6. COMMUNICATION SPECIFICATIONS

The AD-4212C series can communicate interactively using RS-232C.

The AD-4212C series can continuously transmit the weighing data. (Approx.10 times/second* to 50

times/second)

The AD-4212C series is DCE. The AD-4212C series can connect directly to the RS-232C terminal of a

personal computer by using the accessory RS-232C cable.
