Bypass Mode - Enabling Action on 254 Code
When 3.x Tags cannot determine the Reader ID, they transmit back
a 254 code in place of a Reader ID. In default mode, the Reader will
not report or act on this code. It will only report Tag messages which
include its own ID number. A Wiegand Reader can be set to report
messages with both its ID number and code 254. This is useful at
sites where vehicles travel quickly over a Road Loop Antenna and
the Tags may not have time to resolve the Reader ID number.
Step 1:
At the “Enter:” prompt, type a dollar sign ( $ )
The Wiegand Reader will respond with “ReaderID 254
ON”
IMPORTANT!
Do not turn on the bypass mode on a
Reader that is within the range of another Reader. This will
cause crosstalk.
Step 2:
Turn off the bypass mode by pressing the Spacebar until
the “Enter:” prompt appears and then typing the dollar sign
( $ ).
The Wiegand Reader will respond with “ReaderID 254
OFF”
The bypass mode is stored so that the Reader will continue to report
254 messages even if it has been powered off and powered back up.
