The termination cable plugs into the DB-9 connector located
at the upper right corner of the termination panel.
Thermocouple inputs are terminated at the screw terminals
located along the bottom of the termination panel. These
terminals are arranged in three groups of eight inputs. Two
screw terminals are provided for each thermocouple input.
Two additional ground terminals within each group are
provided to connect thermocouple cable shield wires if desired.
Termination Panel Indicators
The termination panel has status indicators for power supply
voltages, and transmit data. When positive and negative
supply voltages are present at the termination panel, the
POWER + and POWER - indicators are on. The TX DATA
indicator is on when the Mux is transmitting data to the input
module. Normally, all these green indicators should be on.
