Forcing a Hardware RFS
Pin 2 of serial communications D-type connector X3 is for use as a hardware method of
forcing a return to factory settings. It may be used when it is not possible to perform an OFF
or RFS command. Such a situation may be switching to RS485 mode but having no RS485
interface on the controlling PC, forcing an RFS command will allow you to return to RS232
operation.
To force a hardware RFS follow the procedure detailed below, note you will loose any
program in memory and system variables will return to their default values:
1. Turn off drive HV and +24V.
2. Connect X3 pin 2 (MODE input) to X3 pin 3 (0V).
3. Turn drive +24V on (and HV if required). On power-up, any program present in
memory is cleared and ALL system variables are set to their initial factory default
value.
4. Establish RS232 communications using Easi-V and type in 1SV and press [Enter]
to store the changes.
