Introduction

Designed to be versatile and adaptable, the Datapath VisionSwitch provides a complete 16x16 video crosspoint switch within a single PCI plug-in card. Larger switch sizes are also possible by adding a second VisionSwitch card to produce either a 32 x 16 or 16 x 32 switch.

VisionSwitch is supplied with driver software for Windows® 2000 and Windows® XP. A simple and intuitive Windows application program is provided enabling users to control the crosspoint switch or, for users who wish to control VisionSwitch from their own software, an SDK is also provided.

VisionSwitch may also be used with the Datapath iH4 and Vantage4 range of multi-screen graphics adapters. In this configuration VisionSwitch is connected to the graphics adapters via inter-card ribbon cables, enabling the iH4/Vantage4 video overlay’s to select 1 of 16 possible video sources. A single VisionSwitch card will support up to four iH4/Vantage4 graphics adapters.

Models

The Datapath VisionSwitch is available in 2 models:

 VisionSwitch-SA. A general purpose. stand alone video switch.  VisionSwitch-H. This is used with the iH4-PRO/DIG.

Specification:

Unpacking

Your packing box should contain the following items:

 The VisionSwitch plug-in card  Multi-way splitter cables.(2 for the VisionSwitch-SA and 1 for the VisionSwitch-H)  VSRC-set ribbon cables ( VisionSwitch-H only)  Installation CD-ROM

Notes:

All plug-in cards are static sensitive and are packed in antistatic materials. Please keep the card in its packaging until you are ready to install.

Observe anti static precautions when installing this product.

We recommend that you do not discard the packing box until you are completely satisfied with the Vision Switch, and it is fully installed and working correctly. We also recommend that you make note of the serial number of the card in a prominent place before you plug the card into the computer. This should hasten any query should you need to contact our Technical Support Department. The serial number is displayed on the card and the box label.

Installing VisionSwitch

Note:

You are likely to need a flat blade and a Phillips head screwdriver for the installation so please ensure you have these to hand before you begin.

Power down your complete system (including peripherals) at the PC and the main power supply. Disconnect all the cables connected to the PC, noting the positions for correct reconnection after

the VisionSwitch is installed. Carefully remove the cover from your PC. Locate an available PCI slot to install your Vision Switch. You may need to remove the expansion

slot cover and screw, please retain these for future use. Holding the card firmly by its top edge at each end of the card’s length, slide it into the slot. Using the retain screw, secure the bracket to the back panel.

Replace the cover on your PC.

Video Inputs/ Outputs

The video signal is connected to the VisionSwitch using a 16-way splitter cable (provided). The cable consists of 16 BNC sockets connected to a 26-way D plug.

The D plug should be connected to the Input socket on the back panel of the VisionSwitch. The Input socket is the top socket. Each BNC socket is labelled to show the video input channel number. i e. 1 – 16.

The Datapath VisionSwitch-SA is a stand alone, general purpose video switch. A second splitter cable is provided to channel the video outputs from the card. The sockets on the back panel of the card are identical; therefore the same type of splitter cable is used for both input and output.

The bottom D-connector located on the back panel is only used if outputs from the VisionSwitch-SA are to be monitored. This would not be required if the VisionSwitch-H is used.

Jumper Links

There are a number of jumper links located on the face of the VisionSwitch card. Links 1 - 36 are user selectable.

The user links provide the following functions: Links 1 to 16

Selects 75ohm termination for the video inputs. LK1, when fitted terminates video input channel 1. The links 2 – 16 provide termination for channels 2 – 16.

Links 17 to 32 Selects 75ohm termination for the video outputs. LK17 when fitted terminates video output channel

1. The links 18 – 32 provide termination for outputs 2 to 16. Links 33 to 36 These links are always fitted when using a single VisionSwitch card. All cards are shipped with all links (1 – 36) fitted.
