OPERATION
Operation
The NRD1 is a basic managed
network relay. The device does not
have any direct field inputs. Its
function is to re-broadcast valid M2
or M1B RF packets.
The default mode of operation for
the NRD1 is MONITOR.
In MONITOR mode, the NRD1
simply wakes up pseudo-randomly
every 3-10 seconds and transmits
its ID and internal diagnostic
information. At the end of this
transmission, the NRD1 will go into
a receive mode to check for any
host commands.
The host computer can initiate the
following commands through the r2
Transceiver:
Broadcast: This command will
direct the NRD1 to receive and re-
transmit any local M2 or M1B
messages for a specified duration
(default of 60 seconds)
Change Freq: This commands
directs the NRD1 to change either
its receive or transmit frequency.
