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.

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.

Sync Output (H Drive – V Drive BNC

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.

VIDEO OUTPUT

This output must be terminated with a 75-ohm load. So, if you loop the output through monitors or other accessories, be sure
their terminations are set to HI-Z. Only the last unit on the line should have its termination set to 75 ohms.

SYNC OUTPUT (H DRIVE – V DRIVE BNC CONNECTORS)

When a camera having random interlace is used as the master camera, the second camera must be synchronized by using the
H Drive and V Drive outputs. Refer to Figure 2.

POWER

The supplied five-foot (1.5 m), three-wire line cord with grounded plug complies with safety standards. The unit operates over
a voltage range from 95 to 230 VAC, 50/60 Hz and draws about three watts at 120 VAC.

OPERATION

FRONT PANEL CONTROLS

Figure 4. Front Panel Controls

CAM 1/CAM 2/SPLIT This switch selects camera 1 full screen, camera 2 full screen, or split/insert.
BAL This screwdriver adjustment controls the contrast on camera 2 (the black and white camera).
V SIZE and V POS These screwdriver adjustments control vertical size and position of the split/insert (camera 2 only).
H SIZE and H POS These screwdriver adjustments control horizontal size and position of the split/insert (camera 2 only).
ON/OFF This switch controls power to the unit. The red light indicates the unit is on.

SETUP

1. Turn on the two cameras, the VSS200DT, and the monitor.

2. Set the select switch to CAM 1 (full screen).

3. Adjust camera 1 position and lens until the desired portion of its picture is in the correct position for the composite

display.

4. Set the select switch to CAM 2 (full screen).

5. Adjust camera 2 as in step 3.

6. Set the select switch to SPLIT (split screen).

7. Alternately adjust the insert/split V SIZE/POS (vertical size and position) and H SIZE/POS (horizontal size and position)

screwdriver adjustments until you get the composite picture you want. This moves the camera 2 video only. (You may
have to readjust the position and lens of one or both cameras to get the best composite picture.)

8. Adjust the video contrast of camera 2 (only) using the BAL screwdriver adjustment, if necessary.
