Terminating resistors

Three DIP switches are provided to enable various terminating resistors to the
RS-485 data bus. The switches are found inside the electronics housing,
located behind an access slot on the upper right side. The switches number
bottom to top 1 through 3 and the upward position is ON.
4.9 Connect to the host system
Procedure
1. Wire the Gateway's Ethernet 1 (Primary) or Serial Output connection
to the Host System Network or Serial I/O (see Figure 1 and Figure 2 for
hardware drawings). This will have to be done for both networks. You
can route the networks to different locations if necessary.
2. For serial connections, make sure all terminations are clean and secure
to avoid wiring connection problems.
