¶ Do not connect the power
supply cord to the AMY
control wire terminal.
Otherwise the P.C.B. in the
AMY adapter will be
damaged.
NOTE In case of emergency, the P.C.B. can be
used by reconnecting CN3 short plug from
A side to B side after correcting wiring.
<Turn off the power supply switch before
reconnecting the short plug>

¶ RS-232C cable
RS-232C cable is used to connect between the
terminals CN4 of the large P.C.B. in S-DDC and Host
Computer. The cable should be fixed to S-DDC with
nylon clamper as shown below.
7 Precautions when wiring AMY control wire
(1) Do not wire the inter-adapter control wiring such as
loop wiring as shown below.
(2) Branch wiring
If branching the inter-adapter control wiring, the
number of branches should be 16 or less.
(Branch length less than 1 m is not included in the
total branch number.)
NOTE
1. Up to 3 wires can be branched off from
the terminal. (Please refer to the following
example of branch wiring.)
2. Branch length less than 1 m is not
included in the total branch number.
3. AMY control wire length between
branches should be 2 meter or more as
shown below.
