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

The minimum and maximum values for the frequency parameter are 20 and 20000, respectively.

For filter types that have a center frequency (e.g., parametric), this parameter specifies the center frequency. For filter types that have a cutoff frequency (e.g, highpass, lowpass, etc.), this parameter specifies the cutoff frequency.

This command has the same format and restrictions as the PEQOA command except that only one parameter, the frequency, is specified instead of all the parameters. See the PEQOA command for more information. To set the frequency parameter for an input parametric EQ filter, use the PEQIF command. To set all the parameters for an input parametric EQ filter, use the PEQIA 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 Description

Set frequency of parametric S01PEQOF1,2,1250 EQ on output 1 , band 2 to

1250 Hz.

Query current frequency

S01PEQOFB,1,? setting of parametric EQ on output B , band 1.

Status Message

S01PEQOF1,2,1250

S01PEQOFB,1,f , where f is the current setting of the frequency parameter for the parametric EQ on output B , band 1. If the frequency parameter of this filter is set to the same value given in the example above, then the status message will be

S01PEQOFB,1,1250 .

8.125. PEQOG -- Set Gain Parameter for Specified Parametric EQ Output Stage

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

The minimum and maximum values for the gain parameter are -20 and 20, respectively.

This command has the same format and restrictions as the PEQOA command except that only one parameter, the gain, is specified instead of all the parameters. See the PEQOA command for more information. To set the gain parameter for an input parametric EQ filter, use the PEQIG command. To set all the parameters for an input parametric EQ filter, use the PEQIA command.

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.
