Duplicate Devices
To detect devices set to the same address you can activate the IDNet Diagnostics
- Duplicate Device option. Once activated, there is a trouble in the panel
indicating that you have activated the option. The two devices set to the same
address then come in as a duplicate device trouble for that address.
Acknowledge the trouble and view the point information to determine the
address that the devices are set to and correct the problem.
