It is possible to connect the balance to peripheral devices, PCs, PLCs, etc. by using the RS-232C
connector and the USB miniB connector which are provided as standard with the balance.
To print the weighing result measured with the balance on paper, connect a specialized balance
printer (e.g. AD-8127 Compact Printer) to the device.
□ Connect the balance with the printer using the RS-232C cable.
For settings when connecting the balance to the printer, refer to section 4, “Connecting to the
printer”.
When confirming the weighing values or operating the balance with keys remotely, connect the
specialized external display unit to the balance. The specialized external display unit consists of the
external display unit AD-8920A (display only) and the external controller AD-8922A.
□ Connect the balance to the external display unit using the RS - 232C cable.
For settings when connecting the balance and the external display unit, refer to section
5, ”Connecting to the external display unit".

□ When connecting the balance to an external display unit and a printer, connect the balance
with the external display unit (external controller AD-8922A only) with a RS-232C cable and
connect the external display unit and the printer with a RS-232C cable.
When converting the weighing values of the balance into electronic data or when remotely
controlling the balance, connect it to a PC or a PLC.
□ Connect the balance to a PC using a USB or an RS-232C cable.
□ Connect the balance to a PLC using a RS-232C cable.

□ When connecting the balance with a PLC and the printer or the external display unit, in both
cases you must use RS-232C cables. When the balance is equipped with the GXA–03 special
option (2nd RS-232C cable, insulated type), connect the PLC with a cable to the RS-232C
connector of the GXA-03, and connect the printer or the external indicator unit with a cable to
the standard RS-232C connector of the balance.
