10.1 Introduction
The OnAir 2000M2 supports external CAB (computer-assisted broadcast-
ing) systems. Starting with software version V3.04, also a serial interface
(RS232/RS422) can be used for communication with the CAB system.
Studer DigiMedia System: Information on how to connect and operate the OnAir 2000M2 mixing
console with a DigiMedia CAB system is given in the current DigiMedia
operating instructions.
The serial interface protocol is based on the “Schnittstellen-Spezi-
fikationen Regiepult” of DSA (Digitale Steuerungs- und Automations-
technik, Thomas Volgmann) furthermore called [MONPROT], which was
defined by VCS and Siemens.
The implementation in the OnAir 2000M2 is a subset of [MONPROT].
For detailed information on the telegrams implemented in the OnAir
2000M2, please refer to the “Communication Protocol for Broadcast
Automation” document [BCACOM] (available on request).
