Connecting the RS-485 Two-Wire Communication Line
The RS-485 is a standard data communication line for an industrial environment. For
detailed information on the two-wire RS-485 interface (half-duplex), see the 95 Series
RFID System Technical Guide. The RS-485 connectors and jumpers are located on the
Motherboard MBD95. The MBD95 is the bottom board of the Reader Module
Assembly.
Notes 1. For the RS-485 line, use specially designed cables only
, such as, BELDEN type
9841, 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 RS-485 communication lines to the Reader, refer to Figure 2-2 below.
