Network Analyzer (available on CNMSX-PRO only)
To assist with troubleshooting, the unit contains Crestron’s patent-pending network
analyzer to continuously monitor the integrity of the Cresnet network for wiring faults
and marginal system performance or other network errors. For more information on
how to use the network analyzer, refer to the SIMPL™ Windows
help file and use
the index to search for "Network Analyzer".
