External Trigger Operation
External trigger operation enables an external device to control scan-
ning. External trigger is controlled by applying an external trigger
signal to the CTS input (with external triggering enabled). When
active, this s ignal cause s scanning t o begin just as if the scan ner’s trig-
ger were depressed. Scanning continue until a label is decoded or the
external trigger signal is deactivated.
In the event of a decode, the trigger signal must be deactivated for a
minimum of 50 milliseconds before another scan can be attempted
(“tying” the trigger signal active does not cause continuous scanning
and decoding).
When EXTERNAL TRIGGER(+) is scanned, scanning begins when a
high level input is applied to the CTS input. Conversely, when
EXTERNAL TRIGGER(-) is scanned, scanning begins when a low
level is applied to CTS. When CTS is not connected, it is treated as if a
high level is applied. The voltage levels given are at the modular con-
nector. If an RS232 converter pod is used, then the levels are inverted.
