software may require the use of an RS-485 to RS-232 converter, as most PCs cannot be
wired directly to RS-485.
To wire the RS-485 cable to the Base Radio we recommend using a 22AWG twisted pair
shielded wire. Place one of the twisted pair wires in the “A” (Tx+/Rx+) slot of the same
terminal block as the power supply wires, and the other wire in the “B” (Tx-/RX-) slot of
the terminal block as shown below in Figure 3-5.
Figure 3-5 Wiring RS-485 to the Base Radio
RS-485 may be wired in-line (in series) to multiple Base Radios. This is called “daisy-
chaining”. Only Base Radios using Modbus RS-485 output can be daisy-chained. See
Section 3.2.6. Note that Base Radios daisy-chained must be set to different RF Channels
to communicate properly on the same wire.
3.2.4 Wiring the RS-485/232 Converter to the Base Radio
Honeywell offers an optically isolated, surge protected, DIN Rail mountable RS-485/232
converter, AIC #. Because there are many RS-485/232 Converters available, please see
your converter’s instruction manual for details as this section will only discuss the wiring
of the B&B 485LDRC9 converter.
The Base Radio communicates via a RS-485 half-duplex differential signal with A being
Tx+/Rx+ and B being Tx-/Rx-. To properly wire the Base Radio to the 485LDRC9, you
should follow Figure 3-6.
