A.5 Cables and Connections
Once the CLO-10s and the accompanying equipment have been mounted, the user must properly
attach all required cabling. Referring to Figure A-10 and Figure A-11, interconnection between
all equipment in the Daisy Chain Redundancy System is accomplished as follows:
• Connect Redundancy and Traffic Unit(s) using the High Speed Bus Cable, fabricated and
supplied by CEFD. This cable connects to the DB-25F J2 Redundancy connector on each
unit, and consists of as few as (2X) DB-25M connectors (for the CEFD P/N
CA/RB0014-1-U2 1:1 Cable, shown in Figure A-10) to as many as (13X) connectors (for
the CEFD P/N CA/RB0014-12-U2 1:12 Cable, shown in Figure A-11). There will be only
as many DB-25M connectors as is required for the specific 1:N Redundancy system.
IMPORTANT
The unit’s assignment number must match that of the numbered DB-25
connector on the High Speed Bus cable (CEFD P/N CA/RB0014-XX-U2).
• Using CEFD-supplied BNC patch cable CA/BNC75OHM, first connect the inputs and
outputs between the Redundant Unit and Traffic Unit #1; then, connect the inputs and
outputs between each Traffic Unit subsequent in the redundancy chain.
• For the interfaces between the CLO-10, modem, and the up and down converters, use
standard off-the-shelf 75Ω BNC male-to-BNC male patch cables, supplied by the user.
As an alternative to using off-the-shelf patch cables, the user may purchase IF Cable
PL/0813-4 (75Ω BNC male-to-BNC male, 4’) from Comtech EF Data; this cable can be
ordered at the same time the order is placed for the CLO-10 Daisy Chain Redundancy
System.
A.5.1 75Ω Load in Redundant Unit
As shown in Figure A-10 and Figure A-11, a 75Ω load (CEFD P/N CN/CXLBNCTM01) must
be installed in the J5 (“To U/C”) port on the Redundant Unit’s IOM. This load is needed to
terminate the splitter on the IOM.
