2. Introduction
Module Slots and Rear Connectors
If the NV8288-Plus router is used as a standalone router, only the 6 local outgoing signal connec-
tions are used. If the router is connected to another NV8288-Plus router, each expansion connection
send signals to the connected router, as follows: output slot 1 sends outputs 289–294 to the con-
nected router, output slot 2 sends outputs 295–300 to the connected router, and so on, up to 576.
Similarly, the connected router sends outputs to the local router in the same manner, doubling out-
puts. Inputs are also doubled, so that the two routers have a combined total of 576 inputs and 576
outputs.

For information on installing cards in modules slots, see Installing Active Cards on page 33.
The rear of the NV8288-Plus (Figure 2-7, next page) features non-interchangeable backplanes con-
taining 288 I/O DIN 1.0/2.3 connections for receiving signals and 288 DIN 1.0/2.3 connections for
distributing signals, plus 48 expansion connections for sending signals between two connected
NV8288-Plus routers. By connecting two routers you can receive and distribute up to 576 signals.
Note that the outputs and inputs are numbered from right to left because the router is being viewed
from the rear.
