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.
