DIP Switch Setting
Trigger Input
The ID Controller is provided with a trigger input that informs the Controller when
to start processing the DC. After receiving a command from the host controller,
the ID Controller waits until the conditions of this trigger input are satisfied, and
then starts communications with the DC.

Note Even if there are changes to the trigger input status while the ID Con-
troller is processing a command, processing is not suspended.
The condition of the trigger input can be specified to be L level (OFF) or H level
(ON) by using a DIP switch.
(a) (L level active)
(b) (H level active)
(c) (Leading edge active)
(d) (Trailing edge active)
When the auto command is used, the ID Controller waits for the DC approach
after the trigger input has become active. Consequently, the Controller does not
perform Read/Write processing even if a DC approaches before the trigger input
becomes active.

*The ID Controller does not perform processing even when a DC approaches in
the trigger input wait state.
Note When the trigger input is not used, set the trigger condition to L level, and open
the TRG terminal (set pins 1 and 2 of DIP switch 2 to the OFF positions).
