The OPN 2001 is a small reader designed for Data-Collecting purposes.


How do I upgrade the firmware?

You can find the latest firmware version on the main web site: http://www.opticon.com -> Service & Support -> Download software -> OPN 2001 -> RBBfirm.zip

Extract this zip file. This will leave you a RBBVxxyy.hex file.

Connect the OPN 2001 to the PC. Find out which COM port it has been assigned, by using the "Device Manager".

Then use the Appload application to transfer the firmware file to the OPN. Configure Appload to use the right COM port and then open the firmware file. The upgrade will now start.

The buzzer doesn't work anymore

The OPN 2001 can be configured that the buzzer can be turned on and off by using the scan button. When the scan button is held for ten seconds, the buzzer will be turned off (or on).

This feature can be disabled using the OPN's parameter "Beeper toggle" (0x55).
