We have a VIZIA RF + network with 120 nodes. The reliability with the Vizia RF + serial interface module is very poor. Some nodes work 80% of the time and other nodes work 2% of the time. We are using the installer tool v 184.108.40.206 and the think stick adapter as the primary controller and have performed the following steps in the order shown below as discussed in the Leviton Tech memorandum Vizia RF + advanced menus document dated 6-26-08
Step 4.2 go to advanced /RS232 Setup and confirm all devices in the network have been associated to the serial interface
Step 3.3 Network Rediscovery at -6db for all nodes
Step 3.4 Network Update Controller for all controllers in the network
Step 3.9 Update Routes for all nodes
Hop Count and link quality function from Vizia RF + serial interface module to all nodes and the hop count ranged from 1 to 3 as shown on the sample screen shot on the attached file.
Please let us know which way to proceed to improve reliability with Vizia RF + serial interface module.
