The product and/or manual may bear the following marks:

This symbol indicates that dangerous voltage constituting a risk of electric shock is present within this unit.

This symbol indicates that there are important operating and maintenance instructions in the literature accompanying this unit.

Thoroughly familiarize yourself with the information in this manual prior to installation and operation.

The VSS200DT screen splitter displays video from a single camera or simultaneously displays selected portions of video from two cameras onto one monitor. This feature also allows both cameras to be recorded onto a single video tape recorder (VCR). The VSS200DT screen splitter uses high reliability CMOS technology.

CAUTION:

RISK OF ELECTRIC SHOCK.

DO NOT OPEN.

Front panel controls let you adjust the size and position of a second camera’s picture on the monitor. Either camera can be displayed full screen.

CAMERA REQUIREMENTS

INSTALLATION

VIDEO INPUTS

Each of the two camera inputs is terminated in 75 ohms inside the splitter. So, if you loop a camera video line through a monitor before routing to the splitter, be sure to set the monitor termination switch to HI-Z.

The camera whose video is routed to the camera 1 input will be the master camera. That is, pictures from the camera 2 input will be inserted into the pictures from the camera 1 input.

The master camera can be an economical, random interlace type because the splitter can provide horizontal and vertical synchronization for the second camera. However, a master camera having 2:1 interlace will provide greater synchronization stability. Refer to the

The second camera either must be independently synchronized to the master camera, or it must be a camera that can accept horizontal and vertical synchronization from the splitter (refer to Figure 2). Refer to the

Connectors)

Figure 2 illustrates a typical configuration.

NOTE: (Applies to Figure 2 only.) Camera 2 must be equipped with three BNC connectors (one for VERT drive, one for HORIZ drive, and one for VIDEO), and hooked to the VSS200DT. Camera 1 only needs to be equipped with one BNC connector for the VIDEO.

If you are using a camera with Gen. Lock, the configuration in Figure 3 applies.

NOTE: For installations using cameras with Gen. Lock only, the input termination resistor (R1) must be removed to let the VSS200DT and the camera function properly.

During normal operation CAM 1 is designated as the master camera.

If you want to change CAM 2 to be the master camera, slide the S2 switch on the motherboard in the opposite direction.
