BLU- CIF2 Interface Board

The BLU-CIF2 Interface Board
simplifies the wiring of all of the BLU
products to two BSS Audio London
Series Digital Signal Processors. It
allows for Cat5e wiring termination,
as well as, termination to 3.5mm
euro-style blocks. The BLU-CIF2
accommodates connections for two
BLU-CC, two BLU-CP, two BLU­CS, up to five BLU-IR, or up to seven
BLU-SV / BLU-SV8 plus Emtech
MSC-C modules for providing audio
in overflow areas. It is designed for

BLU-CIF2 Cat5e Wiring Instructions

mounting on the back door of a 19”
rack.

IMPORTANT: IF you are using CAT5e wiring termination with the

BLU-CIF2, 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-CIF2 Interface Board.

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

On the left side of the
BLU-CIF2 Interface
Board are two 2 X 4
blocks 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 blocks for connecting the BLU­CC, BLU-CP, BLU-CS, BLU-IR and BLU-SV(8) modules, 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 their
blocks 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-CIF2 RJ-45 connections has been silkscreened on the
Interface Board next to the corresponding block of connectors.

BLU-CIF2 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

2

8-pins, and are located behind the RJ-45 blocks on the top half of the board
for DSP1, and on the bottom half of the board for DSP2 .
