Introduction
The information in this instruction manual covers the installation and maintenance of the V1961VCR-1 and
V1961VCR-2 Vicoax receivers. Throughout this manual, the term V1961VCR refers to all models unless
otherwise stated. This unit should only be installed by a qualified technician using approved materials and
wiring practices in accordance with national, state, and local wiring codes. Read these instructions thoroughly
before beginning an installation.
Vicoax is a digital remote control system designed for use in short-range CCTV applications. Built for
reliability and cost-effectiveness, this system transmits control signals over the video coaxial cable, eliminating
the need for expensive cable runs.
Model V1961VCR Vicoax receiver is designed for use with Vicoax Control Systems. Vicoax systems transmit
video and control information over a single cable. This receiver is an integral part of the complete system.
The system consists of a control transmitter located at the control site and a receiver located at the remote
station. The transmitter sends encoded signals for various control functions over a video coaxial cable to the
receiver. The receiver then decodes the signals into commands that operate the equipment at the remote
station. Transmitters and receivers may both be cascaded in a Vicoax system. Cascading multiple receivers
requires the use of a passive video switcher such as the V1404L.
The V1961VCR may be used with either the V1902VCT or the V1119VCT Vicoax Control Transmitter. The
V1902VCT has a built-in bidirectional amplifier that increases the usable distance between it and the
V1961VCR. Refer to the Reference section, Table A, of this manual for maximum operating distances. The
V1961VCR does not offer preset-position, autoiris, or variable-speed operation, so those functions on the
V1902VCT may not be used. The V1961VCR can accommodate a variety of supply voltage inputs and pan-
and-tilt drive outputs. Models are available for 120 VAC or 230 VAC input with 24 VAC or 120 VAC pan-and-
tilt drive outputs. Refer to the Technical Information section of this manual for specific models. A heater
option, model V1960VCR-H, is available to provide the interior of the housing with thermostatically controlled
temperature. The V1961VCR is housed in an enameled steel case that provides excellent protection from
radio-frequency interference (RFI) and from electromagnetic interference (EMI) in general. The V1961VCR
complies with UL standard 1409, the requirements for an FCC Class A computing device and NEMA
standards for fire safety. Models V1961VCR-1-230 and V1961VCR-2-230 comply with European Community
EMC Directive 89/336. The product was subjected to the testing outlined In the European Normalization
Standard EN 50081-1 (Electromagnetic Compatibility - General Emissions Standard Part 1: Residential,
Commercial and Light Industry), and EN 50082-1 (Electromagnetic Compatibility - Generic Immunity Standard
Part 1: Residential, Commercial, and Light Industry).
Fiber optics provides a very effective method of maximizing the transmission distance of the Vicoax system
while immunizing the signal from electrical disturbances or radio-frequency interference. The V2750-1 fiber-
optic transmission system is designed for use with Vicoax. A complete fiber-optic link requires one V2750T-1
transmitter and one V2750R-1 receiver. These are available in either standalone or rack-mounted model
variations. The V2750T-1 transmitter is located at the camera station, while the V2750R-1 is located with the
transmitter. A single coaxial cable carries both control and video to and from the V2750T-1 and V2750R-1.

Installing and Wiring the Receiver
1. Mount the receiver box to a wall, or other vertical structure, near the camera to be controlled. The
maximum operating distance between the receiver and the camera station is determined by the particular
pan-and-tilt drive and motorized lens. Refer to the instruction manuals for the motorized lens and pan-
and-tilt units to establish this distance.
Caution: The receiver box must be positioned with the cable entry fittings facing downward and protected
from exposure to moisture when mounted outdoors. In addition, all unused cable entries must be
covered and moisture protected to prevent internal damage to the receiver.
Caution: The receiver must be properly grounded to ensure proper operation and protection.
2. Open the receiver by loosening the four captive screws and raise the hinged cover.
3. Route the receiver cables through the appropriate fittings and inside the box to the screw terminal block.
