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 or 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 acknowledgment of
data it sends to the Master and keeps trying to resend data to the Master locking out all
other communications to the Master. This is typically caused by a bad signal from the
Slave to the Master. Verify line of sight, antenna direction, and noise levels at the
Slave.
I installed a new Slave in my network, but I cannot get it to link. The CD light is solid red
and the CTS light is blinking red.
This is either an LOS (Line of Sight) issue or settings issue.
I have a site that used to perform flawlessly. Now I cannot reliably get data from the
RTU at this site.
Antenna reflected power is causing a problem. Reflected power may be caused by
defects or damage in the antenna, cabling, connections, etc. Verify that the cabling,
connectors, and the antenna are connected correctly and have not sustained any
damage.
When I connect directly to my RTU I am able to poll data successfully. When I add in
the radios, I cannot get any data from my poll.
A baud rate above 38,400 may need a flow control line connected.
