3.1.3 NIC-500X
The NIC-500X allows for the connection of up to eight pulseEKKO PRO transmitters and
receivers simultaneously. The key distinction compared to the NIC-500P is that any
combination of transmitters and receivers can be connected to the NIC-500X. For example,
various configurations include 1 transmitter and 7 receivers, 1 transmitter and 5 receivers, and 4
transmitters and 4 receivers.
There are many combinations possible, but the following rules must be followed:
•
Transmitter-Receiver
pairs on ports ‘1’ and ‘2’ and ports ‘3’ and ‘4’ must have the same
System Configuration settings under the GPR tab ( Section 4.3.3). If the settings are
different, then the second
pair must be on ports ‘5’ through ‘8’
•
There must be at least one receiver in ports ‘1’ to ‘4’
A fully loaded NIC-500X (with eight connections) is shown in Figure 3-7. See Section 8.2 on
compatibility.
Once completed, move on to Powering up in Section 3.4.

3.2 Connecting all components
– multiple NIC-500s
If multiple NIC-500s are connected (daisy-chaining), one NIC-500 must be designated the
“Master”, and the other NIC-500s will be “subordinates”. The Master NIC-500 will have the main
power supply plugged into it. As well, if a GPS and/or an odometer are used, these must also
be plugged into the Master NIC-500. When stacking NIC-500s on top of each other, the Master
NIC-500 should be on the bottom. This way, the link cables will not cross over one another.
