Output A
Two 32-point output-only units (code: C1 and C2) receive
their signals from an input-only unit (code A2). Chs. 1 to 32
of the 64-point input unit are assigned to the signals sent
to the output-only unit of the identical SA, and Chs. 33 to
64 are assigned to those to the unit of this number plus 1.

TRANSMISSION CABLES
• Twisted-Pair Cables
Use wires 0.9 mm dia. or larger.
Connect LINE terminals (+) to (+) and (–) to (–) between
corresponding units.
Transmission will be impossible with as little as one unit's
transmission lines reversed.
In order to prevent noise interference, install transmission
cables in instrumentation cable pits or racks, separate from
power lines.
CORRECT
[Example] Two units
• Fiber Optics
Remove protective covers over the FIBER LINK terminals
and connect FIBER LINK connectors.
Observe appropriate radiuses when bending fiber-optic ca-
bles.
Follow cable manufacturer's installation procedures.
Fiber breakdown can be easily checked: hold a flashlight
toward an end of the cable and see if the light is seen at the
other end.
CORRECT
[Example] Multiple units

EURO TYPE CONNECTOR TERMINALS
Transmission lines (when using twisted-pair cables), power
lines and RUN contact output lines are all connected with
Euro type connector terminals.
The connector can be unplugged from the base. Connect
cables to the screw terminals on the connector.
Use multi-strand cables with pin terminals or solid cables
of ≤ 1.4 mm dia. Do not solder core cable of a multi-strand
cable.
