IMPORTANT SAFEGUARDS AND WARNINGS
Prior to installation and use of this product, the following WARNINGS should be observed.
1. Installation and servicing should be done only by qualified service personnel and conform to all local codes.
2. Unless the unit is specifically marked as a NEMA Type 3, 3R, 3S, 4, 4X ,6 or 6P enclosure, it is designed for indoor use only and it must not be installed where exposed to rain and moisture.

DESCRIPTION
The VA6200 Series Sequential Switchers manually or automatically switch multiple cameras to a monitor. You can switch up to 20, 12, 8, or 4 cameras to 1 or 2 monitors, depending on the model you have.
The switcher’s second monitor output can be connected to a monitor and/or a Coaxitron® controller. The switchers have an alarm input for each camera and camera ID, and an external trigger to control camera sequencing remotely.

2. Set the jumpers as required for your application. Refer to Figure 1 and Table A.
3. Replace the cover.
4. Place the unit on a flat surface or install it in an equipment rack using the appropriate rack-mount kit.
5. Make all equipment connections to the switcher. Refer to Figure 2. Refer to Table B for the type of coaxial cable to use.
NOTE: The VA6220 switcher is supplied with factory-installed rack ears for mounting in a standard 19-inch rack mount. The rack ears can be removed when using a VA6220 in a desktop application.
Only MON 2 output is Coaxitron compatible.

Cable Type* Maximum Distance
RG59/U 750 ft (229 m)
RG6/U 1,000 ft (305 m)
RG11/U 1,500 ft (457 m)
*Minimum cable requirements:
75 ohms impedance All-copper center conductor All-copper braided shield with 95% braid coverage
6. Wire the alarm inputs, alarm output, and external trigger directly. Refer to Figure 6 to build a cable using either the 15-pin or 25-pin D-type mating connector that is supplied with the switcher.
The alarm inputs require a ground signal to activate them. There is one alarm input for each camera. For example, an alarm on input 5 directs the switcher to select camera 5.
The alarm output is a relay with normally open (N.O.) and normally closed (N.C.) contacts. This connection is intended to activate an external device, such as a VCR, when there is an alarm. Refer to the
Specifications
section for the voltage and
current ratings of the relay.
The external trigger is an input connection. It is for use with time-lapse recorders that have an external trigger output to control the sequencing of cameras.
7. Plug in the power cord. The switcher begins operating.
8. Synchronize the cameras if there is vertical roll when switching between cameras. Refer to the instruction manuals supplied with the cameras.
