CrossPoint 450 Plus and MAV Plus Switchers • Quick Start
PRELIMINARY
Installation of multiple BME system
Rack mount the switcher BMEs.
Step 1 — Numbering the BMEs
Each BME must be set to a unique address of 0 through 5.
BME address switch — To set the BME address, press the
+ and - buttons on the BME Address switch on the rear
panel of the switcher BMEs, as shown at right.
N
Addresses 6 through 9 are invalid.
The addresses used in the system must be sequential
with no skipped numbers.
Sync BMEs cannot be set to address 0
N
BME 0 is the controlling unit. All control
communications and front panel operations shuld be
made through BME 0 only.
Step 2 — Daisy chaining the BMEs
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.
BME COMM interconnect ports — Connect the fi rst daisy chain
from BME 0’s BME Comm Out connector to the nearest BME’s
BME Comm In connector as shown at right. In a rack whose
BMEs are arranged so that their physical location matches the
BME address numbering, this would be BME 1. But since not all
systems are confi gured alike, call this module BME n.
Connect the next RJ-45 cable from BME n’s BME Comm Out
connector to 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 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.
I/O Connections
Step 3 — Inputs
a. Video and sync BMEs — Connect a single plane of video or sync, as appropriate to the BME, to
the BNC connectors on the video and sync BMEs for each input.
N
Each BME supports one video or sync plane only. See fi gure 1-1 in chapter 1 for an example
confi guration.
b. Audio BME — Connect balanced or unbalanced stereo or mono audio inputs, as appropriate to
the BME type, to the 5-pole (stereo) or 3-pole (mono) captive screw connectors.
