LIM0001AA Rev E
The radio is wired for RS485 and Pins 5 and 7 on a board level radio, or Pins 2 and 3 on an enclosed radio (or
one with a DB9 connector) are shorted together.
1. Separate the wires and place the radio into Setup.
2. Change the Setup Port parameter in the Baud Rate tab to Diagnostic Only.
If there is a data source (PLC, RTU, PC, or Terminal Server) connected to the data port data is coming into
the data port while you are trying to access Setup through the diagnostics port.
1. Disconnect the data source and place the radio into Setup.
2. Change Setup Port parameter in the Baud Rate tab to Diagnostic Only.
My transceivers are linked, but I cannot pass data.
Verify that the Baud Rate and Data Parity settings match between devices.
We recently had a bad storm with lots of lightning and my transceiver has not worked since. I have
replaced the transceiver but it still does not link.
Verify that the coax cable or antenna were not damaged in the storm.
I have a new network. My radios are linked but I am not able to pass data. Gas Company X has had
a FreeWave network out here in the same area for a long time and they are not having issues. What
is wrong?
Your network is likely using the default settings for Frequency Key,Network IDs, Minimum Packet Size,
and Maximum Packet Size. Refer to the user manual for the transceiver you added and change your settings
from the default settings.
Most of my sites report in and I can poll, but I cannot poll any of the Slaves that talk back to
Repeater 2.
Repeater 2 is experiencing high noise.
My network has been running flawlessly for the last 2 years. Now, all of a sudden, I have a group of
Slaves that I cannot poll.
A Parallel Repeater has been added/changed in the network and has the same frequency settings and is now
interfering with the other Repeater. Program the new Repeater with a different set of parameters.
My network keeps locking up. If I cycle power on the Master, the network is restored and I can poll
again until the next time the network locks up.
There is a "chatty" Slave in the network. The Slave is not getting acknowledgement of data it sends to the
Master and it keeps trying to resend data to the Master locking out all other communications to the Master.
