This command executes the preset corresponding to the specified number, which must be between 0 and 47. The preset must either be a pre-defined factory preset (0 - 15) or a user preset (16 - 47) that has been previously defined via the PRESETW command. If the specified preset is empty, then an

error condition of ERROR#070 will be returned. If one or more of the commands in the preset generated errors, then an error condition of ERROR#072 will be returned.

When the PRESETQ command executes, status messages for all of the commands in the preset will not be generated. The PRESETQ command is provided so that a control system can execute a preset and not generated heavy data traffic from the resulting status messages. Of course, this assumes that the control system is not interested in any of the acknowledgements. The PRESETX command can be

used to execute the preset without suppressing the status messages.

Example Description

Execute preset number 18 without generating any status S01PRESETQ18 messages.

Status Message

S01PRESETQ18

8.135. PRESETW -- Save a Preset

This command writes the current settings of the device into the user preset with the specified number. Since the factory presets (0 - 15) are read-only, an ERROR#071 will be generated if they are specified in the PRESETW command.

Once a preset it saved, it can be recalled via the PRESETX and PRESETQ commands. The preset can also be set to be executed automatically at power-up via the PRESETP command.

This command is saved to global non-volatile memory and is not part of a preset. Its value is saved each time it is changed. It will retain its value after power-down. Since this command writes to non- volatile memory, there will be a delay before an acknowledgment is returned.

Example

Description

Status Message

S01PRESETW18

Save the current device settings as preset 18.

S01PRESETW18

8.136. PRESETX -- Execute a Preset

This command executes the preset corresponding to the specified number, which must be between 0 and 47. The preset must either be a pre-defined factory preset (0 - 15) or a user preset (16 - 47) that has been previously defined via the PRESETW command. If the specified preset is empty, then an

error condition of ERROR#070 will be returned. If one or more of the commands in the preset generated errors, then an error condition of ERROR#072 will be returned.

When the PRESETX command executes, status messages for all of the commands in the preset will be generated (unless acknowledgement mode is turned off). The status messages can be suppressed by using the PRESETQ command, which is exactly the same as the PRESETX command except that status messages are suppressed.

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.
