The LCD-80FC indicator has resistors built into the circuit board at the In (Terminals 2 & 4) and
the Out (Terminals 1 & 3) for impedance matching. There is no need for the installer to add imped-
ance matching resistors.
Refer to the following illustrations for EIA-485 connections from the LCD-80FC to the MS-
