Fault finding
19-11
Tx LED flashing
If the Tx LED is flashing but there is no transmit at the antenna, have
you fitted the RF module?
Solution : if the RF module is fitted, check the connections between
the module and the antenna. The reading head may be broken but
this is highly unlikely.
Tx LED not flashing
If the reader is not being polled then this is almost certainly because
it has not been configured in the Software, or the commands to
configure it have not been downloaded.
Solution : you must check the configuration of the reader by
generating a system list in the Software. Amend the Access Point
record if necessary and download the data to the Controller. To do
this, the comms must be working.
Are the comms working?
There are two types of configuration to consider:
•
Systems with one or two controllers where the PC is connected
directly to one controller.
•
Systems with a Comms module (and more than two
controllers) where there is a connection from the PC to the
Comms module and from the Comms module to each
controller on its branch. For this configuration there are two
comms paths to fault find.
There is an On Line or Off Line message at the bottom of the PC
screen which shows whether the PC is communicating with either the
first Comms module or the first controller.
Mistakes in connections are almost always the reasons for comms not
working but some other things are also worth checking:
Is the correct software running?
If a Demonstration version is loaded it will not go On Line to the
controllers. The Off line message will show at the bottom of the
screen.
Is the correct Comms module fitted?
If the system has over 64 doors or 10,000 cards, it requires a 4235
Comms module as the first in the system. If a 4230 is fitted instead,
the software will not run with the comms.
