8.89. LOK -- Delete One or All Logic Output Pin Commands

This command "kills" or deletes all commands for a given logic output pin. In other words, the commands associated with LOA and LOD will be deleted for the specified logic output. A wildcard

character can also be specified for the logic output pin, in which case the commands for all logic output pins will be deleted.

Using this command is more efficient than deleting one command or pin at a time since this command deletes them all at once and requires fewer writes to non-volatile memory.

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.

ExampleDescription

Delete all the commands associated with logic output pin 5. This one S01LOK5 command is equivalent to executing the commands ' S01LOA5, ' and '

S01LOD5, ' except that this command is more efficient.

Delete all the commands associated with all logic output pins. This one command is equivalent to executing the commands ' S01LOA1, ' and '

S01LOK* S01LOD1, ' for each logic output, except that this command is much more efficient.

8.90. LOM -- Mask Logic Output Pins

This command is used to mask (i.e., disable) logic output pins. The mask consists of 20 fields (one for each logic output) that can each be set to 0 or 1. If the mask bit for a given logic output is set to 1, then the logic output pin works normally. If the mask bit for a given logic output is set to 0, then the logic output is disabled. When a a logic output is disabled, it is "frozen" in whatever state it is in when it is disabled. The output pin's state will not change when the condition that drives it (via LOA and

LOD) changes. However, any changes to that pin caused by setting the values with an LO command

will affect the output pin value. For instance, you could disable (mask) a pin and then explicitly set its value to low with the LO command.

When a logic output pin is re-enabled, it will be updated to the current status of whatever condition drives it (via (LOA and LOD).

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.
