Appendix A. Cable specifications

Shielded cables must be used with this equipment to maintain compliance with radio frequency energy emission regulations and ensure a suitably high level of immunity to electromagnetic disturbances.

A1. USB cables

The construction and maximum length of USB cables is specified in the USB standard. You should only use cables that conform to this USB standard. These cables will be shielded and no longer than 5 metres in length. USB cables have different types of connectors at each end to avoid incorrect connection.

USB peripherals that carry integral cables, such as some keyboards and mice may be connected directly to the AdderView or may be connected to the AdderView via a USB hub (see figure 4). USB hubs may be used to extend the overall USB cable run beyond the 5 metre limit.

A2. Video cables

You will require a video cable for each computer that you wish to connect. The AdderView uses standard video cables that are terminated at each end with a standard 15-way high density D-type male video connector. All the pins on the cable are connected straight through.

We strongly recommend that you use tri-coax 75 ohm video cables that are specifically designed to carry video signals. Good quality 10 metre long tri-coax video cables show little loss of video quality. Lengths up to 30 metres long will usually give an acceptable video picture although the quality falls off as the length increases. You should therefore generally use the minimum length possible.

Tri-coax video cables can easily be identified as they are roughly the same thickness as a monitor’s video cable and are usually lightly fluted on the outside. Cheaper and thinner ‘data’ cables are widely available but are only suitable for low video resolutions. Where possible these cheaper cables should be avoided.
