cancel 10 dB of noise. Higher numbers mean more cancellation will be applied, but may result in slight artifacts depending on the characteristics of the noise. Typical settings are 10 dB for normal cancellation and 6 dB for light cancellation.

When the wildcard character, '*', is used to specify the channel in this command, it only affects input channel 1. To set or query the telephone input channel, T, you must specify it explicitly (e.g., '' ''

'S01NCLT6', '' '' 'S01NCLT?').

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 0 and 20, 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 NC attenuation level on input channel 1 to S01NCL13 3 dB.

Query the NC attenuation level on input S01NCL1? channel 1 .

Set NC attenuation level on all microphone S01NCL*6 input channels (only 1 on EF2211) to 6 dB.

Query NC attenuation level on all microphone S01NCL*? input channels (only 1 on EF2211) .

Status Message

S01NCL13

S01NCL1x , where x is a number between 0 and 20, depending on the current setting of the NC attenuation level on input channel 1 .

S01NCL*è

S01NCL*x, where x is between ä and ÿ, depending on the current setting of the NC attenuation level for input 1.

8.111. NVINIT -- Reinitialize Non-Volatile Memory

This command reinitializes (or formats) all non-volatile memory settings. This will effectively erase settings for global settings, user presets, macros, labels, and logic I/O configurations. This will basically reset the unit to a "fresh-out-of-the-box" state.

When this command is issued, it writes to non-volatile memory in order to format the contents back to the factory default state. The writing process results in a short delay. After the non-volatile memory has been reformatted, the Vortex will perform a software reset, which is equivalent to a power cycle.

Example Description

Reinitialize non-volatile memory and perform a S01NVINIT software reset.

Status Message

No status message will be generated. There will be a short delay and then the Vortex will reset.

RS-232 specifications

Polycom RS-232 is a key interface utilized in various communication and audiovisual systems, enabling effective integration between different devices. This technology employs a standard serial communication protocol that allows for robust control and communication, particularly in environments that require sophisticated audiovisual setups.

One of the main features of Polycom RS-232 is its ability to facilitate point-to-point communication over distances of up to 50 feet without the need for a repeater. This long-range connectivity is essential in large conference rooms and auditoriums where devices are often spread out over considerable distances. 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.
