2.1 NIC-500N
A NIC-500N is a variation of the NIC that can be used to run up to 2 Noggins simultaneously.
Noggins are available in 4 center frequencies: 100, 250, 500 and 1000 MHz. Multiple NIC-
500Ns can be connected together, to run any number of Noggin systems; this is called daisy-
chaining.
On the long side of the NIC-500 (opposite side to the power and odometer connections), there
are two Noggin ports and a serial port (Figure 2-4), described below:
•
Serial port – used to connect a GPS receiver. The GPS receiver can receive power from
this port, if power out is enabled. For more information, see
•
Noggin Ports – there are two numbered ports available to connect up to two Noggin
sensors. The NIC-500N can be run with only one Noggin, which would be a single
channel system.
