１２ CURRENT LOOP INPUT (AD-8922A-05)
Can receive the current loop output from the weighing instrument. The data received can be output to an
external device such as a personal computer and a printer, using the RS-232C serial interface. The
weighing instrument can not be operated using the AD-8922A keys.
Note: When AD-8922A-05 is installed, the pin assignment (DIN 8-pin) of the RS-232C serial
interface, to connect an external device, will be changed.
Note: The AD-4212C does not have current loop output. Therefore, this option can not be used.
