It's possible that the beeper has been disabled using the beeper toggle feature. The beeper can
be disabled or enabled without using a computer if you hold the large key for more than 10
seconds. To re-enable a disabled beeper, try holding this key for about 10 seconds. The OPN
will sound a tone when the beeper is re-enabled.
I'm trying to integrate the OPN2001 ActiveX control with my Silverlight application, but when I
try to create the opnCtl object, I get an exception. What's going on?
The OPN2001 ActiveX control doesn't expose an Automation API, which is why the exception
occurs. See the MSDN article about using Automation
here
.
How can I communicate with the OPN2001 in my Java application?
You could utilize the native OPN2001 library via JNI, making a JNI wrapper for the exposed
functions.
Will applications written for the OPN2001 work with the
OPN2002
or
OPN2003
?
Yes, if the OPN2001 simulation application - a piece of firmware for the
OPN2002
and
OPN2003
- is installed. The application simulates the behavior and protocol of the OPN2001, making it
compatible with your OPN2001 applications.
Is the serial protocol of the OPN2001 available?
No, we don't release that information. The recommended and authorized way of communicating
with the OPN2001 is via its various APIs.
Is there a way to recover the saved data from an OPN2001 after the clear command has been
sent?
Unfortunately no - the OPN2001 firmware erases the flash sectors where the data was stored
upon executing the clear command. Make sure that the data has actually downloaded before
you issue the clear command!
Is polling optional or required?
Polling is really meant to automatically detect when the OPN2001 has data, and then download
it via a callback function. As such, it's not explicitly required.
The OPN-2001 is a small handheld wireless barcode reader capable of storing up to 10,000
barcodes at a time.
Factory Reset
To factory reset the OPN-2001 please follow the below instructions.
Ensure the OPN-2001 has sufficient charge (at the least the laser should come on with a trigger
press when the unit is unplugged)
Disconnect the OPN-2001 from any USB connections
Press and hold both buttons (scan and clear) for 10 seconds
At the end of the time you will hear a single tone indicating successful reset. While holding the
keys the LED will flash RED (If it flashes any other color you are not holding both buttons firmly
enough).
