Serial Triggering - Hand Held Products 4410, 4710 User Manual

Serial Triggering

This provides a means of sending a serial trigger command to start and stop
decoding. When this feature is turned Off , the Imager will not respond to serial
trigger commands. When serial triggering is turned On , the Imager requires a
serial trigger character to activate scanning and decoding. The unit continues to
scan and decode until the Trigger Off character turns off the scanner, a time out
occurs, or a bar code is decoded.
On the "Decimal to Hex to ASCII Conversion Chart" on page 2-36, find the hex
characters you want to use to turn the trigger on and off. Locate the decimal
values for those characters and scan the 2 digits for each one from the
Programming Chart in the back of this manual.
When Serial Triggering is On, the default Trigger On decimal character is 18 (hex
12, DC2), and the default Trigger Off decimal character is 20 (hex 14, DC4).
