2.2 NIC-500P
The NIC-500P can run up to 2 pairs of pulseEKKO PRO transmitters and receivers
simultaneously. pulseEKKO PRO antennas are available in 8 center frequencies: 12.5, 25, 50,
100, 200, 250, 500 and 1000 MHz. Multiple NIC-500Ps together can be connected to run any
number of pulseEKKO PRO antenna pairs; this is called daisy-chaining.
On the long side of the NIC-500 (opposite side to where the power and odometer connections
are), you will find 4 pulseEKKO ports and a serial port (Figure 2-5), which are 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 Section 3.3.
•
pulseEKKO antenna ports
– there are four numbered ports available to connect up to
two pulseEKKO transmitter and receiver pairs. If you are using low frequency antennas,
you will need to use fibre-optic converters to convert the fibre-optic cable to the 15-pin
antenna port input (Figure 2-6). The other end of these cables will run to the respective
transmitter or receiver. The NIC-500P can be run with a single transmitter/receiver pair
if desired, which would be a single channel system.
