Rs-422/ Rs-485 / Relay Output (Op-04) - A&D HW-10KGL Instruction Manual

17.3. RS-422/ RS-485 / Relay Output (OP-04)

Replacing with the standard RS-232C interface, the RS-422/ RS-485 interface can
connect up to 16 scales and control them from a computer.
The RS-422/ RS-485 interface has the following two modes.
