You pull the trigger, the
red scanning beam
turns on, but you
cannot successfully scan
a bar code.
Try these possible solutions:
• Make sure that the SR31T is configured for the
symbology you are scanning.
• Make sure that the SR31T is at the appropriate
scanning distance from the bar code. Move the
SR31T closer and further away to find the
appropriate distance.
• Make sure that the SR31T is configured for the
type of bar code (1D, 2D) you are scanning.
• Make sure the bar code you are trying to scan is
not poorly printed or too small. Scan a known
good bar code to make sure that the SR31T is
working correctly.
For more information, see Scanning Bar Codes in
Chapter 2.
You scan a bar code and
the status light turns
on, but the SR31T does
not beep.
The SR31T may be configured not to beep (beep
duration / volume / frequency / number settings).
You scan a
configuration bar code
and the SR31T beeps six
very fast beeps.
The SR31T does not recognize or support the
configuration bar code you scanned.
You scan a bar code, the
SR31T beeps once, and
the status light blinks
green once, but the data
is not transmitted to the
host computer.
Try these possible solutions:
• Make sure that your data collection application
is set up to receive data from the SR31T.
• If you are using an RS-232 cable, make sure that
the serial parameters on the SR31T match the
serial parameters of the host computer. The
default serial parameters for the SR31T are:
57600 baud, 8 data bits, no parity, and 1 stop
bit.
You cannot scan the
Firmware upgrade bar
code on your computer
screen.
