APPENDIX C: AUDIO/SERIAL SUPPORT

Appendix C: Audio/Serial Support

Single head KVM devices:

The Audio/Serial allows bi-directional stereo audio and a full-duplex serial data link to be sent across the regular interconnection cable in addition to keyboard, mouse and DVI video.

Dual head KVM devices and Media devices (no USB):

The Audio/Serial allows bi-directional stereo audio and a 3 wire (Tx/Rx - XON/XOFF) serial data link to be sent across the regular interconnection cable in addition to keyboard, mouse and DVI video.

To set up the extender’s audio and serial link, please follow all of the instructions detailed in this appendix. If you have any questions, contact Technical Support.

Serial Interface - Set Up and Operation

No setting up or user adjustments are required. Please note that the serial link is always active.

Please bear in mind that the Remote Unit’s serial port is wired as DTE (i.e. the same as that on a PC). To connect a serial printer (or other DTE rather than DCE device) to the Remote Unit, you will need a Null-Modem (crossover) cable between the Remote Unit and the printer.

A serial touch screen may be plugged directly into the Remote Unit.

Please note, that media- and Dual head KVM Extender support a 3-wire- connection only (Tx/Rx/GND). Attached devices must support software handshake (XON(XOFF).

Serial Interface - Handling Multiple Serial Devices (Singlehead KVM devices only!)

The extender’s serial interface transmits/receives six signals (3 signals in each direction). Normally four of these signals are used for hardware handshaking (in addition to TX & RX). However, because each handshaking line can support signals up to 19,200 Baud it is possible to configure the serial interface to handle up to three simple 2-wire (Tx/Rx only) serial links. Select XON/XOFF software flow control on the remote device and PC.

To do this you will need to construct a custom breakout cable. Please contact technical support for further information.

The Black Box ACS4022A-R2-xx series is a robust line of KVM extenders designed to meet the demands of modern computing environments. These devices, including models ACS4201A-R2-xx, ACS4222A-R2-xx, ACS2228A-R2-xx, ACS4001A-R2-xx, and ACS2009A-R2-xx, provide seamless connectivity for both single and dual-head systems, enabling users to manage multiple servers and computers from a distance. Each model incorporates high-performance technologies that ensure optimal transmission of video and control signals over extended distances.

One of the standout features of these KVM extenders is their ability to transmit high-definition DVI-D video signals, supporting resolutions up to 1920x1200. This capability is essential for professionals working with graphic-intensive applications, such as video editing, design, and simulation work. The extenders utilize fiber optic cabling, which allows for transmission over long distances—up to 10 kilometers—without signal degradation, making them ideal for setups in large facilities or across multiple rooms.

The ACS series includes both single-head and dual-head options, giving users the flexibility to configure their workstations based on their needs. The dual-head functionality is particularly advantageous for multitasking, allowing users to operate multiple screens simultaneously, thereby enhancing productivity. Additionally, these extenders feature USB connectivity, which facilitates the use of various peripherals, such as keyboards, mice, and audio devices, enhancing the overall user experience.

Reliability and ease of use are core characteristics of the Black Box ACS series. The devices are plug-and-play, meaning they can be easily installed without the need for complicated configurations. This aspect is particularly beneficial for IT managers in fast-paced environments who require efficient solutions with minimal downtime. The ACS series also features robust security protocols to protect sensitive data during transmission, ensuring compliance with industry standards.

In summary, the Black Box ACS4022A-R2-xx series and its counterparts are powerful KVM extenders that provide high-quality video and control signal transmission over great distances. With their support for high resolutions, flexible configurations, ease of use, and security features, they cater to the needs of diverse computing environments, making them an ideal choice for professionals seeking to optimize their workflows.
