Figure 2-9 — Daisy-chaining BMEs (video BME shown)
2-8 CrossPoint 450 Plus and MAV Plus Switchers • Installation
BME COMM interconnect ports — If the matrix switcher system consists of
more than one BME, the BMEs must be connected together in a daisy chain
using Extron-supplied RJ-45 cables.
a. Connect the first daisy chain from BME 0's BME Comm Out connector to
the nearest BME's BME Comm In connector (figure 2-9). In a rack where
BMEs are arranged so that their physical location matches the BME
address numbering, this would be BME 1. But since not all systems are
configured alike, call this module BME n.

Connect the next RJ-45 cable from BME n's BME Comm Out connector to
b.
the nearest unconnected BME's (BME n+1's) BME Comm In connector.
Continue connecting RJ-45 cables from each daisy-chained module's BME
c.
Comm Out connector to the next module's BME Comm In connector
until all modules are included in the chain. When all of the BMEs are
connected, each of the BMEs in the system is connected to at least one
other BME via the BME Comm connectors.
