Once you read bar code, there is no output on the monitor,
the symptoms may be caused by:
1. Have you set the protocol of RS232 like Baud rate, data bits,
parity and handshaking etc. of a scanner to match to the PC
terminal setting?
Solution: reset the above mentioned RS232 protocol of scanner
to match to PC protocol.
2. Please check if the cable pinout assignment of bar code match
to the pinout assignment of PC terminal?
No power supply to the scanner:
1. Do you connect the right power adaptor to the scanner?
2. Does scanner connect the cable with right pinout which match
to PC terminal?
Are you using the Wand Emulation mode with Code 39 output?
If so, is your decoder set to accept Code 39 data?
Check the scanner's con guration setting to make sure it can accept
the bar code symbology you are trying to read.
Although the cable seems to connect properly, does the scanner
not send data to the host computer?
There are no industrial standards for scanner interface cables, so even
if they look alike and have similar connector, they might not be alike.
For example, cables for Keyboard Wedge and Wand Emulation are
similar, but they are not interchangeable due to different pin
assignments.
Be sure the cable you are using attaches correctly to the matching
connector.
Are you set up for the right Interface?
Are you set up for the right interface? Did you select the Keyboard
Wedge cable but set the scanner for RS-232 or Wand Emulation?
Or did you change the Keyboard cable to RS-232 but forget to set
the scanner interface to RS-232 as well? Set the scanner to its default
settings, then select the correct interface based upon the cable and
input you are using.
Symptom ---- The LED lighting is stuck, and no function at all,
even triggered the scanner.
Solution ---- Set the scanner to default condition, and choose
the right interfaces.
