BLU- CIF Interface Board

The BLU-CIF Interface Board
simplifies the wiring of all of
the BLU products to the BSS

Audio London Series Digital
Signal Processors. It allows

for Cat5e wiring termination, as
well as, termination to 3.5mm
euro-style blocks. The BLU­CIF accommodates connections
for the BLU-CC, BLU-CP,
BLU-CS, BLU-IR, BLU-SV,
BLU-SV8 or Emtech MSC-C
modules for combining audio in

overflow areas. It is designed
for mounting on the back door

”

IMPORTANT: IF you are using CAT5e wiring termination with the

BLU-CIF, then the RJ-45 connectors need to be crimped to TIA/EIA 568B
Standards (see below) on both ends of the cable. You must crimp and test

the wiring with an approved CAT5 568A/B tester before connecting any
cable between the BLU Products and the BLU-CIF Interface Board.

Failure to crimp wiring to the correct standard could possibly lead to
component damage.

IMPORTANT: If you use the RJ-45 block for connecting the BLU-CC,
BLU-CP, BLU-CS, BLU-IR and BLU-SV(8), then do not use any of the

3.5mm euro-style connectors for these accessories. If you are using the

BLU-IR Infrared Sensors for combining audio in overflow areas, then you
have a choice to use either the RJ-45 connections in this block or the 3.5mm
euro-style connectors. Wiring the BLU-IR Infrared Sensors into the 3.5mm
connectors will be covered later on in this document.

A legend for the BLU-CIF RJ-45 connections has been silkscreened on the
Interface Board next to the corresponding block of connectors.

BLU-CIF 3.5mm Euro-block Wiring Instructions

The 3.5mm euro-block connectors have been provided for easy installation
of the BSS Audio equipment into older buildings with existing analog
wiring. Connectors for the BLU-CC, BLU-CP, BLU-CS and BLU-SV have
8-pins, and are located behind the RJ-45 block on the top half of the board.

A remote control can be used for controlling the volume of the various
microphone inputs in the cultural hall. When wiring for a remote application
wire to IN5 thru IN9, Ref and GND on CC1A, CC1B and SV2.

BLU-CIF / MSC-C Wiring Instructions

Some existing buildings already use Emtech
MSC-C modules to provide chapel audio for the
cultural hall and overflow areas. The BLU-CIF is
designed to allow these existing modules to
interface with the BSS Audio DSP. Located
through the middle section of the CIF Board are
three 4-pin euro-style connectors. Each
connector has identification and wiring
designations silkscreened below it.

There are no switches associated with the C switch connectors on the new
version of CIF board. IN11 and IN 12 are bit encoded with 4 bits each. C­SW1 and C-SW2 map to IN11, and C-SW3 maps to IN12. When either a C
switch or IR get wired to the CIF board, the device will be automatically
detected. The pin-outs on the C switch connectors are:

connectors. Wire each IR sensor to its’ corresponding 4-pin connector using

BLU-CIF PWR RELAY & OF1 RELAY Wiring Instructions

There are two separate relay
connectors on the top right
side of the CIF board. The 2­pin PWR_1 connection is used
to power on external
equipment. This connection
will supply +24VDC @
100mA on the “+24” pin
when lo

ic output 6 on the

DSP is triggered. The voltage from the +24 pin is typically connected to an
external power relay coil, which will then switch 120VAC on to the external
equipment. The PWR RELAY output is thermo-fuse protected, so it will
stop supplying power when the +24 pin exceeds 100mA. The circuit will
reset automatically once the load is disconnected.

The 4-pin OF_1 overflow relay connection is a 2-pole “dry contact” that is
normally open. These contacts will close connecting the “+” (pin 1) to the

5

“+” (pin 3), and the “-“ (pin 2) to the “-“ (pin 4), when output port 5 on the
DSP is triggered. This is typically used to switch speaker level signals, so
an overflow room can be fed directly from an amplifier without needing its
own dedicated amplifier channel.

Connecting the BLU-CIF to the BSS Audio London Series DSP

The BLU-CIF ships with two pre-fabricated 12-conductor cables. Each
cable has 3.5mm connectors on both ends. On one end, the 3.5mm
connectors are color-coded green and black, so they match up with either the
Control Port 1 (Black) connector or Logic Inputs (Green) connector on the
upper right quadrant of the CIF Board.

Control Inputs Connector

Logic Outputs Connector

Control Inputs connector mates with the cable
with Control_Port1 (Black) connector.

Logic Outputs connector mates with the cable
with Logic Inputs (Green) connector.

The 3.5mm connectors on the opposite end of each cable are orange. They
match the color of the mating connector on the back of the DSP and are
labeled “top” and “bottom”, so make sure that the cables are connected
correctly on the DSP side. Another way to remember : Black on the

board goes to the top connection on the DSP, and Green on the board
goes to the bottom connection on the DSP.

BLU-CIF Power

Power Jack

The power jack for the BLU-CIF is located on
the bottom left side of the board; below the RJ­45 block. The BLU-CIF is shipped with a
universal desktop power supply that plugs into
the power jack, and supplies it with 24VDC @

1.67A. The power cord on the supply plugs into
a standard 120VAC outlet.

OLDER ACCESSORIES & THE NEW CIF BOARD

When using the new version of the BLU-CIF board with older versions of
the BLU-CC, BLU-IR or the MSC-C switches there will be some additional
wiring that must be done on the new BLU-CIF board for these to work
properly with the old template. No additional wiring needs to be done when
using the older versions of the BLU-CP and BLU-CS with the new BLU­CIF board. When using the new BLU-CC2 with the new BLU-CIF board,
new templates are required but not additional wiring. Contact BSS Audio
for new templates.
