parameter, the filter type, is specified instead of all the parameters. See the PEQIA command for more information. To set the slope parameter for an output parametric EQ filter, use the PEQOT command. To set all the parameters for an output parametric EQ filter, use the PEQOA command.

This command is saved to non-volatile memory only as part of a preset. The state of this command will be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.

Example

S01PEQIT1,2,1

S01PEQITB,1,?

Description

Set the type of the parametric EQ on input 1 , band 2 to parametric.

Query current type setting of parametric EQ on input B , band 1.

Status Message

S01PEQIT1,2,1

S01PEQITB,1,t , where t is the current setting of the type parameter for the parametric EQ on input B , band 1. If the type parameter of this filter is set to the same value given in the example above, then the status message will be S01PEQITB,1,1 .

8.121. PEQOA -- Set All Parameters for Specified Parametric EQ Output Stage

This command sets or queries all of the parameters for the parametric equalizer (EQ) filters on output channels 1, A, B, and T output channel T. Each channel has five bands of parametric EQ that can be independently controlled.

The output parametric EQ filter parameters can be set individually via the PEQOT, PEQOF, PEQOB, PEQOG, PEQOS, and PEQOE commands. The input parametric EQ filter parameters can be set simultaneously via the PEQIA command or individually with the PEQIT, PEQIF, PEQIB, PEQIG, PEQIS, and PEQIE commands.

When using this command, you must specify all of the following parameters.

The serial connection is often more reliable than wireless options, which can be susceptible to interference.

Another notable characteristic is its versatile compatibility with a range of devices, including cameras, projectors, and interface panels. This allows users to control multiple devices from a single point, streamlining the operation of complex setups. The straightforward nature of RS-232 commands simplifies integration, which is a significant benefit for both installers and end-users.

Polycom RS-232 also supports various baud rates, giving users the flexibility to optimize communication speed based on their requirements. This adaptability ensures that users can achieve the desired performance, whether they are managing basic functions like power and volume control or more complex commands for switching video sources or adjusting settings.

The technology also features error-checking capabilities, which contribute to its reliability in communication. This reduces the likelihood of issues during operations, ensuring that commands are correctly received and executed. Additionally, its structured protocol aids in diagnosing and troubleshooting, making it easier to manage any issues that arise.

With its robust nature and proven reliability, Polycom RS-232 remains a pivotal technology in the realm of audiovisual communications. Its combination of long-range capabilities, compatibility, flexibility, and reliability makes it an essential tool for enhancing the efficiency of modern communication environments. As technology continues to evolve, the importance of dependable interfaces like Polycom RS-232 cannot be overstated, ensuring seamless integration and operation of sophisticated communication systems. Whether used in educational institutions, corporate environments, or event venues, Polycom RS-232 guarantees a streamlined experience in device management and control.
