Check the Tags
Ensure that the Tags are properly mounted. Tags should not be
mounted in an area that can wake them up when they are not in the
antenna field. They should be mounted in such a way that they can
be activated when they enter the antenna field.
If the Tags are mounted on vehicles, ensure that they are beige.
Black Tags become hotter than beige Tags in direct sunlight and can
warp under extreme conditions.
Check the Reception
If the wake-up field is functioning but Tags are not being read, then
there may be a problem with the reception portion of the system.
Step 1:
Ensure that the Receiver has power.
Step 2:
Ensure that the tag is programmed into the system if
appropriate – i.e., for Wiegand control panels.
Check the Output and Connections to Third-Party Devices
Serial
Step 1:
Ensure that the RS-232 cable is properly seated.
Step 2:
Ensure that the Receiver has power.
Step 3:
Ensure that the communications port settings on the serial
device are correct: that the baud rate matches the rate the
Receiver has been programmed with, eight data bits, no
parity, one stop bit, no flow control.
Wiegand
Step 1:
Ensure that the Wiegand control panel complies with the
SIA 26-bit standard.
Step 2:
Ensure that Data Zero, Data One and Ground are wired to
the Wiegand control panel correctly.
Step 3:
Ensure that the Tags and site code are entered correctly
into the panel.
Step 4:
Ensure that the data is buffered correctly. See Appendix C:
Advanced Wiegand Configuration, page 81.
