The NRM provides a wireless solution of transferring data from RTU to
another RTU within the Distributed RTU Network (DRN). The data can
be any type of information that the RTU has in its database, such as I/O,
soft points, or other information.
The NRM includes a FreeWave radio to handle the wireless data
transmission. The radio utilizes TDMA technology, and allows for
multiple networks (with unique Network IDs and Frequency hop Keys)
to be located in close proximity to each other without experiencing
signal degradation.
The NRM is designed to be plug-and-play and requires no wiring. The
NRM can be installed in slot 1, 2, or 3 in the ROC800-Series 2 RTU.

Depending on the enclosure you choose to surround the node and
protect it from the environment, you may need additional cabling
between the antenna and the connection on the module itself. For
