that the new software can be downloaded into the PIC16 device.
The reader-to-RF module interface performs the following functions:
•
Receives two discrete, differential input signals from the reader logic card for RF
power on/off control.
