INSTRUCTIONS FOR
INSTALLATION AND OPERATION
MODEL V21 ODA-B DISTRIBUTION AMPLIFIER
1. INTRODUCTION
This manual covers the installation, operation, and
maintenance of the Model V210DA-B Distribution Am-
plifier. This unit should be installed by a qualified
technician using approved materials and wiring prac-
tices in accordance with national, state, and local wiring
codes. Read these instruction through completely before
attempting installation.
The V210DA-B Distribution Amplifier provides a
maximum of six video outputs each equal to the single
video input to be used for operation of other video
equipment. Circuitry with individual and isolated com-
plementary transistor pairs provides power for several
75ohm loads, Refer to Figure 1.
Characteristics include AC coupling (for operation with
both AC- and DC-coupled cameras), color compatibil-
ity, and a broad frequency response. The V210DA-B is
available in two input voltage configurations, 120 VAC
and 230 VAC (Model V210DA-B-230). The term
V210DA-B is used throughout this manual to refer to
both models unless specifically stated otherwise.
Model V210DA-B is housed in a sturdy, heavy-gauge
steel chassis protected by a steel cover finished in gray
textured enamel.

COAXIAL CABLE RECOMMENDATIONS
CAUTION:
A
Careful selection of the proper cab/e is essen-
tial to obtain the bestperformance from this equipment.
Vicon assumes no responsibility for poor performance
when cables other than those recommended are in-
stalled. In all cases, coaxial cable impedance should be
7.5 ohms.
Installation Tips
Do not stretch cable or subject it to sharp bends.
Keep the cable out of contact with hot pipes or any other heat
source. Even ifthere is notenough heattocauseobviousdamage
to the cable, transmission characteristics will be affected.
Materials
Use only cable with a pure copper center conductor, Do not
use cable with either a copper-plated steel or an aluminum
center conductor because these do not transfer signals effec-
tively in the frequency range used in CCTV networks. Acenter
conductor with low DC resistance is required for effective
CCTV operation.
Solid-core bare copper conductor is best suited to video
applications, except where flexing occurs. If the coaxial
cable will be subjected to flexing during normal use, select
a cable with a stranded center conductor.
In locations where the cable must be continuously flexed (for
example, with scanners or pan-and-tilt drives), use cable
intended for such movement. This cable will have stranded
wire center conductor.
Use only crimp-type BNC connectors.
Cable Types and Operating Distances
The most commonly used cable types are RG-59/U and
RG-II/U. Each is actually a family of cables with widely
varying electrical characteristics, some of which are
not
suitable for CCTV applications.
The preferred dielectric material is cellular (foam) polyethyl-
ene. It has better electrical characteristics than solid polyeth-
ylene, but is morevulnerableto moisture. Therefore, useonly
solid polyethylene dielectric cable with a heavy exterior
insulation in applications subject to moisture.
The maximum camera-to-unit distance for the three most
common cables is listed in Table A. The characteristics of the
cables in this table should be used as a guideline when cables
other then Belden are used. Materials and construction must
follow the guidelines above. Table B gives some equivalent
cable numbers of other manufacturers. Vicon recommends
The shield must be copper braid providing 95% or better
coverage. the following coaxial cable types, unless otherwise specified

2. INSTALLATION
2.1 Unpacking and Inspection
All Vicon equipment is tested and inspected before leaving
the factory. It is the carrier’s responsibility to deliver the
equipment in the same condition as it left the factory.
2.1.1 INSPECTION FOR VISIBLE DAMAGE
2.1.2 INSPECTION FOR CONCEALED
DAMAGE
As soon as possible after delivery, unpack the unit and
inspect it for concealed damage. Do not discard the carton
or packing materials. If the unit is damaged, contact the
Immediately inspect the cartons upon delivery. Make acarrier immediately and request forms for filing a damage
note of any visible damage on all copies of the carrier’s claim. Make arrangements for a representative of the
freight bill. carrier to inspect the damaged equipment.
Make sure the carrier’s agent (the person making the
delivery) signs the note on all copies of the bill. If the agent
does not have claim forms, contact the carrier’s office.
If the equipment must be returned for repair, follow the
Shipping Instructions at the end of this manual.

for nonterminating (looping) use may be used in the
connector of six separate pieces of video equipment
branch, however the last unit in line must be terminated
(monitors or video cassette recorders). See Figure 2. with 75 ohms.
The V210DA-B may also be used in more complex
systems. Figure 3 illustrates a branching video system,
in which video from a single camera can be viewed at
NOTE: Each output of the V21 ODA-B must be ter-
minuted with 75 ohms, either locally or remotely.
2.3 Connecting the Unit to the System
Figure 2 illustrates a typical system connection for a
simple system; Figure 3 illustrates system connections
for a branching system, Refer to these figures as neces-
sary while performing the following procedures.
2.
3.
1. Connect the input video cable to the connector
marked CAMERA on the rear panel of the
V210DA-B. The V210DA-B can accept video input
from equipment other than cameras.
4,
Connect video cables from connectors 1,2,3,4, 5,
and 6 on the rear panel of the unit to the input
connectors on the associated video equipment.
Terminate unused outputs of the V210DA-B with
75 ohms (Vicon V75T terminators may be used).
Connect the line cord to a power source of the
appropriate voltage.
3. OPERATION
Press the front panel POWER switch to energize the unit.
The power indicator lamp lights when the unit is energized.
X671-697

If an operating failure occurs in the system, inspect all
cables and connections. Check the cameras to ensure that
it is functioning properly. Check each successive connec-
tion for the presence of a good video signal. If necessary,
interchange the V210DA-B output connectors to deter-
mine if the amplifier or the branch wiring is faulty.
This solid-state unit is designed for troublefree operation
in normal room environments. Repairs should only be
attempted by qualified personnel in an adequately
equipped facility.
If local troubleshooting is required, the unit may be
opened using the following procedure.
1. Use a Phillips-head screwdriver to remove the two
top and two side screws.
2. Lift the cover off the chassis.
If it is necessary to change the fuse, be sure to replace it
with one of the same value, l/S A, 3 AG slo blo (120 VAC)
and l/8 A 250 V slo blo (230 VAC).
