PAR-1 Option
This option replaces the standard Ethernet-interfaces for PC control of the test set with a parallel port. This is required when the binary extension device CMB IO-7 is run jointly with the CMC 256plus or if connecting to a CENTRONICS port of a PC is still preferred.
If this option is selected the extension of the test set with the option LLO-2 is not possible, also the CMIRIG-B accessory and GOOSE messaging are not supported.
