Terminating resistances
For best performance, the terminating resistances should be
matched across the 1410D, 781, and the signal barrier. The 1410D
has an integral 250 Ω terminating resistor. Short the 781 terminator
terminals to engage a 250 Ω resistor (see
The recommended barriers can also be switched to 250 Ω .

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 input/output
(I/O) (see
2. For serial connections, make sure all terminations are clean
and secure to avoid wiring connection problems.
