Convention Paper

A High Speed Computer Interface for Professional Audio Equipment Control

Authors: Rosenboom, G.; Kok, Ben H.; Wijnker, E.

AES Convention 84 · Paper 2608 · March 1988

Abstract

The introduction of intelligent professional audio equipment and the wish to control multiple devices from a central position, creates the need for remote control of these devices. Existing computer interfaces and protocols are unsuited for pro audio applications or suffer from high complexity and price. This paper describes a newly developed remote control network for professional sound, light and motor/servo equipment. The network has been developed based on a dedicated serial interface processor. Connections consist of twinax cable and 4-pins XLR connectors. it is controlled by a network controller (primary) that can be inserted like an extension card into a personal computer. The maximum number of connected stations (secondaries) is 250. Key features of the network are: Serial multipoint configuration (efficient connections), synchronous transmission (little overhead), error free data transfer (correction by retransmission), high transmission speed (375 kbits/s), and distances up to 1000 m between primary and secondary.
