Configuration Exceptions for USB

Read Cycle Mode

By default, the Imager operates in Continuous Read Mode. If the Imager is configured using Data Matrix symbols, the read cycle mode should be the last item changed before saving the configuration settings and beginning operation. This is because all read cycle modes other than Continuous Read Mode require a trigger event. In USB, a trigger event can only be initiated by serial command. To send a trigger command the Imager, the host application must establish a connection with the Imager's Microscan HID interface and send the trigger command in a Microscan HID Report.

The following read cycle conditions are required for USB MS-4:
Serial Cmd:
<K200,read mode>
Default:
Continuous
   
Options:
0 = Continuous Mode
1 = Coninuous Read 1 Output Mode
 
2 = Level Mode
3 = Edge Mode
  
 
4 = Serial Mode
5 = Serial and Edge Mode

Important:

  • To use Level Mode, you must enable Undelimited Start Trigger Character <K229> and Undelimited End Trigger Character <K230>.
  • To use Edge Mode, you must enable and use the Undelimited Start Trigger Character <K229>.
  • To use Serial Mode, you must use the Delimited Trigger defined by <K201>, or enable and use the Undelimited Start Trigger Character <K229>.
  • To use Serial and Edge Mode, you must use the Delimited Trigger defined by <K201>, or enable and use the Undelimited Start Trigger Character <K229>.
