8.91. LOP -- Set Polarity for Logic Outputs

This command sets the polarity for the 20 logic input pins. Setting the polarity for a given pin to 1 indicates that the polarity should be normal (active high). Setting the polarity for a given pin to 0 indicates that the polarity should be inverted (active low). Active high is considered normal because it would light an LED connected to an output pin if the output pin was in the active state.

This command affects the operation of the LOA and LOD commands. If a logic input pin's polarity is reversed, the operation of these commands is reversed.

By default, the polarity for all pins is set to normal (active high).

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.

8.92. MACROA -- Add Command to Current Macro

This command adds a command to the macro currently in progress. This is used in conjunction with the MACROS and MACROW commands to create a new macro.

The syntax of this command specifies a macro number, a comma, and then the command to be added to the macro. The command to be added to the macro can be any valid command except the following:

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.
