Remove any keyboard extension cables or adapters. Plug directly
into the port using the TriCoders keyboard splitter cable to
eliminate the possibility that the extensions or adapters may be
causing the problem.
The TriCoder transmits incorrect or no data to the PC’s
screen…
•
If the TriCoder is transmitting punctuation characters
(!@#$%^&*) when reading numeric bar codes, or transmitting
letters in the wrong case (upper vs. lower), you could have a
Num
Lock, Caps Lock
,
Shift
or
timing delay
problem. Check your
keyboard to see if your Num Lock or Caps Lock is on. Try typing
numbers (the upper row of keys on your keyboard) and see if you
get the correct output on your screen. If you don’t, make sure to
reboot your PC before changing any delays on the TriCoder. See
Chapter 6
;
TriCoder Setup
for details on the
Intercharacter
Delay
setting.
•
If you scan a bar code and correct data shows up on your PC
screen but some is missing, you need to change the
Intercharacter
Delay.
See
Chapter 6
;
TriCoder Setup
for details on how to
change this setting. Test your keyboard after every change made
to the TriCoder setup. If the keyboard does not work correctly,
you will have to reboot before you make another change to the
reader.
•
Make sure you have configured the TriCoder to use the correct
Computer Interface
.
The TriCoder reads one bar code and stops reading
after that…
•
Double-check the
Computer Interface
setting. Selecting
Macintosh
as the interface when you are not physically connected
to a Mac will hang up the TriCoder.
Serial mode troubleshooting
The following problems pertain mostly to TriCoders setup in serial mode – T54.
Using the 5 volt power adapter, the TriCoder does not
beep when turned on…
•
Plug something else into the wall outlet to make sure the outlet is
working or plug the TriCoder’s power adapter into an outlet that is
working with something else. If the outlet is good, either the power
adapter or the TriCoder is not working correctly. If you have more
than one TriCoder, try the other TriCoder with the suspect power
adapter. If you find a problem with either the TriCoder or the power
adapter, call for repair or replacement.
