Infrared (IrDa) to RS232 converter cable

A special cable with an optical infrared (IrDa) interface is needed to connect
REF 542plus to a serial port of a PC. This cable is available from ABB.

Null-modem cable

If there is no HMI applied or a direct connection to the base unit is preferred, a
standard null-modem cable can be used to connect the base unit via the so called RS
232 service interface (X72) to the PC.
