Chapter 2: Installation
Connecting a hybrid cluster
Connect a hybrid cluster (a minimum or standard display module and up to eight
detector modules) using ribbon cables for adjacent modules and the SNET+
connectors for distributed modules within the cluster, as shown below. The
maximum cable length between modules is 1,200 m (4,000 ft.).
In this installation type, each group of adjacent modules uses a shared power
supply (connected to a single module) and each of the distributed modules
requires a separate power supply. End-of-line termination is required for all
unused J3 and J5 connectors on the backplane PCB.
