Serial Communications Connection
Serial communications connection is made to an RJ45 connector labeled M-LINK on the back of the
scanner. The Modbus Scanner uses the PDA1485 RS-485 adapter to interface with other Modbus
devices and the PDA8485 RS-485 to USB converter or PDA7485 RS-232 to RS-485 converter to connect
to a PC. The same port is used for interfacing with all expansion modules (e.g. external relays, digital I/O).
Use the PDA1200 meter copy cable for scanner-to-scanner interfacing for cloning purposes (i.e. copying
settings from one scanner to other scanners).
