Verifying Scanner Operation
External Power Supply – If you have a Duet scanner with the
optional external power supply, you can verify scanner operation
prior to installation to ensure the scanner is fully functional.
Follow these procedures to verify scanner operation if you have the
optional external power supply. (Reference Figure 7):
1. Plug the scanner end of the interface cable into the
rear of the scanner until it clicks into place.
2. Plug the DC plug (of the AC/DC power supply) into
the DC receptacle on the interface cable.
3. Plug the AC/DC power supply into a functional AC
power outlet.
4. The scanner will run a Power-Up Selftest.
Passes Selftest – The scanner should emit four successive tones
indicating that it has passed the Power-Up Selftest routine. The LED
indicator lamp flashes brightly once. The LED then transitions to a
dim condition, indicating the scanner is ready for operation. Verify
operation by scanning a few bar codes.
NOTE
Since the scanner is not connected to a host terminal, it may read
only one or two bar codes before it must be reset. This is normal
because some terminal interfaces require the scanner to store bar
code data until the POS terminal signals that it is ready to receive
the data.
Fails Selftest – If the scanner powers-up, but the LED lamp begins
flashing and the speaker repeats a series of tones, go to the section
titled, Problem Isolation.
