UNIVERSAL INPUT MODULE — LOGIC I/O
There are two 24-pin logic interface connectors
on the Universal Input module. The left logic con-
nector controls the device attached to the A input;
the right logic connector controls the device attached
to the B input. The logic connectors are hidden by
the meter panel in normal operation. Pages 2-50 to
2-55 show several connection examples.
Note that the Ready and Reset commands are
balanced inputs (they have both a + and - input),
thus for a switch input the + input has to be tied to
Logic 5VDC and the switch tied to Logic
Ground.
Outputs marked with an * are only available when
the module has a Rev. C or later SPROM (21-227-
7). When DS1 (for input A) or DS3 (for input B)
switches 2, 3, or 5 are set to on, then the MIC logic
function is enabled. When switches 2, 3, and 5 are
set to off, then the Line logic function is enabled.
