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.
The TriCoder beeps, but nothing appears on your
computer screen…

Recheck the installation instructions – Chapter 5; TriCoder Connection –
to make sure all cables are properly connected. If you are connecting
directly to a serial port on a PC, use the following checklist:
1. What kind of computer and port are you plugging into?
•
A 25 pin female port is a parallel port.
•
PC – Male 9 pin port. A 9 pin female port is a video port.
•
Laptop COM ports are almost always 9 pin male.
2. What cable are you using?
•
F34 – 25 pin null-modem cable
•
F36 – 9 pin female cable
•
If you have a 9-pin COM port and have the F34 cable, use a 9 to 25
null modem adapter or get the right cable (F36).
3. What Computer Interface is the TriCoder set for?
•
“3” is the correct setting for RS-232
