Hand Held Products 4410 manual Serial Triggering

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).
