Function
The add-on module for RS232 and analog audio provides serial data and analog audio transmission to KVM extender systems. The serial interface supports a full-duplex transmission. The signals are transmitted within the KVM data stream via the main extender module. No additional Cat X or fiber link is required.
Application
The module offers one serial interface (RS232) with hardware handshake. DCE devices may be connected to enable direct connection of devices such as touch screens or joysticks. The audio interface allows parallel, bidirectional stereo signal transmission. A line level input allows signal transmission from a sound card or any other line level devices. You can easily connect peripheral devices such as microphones, headsets or speakers.
De-embedding
Commonly used AV and broadcast signals, including SDI, HDMI and DisplayPort include both audio and video signals within a single cable interface. When extended to the analog audio module, the audio signals are maintained within the AV interfaces and additionally extracted and converted to analog audio for output on dedicated audio connectors. The module also allows for the conversion of digital audio signals from CPU add-on modules to analog outputs.
Installation
The module is designed as a half-slot width card to be combined with other add-on modules, e.g. USB 2.0 devices. This provides a significant increase in functionality and flexibility. The Draco vario system allows flexible mounting of modules on all main modules and in all Draco vario chassis.
