IMPORTANT!
Plugs may be interchanged for testing or other operations without
damage, but the mapping of ICS Tie signals
will be affected
at
connector
J1008
as these cables are moved to other stations.
Likewise, radio plugs may be changed for trouble-shooting
purposes, but the mapping to specific switches on a control
station
will then be changed
.
NEVER exchange transceiver and receiver connectors
, as
they have different signals on their pins, and loss of functionality
will result.
Tape player connector J1012 is KEYED with a
blocking pin
to
prevent mis-mating, as this line can be
damaged by incorrect
installation
at the A740.
For best results, the
cables should be dressed at the A740 so
that the correct A740 location is
clear by cable length and
location
, as well as a connector label tag on each plug.
