Rear panel

AC Mains
AC Mains input to the universal switched-mode power supply, operates over a wide range
of AC input voltages from 100V to 240V, 50/60Hz.
Locate
Pressing the Locate switch on the rear of the unit will illuminate the PWR LED on the
front and identify the device within London Architect. Similarly the switch will illuminate
if the device is located from within London Architect.
RS232
Serial port for connection of external control equipment.
Ethernet
The main connection for the proprietary system control network, and for third-party
Ethernet control.
BLU link
The London BLU link is a point-to-point digital audio bus with 256 audio channels at
48K sample rate or 128 audio channels at 96K sample rate. The BLU-100 allows access
to channels 1-48 of this bus, at 48K sample rates. The physical connection is made with
Cat 5e cable from the OUT port of one device to the IN port of another device. The
devices are connected in a daisy chain fashion continuing with the OUT port of one
device connected to the IN port of the next device. Redundancy can be provided by
completing the loop and connecting the OUT port from the last device to the IN port of
the first device in the chain. All devices connected in the London BLU link chain must be
configured for the same audio sample rate.
Analogue Input/Output Connections
There are 12 analogue input connections and eight analogue output connections. The
analogue connections are balanced, on Phoenix/Combicon connectors.
CONTROL INPUTS
Used to connect switches or potentiometers, e.g. BLU-3 selector wallplate (Part no.
Z-BLU-3). Looking at the control port connector (on the back of the unit), there are two
common (ground) connections C to the left of the twelve CONTROL INPUTS and, two
software assignable reference voltage outputs R to the right.
The control ports have two modes of operation: 2-wire and 3-wire.
