Trouble Shooting
Our Barcode Scanners are simple to install and use.
Most operational issues can be attributed to:
INCORRECT INTERFACE CONNECTION INCORRECT
CONFIGURATION SETUP POOR BARCODE QUALITY
GENERAL PROCEDURES
1. First, make sure the scanner is firmly connected to the host computer, when
attached correctly, the scanner will emit one long beep. When the trigger is
pressed, LED will flash.
2. Once the power is on, try scanning some sample bar codes from this user’s
guide. The scanner should beep and the LED should flash to indicate a
good read in the default configuration. If reading the bar code does not
result in a good read, there may have been a problem with the scanning
technique or the interface configuration setting. Reset the scanner to
default.
3. If the scanner indicates a good read, but there is no output of data to the
monitor, please check the cabling connection.
KEYBOARD INTERFACES PROBLEMS
In general, the Keyboard Wedge interface is trouble free, but there is still
something to check in the event of a problem:
Do you have the correct cable?
Most computers use an XT/AT-compatible keyboard. Be sure you have the
proper cable for your computer.
Does the keyboard work?
Since the keyed-in data from keyboard must pass through the decoder, the
cabling connections are correct if the keyboard is functioning.
Can your computer accept the data fast enough?
Your computer’s BIOS has a feature related to keyboard typing speed. Try to
set the Intercharacter Delay feature to stimulate the keystroke entry speed.
