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.

On the left side of the
BLU-CIF Interface
Board is a 2 X 4 block
of RJ-45 connectors
for terminating the
BLU products via
Cat5e wiring. The
BLU products connect
in this order (left to

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.
