17
(1,200 m) total per port. Use twisted pair (minimum 24 AWG) with shield for
communication. The default speed of this port is 38.4Kbps but it can be downgraded
to 19.2Kbps or 9.6Kbps if the line conditions or receiving equipment require it (see
Table 1 on page 3 for jumper settings and Table 2 on page 4 for DIP switch settings).
For wiring to an RS-485 port:
1. TR+ is the plus side of the transmit and receive differential signal.
2. TR- is the negative side of the transmit and receive differential signal.
3. GND is the signal ground.The wiring for this signal is required and NOT optional.
This signal must NOT be connected to chassis GND.
4. Use 24 AWG low capacitance, twisted-pair, shielded cable (Honeywell 3328 or
equivalent).
