A&D AD-4402-03 (OP-03): an extra RS-422/485 serial interface for the AD-4402 weighing indicator. Half-duplex RS-422 (4-wire) or RS-485 (2- or 4-wire), up to 32 units on one line, 600 to 38,400 bps.
Description
The AD-4402 batching indicator has a built-in RS-485 port and up to three option slots. The AD-4402-03 (OP-03 in the A&D manual) adds a second RS-422/485 port that uses the same command and data format as the built-in one, so a PLC, PC or remote display can talk to the indicator over long cable runs.
