• Recheck the installation instructions beginning on page 4 to make sure
all cables are properly connected.
• If you're trying to read Code 39 bar codes with leading spaces (such as
the Barpad on page 23) 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 21 as
an example of a known good label.
• If you're using PortKey on an IBM-compatible, verify that the readers
matches the program's COM port, baud rate, data bits, stop bits, and parity
• If you're using your own software to read the serial port, verify that the
problem is not in your software. Run the WDR Serial Test Program
that shipped with your reader and see if it gets any data on the screen
when you read a bar code.
• Use a "null modem" connector to test switching pins 2 and 3 on one or
more serial cables, or use a breakout box to modify your cable(s).
The reader doesn't beep when you try to read your bar codes.

• Try reading a known good bar code -- the Test Label on page 21,
following the steps for proper scanning technique on page 8.

enabled the bar code types you're trying to read.
