Replacing the RS-232C interface with this option, 3-relay outputs and 3-control inputs
can be used with the RS-232C interface of this option.
RS-232C functions and pin connections are the same as the RS-232C interface
described in “16. RS-232C Interface”.
The control inputs can control the indicator from an external terminal just like the front
panel key operations.
Set the external control functions at f13, f14 and f15 of the F-Functions.
When connecting each function pin to the common pin, the indicator makes the action.
Keep a signal width more than 100 ms for the On-time and Off-time.
