To connect a PC to the RS-485 terminals or an RS-485 network:
1. Attach the signal converter to the serial or USB port of your PC, using a
25-pin to 9-pin adapter if required.
2. To connect to the RS-485 terminals, open the cover to the wiring
compartment and connect the signal converter leads to the transmitter
terminals labeled
5 and 6, or to the output wires from these terminals. See
Figure 3-2.
3. To connect to an RS-485 network, connect the signal converter leads to any point in the
network. See Figure 3-3.
4. For long-distance communication, or if noise from an external source interferes with the
signal, install 120 Ω, 1/2 watt resistors in parallel with the output at both ends of the
communication segment.
