are powered, the Remotes’ Carrier Detect lights should be green. When the Repeater is unplugged, the
Remotes should lose contact and Carrier Detect should turn red.
“My radio modems have established a solid connection as indicated by the LEDs, yet the application I
am running is not transmitting and/or receiving data correctly.”
In most cases, this is due to an incompatible port setting on one or both ends of the system. Ensure that each
radio modem port setting and the device that it is connected to are set up the same.
It is also possible that the devices are not properly configured to communicate with each other. The quickest
acid test in a situation like this is to try to get the application up and running using an RS232 null modem
cable before deploying the PLR5000 in the field. The PLR5000 essentially functions as a null modem cable.
If the application will not work with a hard wire connection then it will not work with the PLR5000, and the
problem lies within the application or other hardware (such as the computer or PLC serial ports).
