Replacing the RS-232C interface with this option, current loop output, 3-relay outputs
and 1-control input can be used with the RS-232C interface of this option.
RS-232C functions are the same as the RS-232C interface described in "13. RS-232C
Interface".
The solid state relays output the result of comparison.
The control input can control the indicator from an external terminal just like the front
panel key operations.
Set the external control function at F15 of the F-Functions.
When connecting the function pin and the common pin, the indicator makes the action.
Keep a signal width of more than 100ms for the On-time and Off-time.
