Troubleshooting
A reader installed in Wedge mode (external or internal) doesn't beep three
times when you power up your system, or the keyboard locks up, or you
get a "keyboard error" or "301" message.
Check the cable connections to make sure everything is plugged in securely.
With a PC, make sure the keyboard cable is plugged into the keyboard port
rather than the mouse port. If on a Mac ADB, be sure the tagged end of the
Y cable goes to the ADB port.
If, after checking the connections, you still have a problem, your computer
and keyboard combination probably doesn't have enough left-over power to
drive the bar code reader also. Disconnect the scanner from the WDP Reader
and reboot your system. If the system boots correctly when the scanner is not
attached, you solve the problem by ordering a 5-volt external power supply
(feature code F10).
If the system still doesn't boot correctly with the scanner disconnected, a
Worth Data regulated power supply (don't use someone else's power supply or
you will damage the reader)- will probably still correct the problem. If you are
using a USB reader and there many devices, you may need either a power
supply on the WDP, or you may need a powered USB hub device.
The reader won't beep when reading bar codes
Recheck all the connections using the installation section as a guide. Try
reading a known good bar code - the test label on page 18, following the steps
for scanning in Appendix K. If you're trying to read Code 39 bar codes with
leading spaces (such as the Barpad on page 27) and have enabled Accumulate
Mode, those bar codes will not be transmitted to your computer until you read
a bar code without a leading space. Try reading the Test Label on page 18 as
an example of a known good label.
Reread the configuration section and make your bar code type is enabled.
Switch a wand to the Magstripe Port and try again. If it works in the
Magstripe port, the wand port is probably jumpered for laser.
If the read failure is on Interleaved 2 of 5 codes, make sure the data length is
the same that you selected on the Reader Setup Menu. Be sure you don't have
the check digit enabled for Code 39 or Interleaved 2 of 5 if you're trying to
read data without check digits.
