RS-422/485 Interface of Option, OP-03 | A&D PD4000243 manual

8.6. RS-422/485 Interface of Option, OP-03

The RS-422/485 interface can use command to control the indicator. The interface can read weighing data or parameters or store parameter to the indicator.

The interface can connect max. 32 units and a personal computer in a communication cable.

These unit is specified by address appended to the command.

TS-485 can use 2-wire or 4- wire.

The command and format is the same as the built-in RS-485.
