Manual Identification
Neuron ID of a device can also be entered manually through a commissioning or service tool. Neuron ID
should be located on the Echelon chip of the device being commissioned.
Figure 8 shows an example of a Manual Neuron ID request made through a commissioning tool.

Tips And Things You Need To Know
If the heartbeat is lost, the module will release the network sensor value for the Room Temperature
(nviSpaceTemp) and the Outdoor Temperature (nviOutdoorTemp);
The heartbeat parameter of a Tridium front-end should be set at the slowest configuration possible so
that nviTimeStamp updates correctly;
With any LNS Tools, nviTimeStamp should be set to refresh everyday or on power-up;
Viconics recommend to use the provided Viconics format files as stipulated in the snivet per model table
