3.1.2 Data-send mode
In the single label read mode only, you can select from the two data send modes
(OK/NG output on trigger) described below: In the multi-label read mode, you can
only select the “send after reading” mode.
• Send after read
The unit outputs the communication and OK/NG signals after a successful read
(trigger output turns on as many times as the preset decode count). This is the
same operation as in the time chart described in “3.1.1 Scanning method”. Nor-
mally, this is the method you should use.
• Send at trigger input
The unit outputs the communication and OK/NG signal when the trigger input turns
off (or the preset input time has passed if one-shot signal trigger is selected).
