DIP Switch Setting
Section 3-1
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 Controller 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.
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 trig-
ger 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).
