AGW3000C01

3.6.1. Electrical DVB-ASI video connections

All DVB-ASI digital video electrical connections are BNC type. Below are several
recommendations to consider when wiring electrical signals.

BNC connectors used on cables must be suitable for the high frequencies of DVB-ASI
digital video signals: it is strongly recommended to use high quality connectors from
well known manufacturers.

All coaxial cable used must be Belden 8281 or similar. This type provides the greatest
lengths because it is used to calculate the equalizers in the AGW3000C01. Cables
carrying signal between the module and the devices should use single piece
construction, avoiding spliced sections with double BNC female or barrel connectors.
If it is necessary to split the cable into two sections the same type of wire should be
used in both sections.

The use of analog video coaxial cables (RG-59 type or similar) is not recommended for
digital video except for very short distances.
