8.83. LIN -- Assign Command to Logic Input Group

This command assigns a command to be executed when a group of logic input pins is in a certain configuration. Logic groups are defined via the LIG command.

As an example, assume that the command S01LIG2,000001111100000000000000 has been sent to the device. This command configures logic input pins 6-10 to be part of logic group 2. Now, we send the command S01LIN2,10,MACROX25 . This command configures logic input group 2 to execute the command MACROX25 when logic inputs 7 and 9 are active ('1') and logic inputs 6, 8, and 10 are inactive ('0'). The first number in the LIN command specifies which logic group to be affected. The second number specifies the configuraion. In this case, the number '10' translates to '01010' in binary. There are zeros in the positions for the first, third, and last bits -- these correspond to logic inputs 6, 8, and 10 for our case. Similarly, the ones in the second and fourth positions correspond to bits 7 and 9. The last part of the command specifies the command to be executed with the pins enter this configuration.

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

S01LIN2,10,MACROX25

Description

Configure logic input group 2 to execute MACROX25 when the pins in logic input group 2 correspond to the decimal value 10.

Status Message

S01LIN2,10,MACROX25

Query the command associated with decimal

S01LIN1,7,? configuration 7 on logic input group 1.

S01LIN1,7,<string> , where <string>

corresponds to the command that is associated with decimal configuration 7 on logic input group 1.

8.84. LIP -- Set Polarity for Logic Inputs

This command sets the polarity for the 24 logic input pins. Setting the polarity for a given pin to 0 indicates that the polarity should be normal (active low). Setting the polarity for a given pin to 1 indicates that the polarity should be inverted (active high). Active low is considered normal because a

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.
