Connecting a distributed cluster
Connect a distributed cluster (a minimum or standard display module and up to
eight detector modules), using the SNET+ connectors on the backplane PCB, as
shown below. The maximum cable length between modules is 1,200 m
(4,000 ft.).
In this installation type, each module requires a power supply (see “Connecting
the power supply” on page 26) and an end-of-line termination to be installed onto
the unused J3 and J5 connectors on the backplane PCB.
