Installation and Configuration

Communications

Flow Control Flow control signals regulate data flow for proper communication. Use the Selection FLOW switch on the rear panel S1 switch to select flow control or to disable

flow control. With flow control enabled, you can use either software or hardware protocols to control flow rates. Table 2.3 gives the FLOW switch settings with regards to the markings on the subplate rear panel. For a diagram of the rear panel subplate, see Figure 2.2, on page 16.

Once you select the flow control option, you have to select either software flow control or hardware flow control using the CTS/XO switch (SW1-4) on the rear panel of the power supply. Software flow control uses XON/XOFF protocol while with hardware flow control you have the choice of RTS/CTS or DTR/DSR protocol. Table 2.4 shows the flow control conditions in reference to the CTS/XO switch. To change the hardware flow control protocol, refer to Table

2.3in this section. Figure 2.2, “Power Supply Rear Panel with RS-232 Interface Installed” on page 16 shows the location of the SW1 switch on the power supply rear panel.

Software This software protocol uses special characters that synchronize device

Flow Control communications. The device sends the control code XOFF (ASCII value 13 hex) when it is not ready to receive data. The device sends the control code XON (ASCII value 11) when it is ready to resume receiving data.

To choose XON/XOFF protocol, select the XON switch position shown in Table 2.4.

RS232-XT, RS232-HPD specifications

Xantrex Technology has made significant strides in the field of power electronics, particularly with its RS232-HPD and RS232-XT communication interfaces. These devices are designed to enhance the efficiency and reliability of power management systems, providing users with advanced features and robust technologies.

The RS232-HPD (High Power Device) is optimized for high-performance applications, enabling seamless communication between power devices and control systems. One of its key features is its compatibility with a wide range of power inverters and converters, making it suitable for diverse applications including renewable energy systems, industrial automation, and marine power solutions. The RS232-HPD supports higher baud rates, allowing for faster data transmission and improved responsiveness in monitoring and control operations.

On the other hand, the RS232-XT (Extended Temperature) variant takes durability to the next level. It is designed to operate in extreme temperature conditions, which is crucial for applications located in harsh environments. The RS232-XT retains all the fundamental benefits of the RS232-HPD while providing additional resilience against temperature fluctuations. This feature is particularly advantageous for outdoor installations, where temperature extremes can impact performance and reliability.

Both the RS232-HPD and RS232-XT are equipped with extensive diagnostic tools that enable users to monitor system performance in real-time. These tools include error detection algorithms and status monitoring, which help in identifying potential issues before they escalate. The user-friendly interface simplifies the setup process, making it accessible for both experienced users and those new to power system management.

A standout characteristic of these interfaces is their robust communication protocols, designed to ensure secure data transmission. With built-in protection against common electrical anomalies, such as voltage spikes and electromagnetic interference, the Xantrex RS232 series guarantees uninterrupted operation and data integrity.

Integration with existing systems is straightforward, thanks to their standard RS232 connectivity. This compatibility makes them ideal for retrofitting older systems without the need for significant infrastructure changes.

In conclusion, Xantrex Technology's RS232-HPD and RS232-XT interfaces are exemplary solutions for advanced power management, offering high performance, durability, and ease of use. Their innovative features and robust technologies solidify Xantrex's position as a leader in the power electronics market. Whether for residential, commercial, or industrial applications, these devices stand ready to deliver efficient and reliable power management solutions.
