for Automixer

This command sets the local maximum number of open mics (NOM) allowed for the specified automixer. The NOM limit is a local limit, meaning that this limit applies only to the specific Vortex that is is set on. In contrast, the AMGNOM command is a global limit that applies to all linked Vortex

automixers with the same AMBUSID.

The first argument of this command specifies the automixer number (always 1 on the EF2211) to adjust. The second argument specifies the NOM limit (always 1). Even though this is a channel integer command, use of the wildcard for specifying the automixer number is not supported.

This command is not particularly useful on the EF2211 since there is only one mic on this device. However, it is provided in order to be consistent with the command sets of the other Vortex devices.

This command is a channel integer command. See Section 6.3 and Section 6.2 for more information

on this type of command. The minimum and maximum values for this command are 1 and 64, respectively.

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 local NOM for automixer 1 to a

S01AMNOM11 maximum of 1 mics.

Query current local NOM limit for S01AMNOM1? automixer 1.

Status Message

S01AMNOM11

S01AMNOM1x , where x is always 1, since there is only 1 mic on this device.

8.25. AMNOMAT -- Select NOM Attenuation on Each Output

This command enables, disables, or queries NOM attenuation for the specified output (1, A, B, T) . . NOM attenuation is calculated as 10*log(Number of Open Microphones).

Remember that even though there is only one microphone on this device, other microphones can be brought in via the W, X, Y, and Z busses. These signals will have NOM information carried with them from the other devices, which is why NOM attenuation is provided at the outputs.

This command is a channel boolean command. See Section 6.3 and Section 6.1 for more information on this type of 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.

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.
