The switcher’s rear panel RS-232 connector (figure 4-1) can be connected to the serial port output of a host device such as a computer or control system. This connection makes software control of the switcher possible. Remote communications with the CrossPoint 42 are via Extron’s Simple Instruction Set (SIS) or using Extron’s Windows-based control program.

The switcher accepts SIS commands through the RS-232 port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each switcher response to an SIS command ends with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.

Switcher-Initiated Messages

When a local event such as a front panel operation occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below (underlined).

Its compatibility with different formats and resolutions makes it a versatile choice for any AV setup.

Another key feature is its advanced signal management technology. The 42 HVA supports EDID (Extended Display Identification Data) management, which ensures that the connected devices are communicating correctly. This helps to prevent issues such as resolution mismatches and allows users to achieve optimal performance from their AV system.

Additionally, the 42 HVA incorporates a feature known as automatic cable equalization. This technology enhances the signal integrity over long cable runs, allowing the device to maintain the quality of the transmitted video even at greater distances. This is particularly important in large venues where cable lengths can be significant.

For ease of use, the Extron 42 HVA includes an intuitive interface that simplifies the setup process. The device can be easily integrated into existing AV systems, and its compact design allows for flexible mounting options. This adaptability makes it an excellent choice for both new installations and upgrades to existing systems.

In summary, the Extron Electronics 42 HVA is a powerful tool in the realm of AV technology. With its HDBaseT support, high-resolution capabilities, and advanced signal management features, it meets the demands of modern audio-visual environments. Its design, functionality, and versatility make it an ideal solution for delivering high-quality video signals over long distances in a range of professional settings.
