End of Read Cycle

4-14 MS-880 Industrial Long Range Scanner User’s Manual

4–Read Cycle/Trig-

Timeout

Definition: Timeout ends the read cycle, causing the scanner to stop reading

labels and send the label data or noread message when the time set in

Timeout elapses (times out), if When to Output is set to End of

Read Cycle.

If in Continuous Read 1 Output, a timeout initiates a new read cycle

and allows the same label to be read again.

With either External Edge, Serial Data, or Serial Data & Edge

enabled, a timeout ends the read cycle and label data or a noread mes-

sage is sent to the host.

With External Level enabled, the read cycle does not end until the fall-

ing edge trigger or a timeout occurs. The next read cycle does not begin

until the next rising edge trigger.

Usage: Typica lly used with Serial or Edge and Continuous One.

It is effective in highly controlled applications when the maximum

length of time between objects can be predicted. It assures that a read

cycle ends before the next bar-coded object appears, giving the system

extra time to decode and transmit the data to the host.
