For a detailed description of the settings, refer to the instruction manual for the weighing instrument used.
2-2. Connecting the AD-8920A
(1) Refer to Table 1 shown above to confirm that the communication cable is of the correct type.
(2) Disconnect the AC adapter from both the weighing instrument and the AD-8920A.
Refer to the connection diagram shown above to connect the AD-8920A to the weighing
instrument, using the specified communication cable.
CAUTION
The D-SUB9 cable (standard
or accessory) is for use only
with the AD-8920A.
If used with an older AD-8920,
it could blow the fuse or cause
other damage to the weighing
instrument.
Attach the identification label
on the cable so that it will be
used only with the AD-8920A.
