One or more of my modules is not communicating with the GPM software. What should I do?

There may be a problem with the radio frequency (RF) chip attached to the circuit board. This is a dark green/blue colored chip with a black antenna. Refer to RF Service Procedure Chip and Board Replacement (RFS013) for help in identifying the part.  

To diagnose, perform the following steps:

1. With the GPM program running, identify a module that is communicating normally.  
2. Unplug and remove the batteries from a working module and the module that is not working.
3. Shut down and restart the GPM program.  
4. Remove the RF chip from both modules, being careful to avoid pulling on the antenna.  
5. Switch the RF chips by plugging the RF chip from the working module into the non-working module’s circuit board and the RF chip from the non-working module into the working module’s circuit board.  

If the original working module is no longer working and the original non-working module is now working, this indicates that the RF chip needs to be replaced. Unplug the batteries and return the RF chips to their respective modules.  

If the original working module is still working and the original non-working module is still not communicating, this indicates the RF circuit board needs to be replaced. If neither module works, this indicates that both the RF chip and the circuit board need to be replaced. 

Contact ANKOM Technology for a replacement RF chip (Part #: RF45/#RF45X) and / or an RF circuit board (Part #: 7007). Provide the RF chip number and the network number of your RF Gas Production System when contacting so that the RF chip is programmed properly. The network number could be any of 1-5 and is noted in the upper right corner of the ANKOM sticker on the Base Coordinator (Part #: RF2) on the line following the "N". Refer to RF Service Procedure Chip and Board Replacement (RFS013) for installation directions.
