HopNet RS-232 Serial ModBus Radio 

Troubleshooting 

Overview 

Introduction 

Troubleshooting the HopNet products is not difficult, but it does require a logical 
approach. It is best to begin troubleshooting at the base station because the rest of the 
system synchronizes to it. If the base station has problems, the entire network will be 
compromised.  

Transceiver Requirements 

For proper operation, all transceivers in the network must meet these basic 
requirements: 
Adequate and stable power 
Secure connections (Power, RF, and Data) 
Proper programming especially Hop Duration and Network Number
