Connecting the Exciter Communication Line
Two separate RS-485 two-wire interfaces are used to communicate between Readers
and Exciters. For more information, see the 95 Series RFID System Technical Guide.
The RS-485 connectors and jumpers for these lines are located on the Controller
Board CTL95. The CTL95 is the top board of the Reader Module Assembly.
Notes 1. For the RS-485 line, use specially designed cables only
, such as, BELDEN type
9842, or similar. For more information, see the 95 Series RFID System Technical
Guide.
2. To simplify the RS-485 multidrop-type connection, the two RS-485 connectors,
TB4 and TB6, are wired in parallel on the MBD95. Connect the incoming RS-485
cable to one connector and the outcoming RS-485 cable to the other.
To connect the RS-485 communication lines to the Reader, refer to Figure 2-4 below.
