4.1 Optional Accessories The following accessories, which are available from Kramer, can enhance implementation of your switcher. For information regarding them and about cables and additional accessories, contact your Kramer dealer. FC-10D - (Composite-YC Comb Filter/Transcoder) can be serially connected to the switcher for video format conversion (bi-directionally between two popular video formats - composite video and YC (Super-Video).
5. KRAMER VS-5X4 MATRIX This section shows you all of the controls and connections of your switcher. Understanding these helps you realize its full power. The switcher is equipped with RS-232 Connector (for PC Control) and the connector wiring is described later on. The Kramer VS-5x4 is a high performance 5x4 vertical interval matrix switch for composite video and stereo audio signals. It is a true matrix, allowing the user to route any input to any or all outputs simultaneously.

. INSTALLATION 8.1 Rackmounting The VS-5x4 may be rackmounted in a standard 19” (1U) EIA rack assembly and includes rack “ears” at the ends of the front panel. The device does not require any specific spacing above or below the unit for ventilation. To rack mount the matrix, simply place the unit’s rack ears against the rack rails of the rack, and insert standard screws through each of the four corner holes in the rack ears. 9.
If several machines are to be used “in parallel” to switch together, e.g.. when using 4 machines together to make a 5X4 RGBS switcher, then all the parallel machines should be set up to have the same slave number and switch 4 should be ON for the machine which switches the syncs. A 9-pin flat cable should be used to interconnect the machines via their RS-232 ports. The dip-switch settings are as follows: UNIT 1 (Master) UNIT 2 UNIT 3 UNIT 4 UNIT 5 UNIT 6 UNIT 7 UNIT 8 12.
Set your VS 5x4 switcher to Protocol 2000 by setting DIP 5 OFF. Set your VS 5x4 switcher to the old protocol by setting DIP 5 ON. Get full details of Protocol 2000 via the Technical Support section of our Web site (http://www.kramerelectronics.com). Communication with the VIS-5X4 is defined using 2 bytes of information. Data transfer is at 9600 baud, with no parity, 8 data bits and one stop bit.
For example, to connect input 4 to output 2, N12N11N10N9N8 should be set up as 01110 (=14). To connect input 3 to all the outputs, set N12N11N10N9N8 = 11011 (=27). To disconnect output 1, set N12N11N10N9N8 = 11010 (=26). Similarly, if the front panel switches were pressed to connect input 2 to output 3, then N12N11N10N9N8 would be transmitted as 00111 (=7).

15. TAKING CARE OF YOUR MATRIX SWITCHER Do not locate your matrix in an environment where it is susceptible to dust or moisture. Both of these may damage the electronics, and cause erratic operation or failure. Do not locate your switcher where temperature and humidity may be excessive. Doing so may also damage the electronics, and cause erratic operation or failure of your switcher. Do not clean your switcher with abrasives or strong cleaners.
Problem Remedy Noise bars “roll” up or down in the output image Hum bars (ground loop) are caused by a difference in the ground potential of any two or more devices connected to your signal path. This difference is compensated by passing that voltage difference through any available interconnection, including your video cables.
