General
Connection 1	RS-232 DB9

The product is an RS-232 adapter cable from the brand BlackBox, type AVS-CBL-RS232, specifically developed for use with modular video matrix switches from the AVS800 and AVS1600 series. It serves as a connecting element between serial interfaces and Phoenix connectors, enabling the integration of peripheral devices such as video extenders, scalers, or other matrix modules. The cable connects an RS-232 DB9 plug to a 3-pole Phoenix plug and is therefore designed for transmitting serial control and status signals. The length is 1.35 meters, which is sufficient to connect devices in a typical rack or enclosure environment without the cabling becoming excessively strained or cluttered.

Applications

The cable is used in professional video distribution systems, particularly in environments where modular matrix switches are used to control and distribute video and audio sources. It is compatible with various input and output cards that feature serial interfaces, such as the input card AVS-4I-HDB or the output card AVS-4O-HDB. These cards support, among other things, CATx extensions, analog audio, and RS-232 communication, making the cable act as a bridge between the modules and external control devices. It is thus a component of systems used in conference rooms, control centers, or broadcast environments.

Functions and Equipment in Detail

The cable features a standardized RS-232 DB9 plug at one end and a 3-pole Phoenix plug at the other end. This configuration allows connection to devices with a serial interface (RS-232) and simultaneously to systems equipped with Phoenix connectors for power supply or signal lines. The use of Phoenix connectors is common in industrial and professional IT environments, as they provide a secure and robust connection. The cable is designed for use in systems with external power supply or power supplied via the matrix switcher, with the cable itself not being powered — it serves exclusively for signal transmission.

Technology Explained Simply

RS-232 is a standard for serial data transmission, frequently used in controlling peripheral devices. The cable enables the transmission of control commands, status messages, or configuration data between a matrix switcher module and an external device. The use of a Phoenix connector instead of a direct cable connection offers flexibility during installation, as the connection can be easily disconnected and wired. The cable length of 1.35 meters is suitable for use in standard rack installations, eliminating the need for additional extensions. The construction is designed for indoor use, with an operating temperature range of 0 °C to 50 °C, which is sufficient for typical office and server room conditions.

Compatibility and Accessories

The cable is specifically designed for use with certain modules of the Modular Video Matrix Switcher. It works in conjunction with the input card AVS-4I-HDB and the output card AVS-4O-HDB, both of which feature serial interfaces. Additionally, it is compatible with other devices such as the Multi-Format Video Scaler AVSC-5DA1-HDB, video extenders like AVS-HDB-WPTX, AVS-HDB-4TX, AVS-HDB-TX, and AVS-HDB-RX. These devices use the RS-232 interface to communicate with the matrix switcher, making the cable an essential part of the system cabling. The combination of these modules enables flexible and scalable video distribution with support for various signal formats, including HDMI, DVI, VGA, and CATx.

Installation and Mounting

Installation is performed by directly connecting the RS-232 DB9 plug to the corresponding device, for example, to a matrix input or output card, and the Phoenix plug to the corresponding connection on the module or an external device. Cabling is typically done within a rack or enclosure, with cable routing designed to avoid mechanical stress. The use of Phoenix connectors allows for quick and secure installation without additional tools. The cable connection is not intended for outdoor use, as no special protection against moisture or mechanical stress is provided.

Advantages in Operation

The cable provides a reliable and standardized connection for serial control signals in video distribution systems. The use of Phoenix connectors increases flexibility during installation and maintenance, as connections can be easily disconnected and rewired. The cable length of 1.35 meters is sufficient for typical rack installations, avoiding the need for additional extensions or cable bridges. Compatibility with a wide range of modules and extender devices enables flexible system expansion and adaptation to different requirements. The operating temperature range of 0 to 50 °C covers most indoor conditions, allowing the cable to be safely used in office and server environments.
