Installation and Configuration

Communications

Connections Use a 9-pin (DB9) to 9-pin parallel cable to connect the interface card to the serial port on the host computer. If you need to use a 25-pin connector (DB25) on the host interface, ensure the correct connections are made by referring Table 2.7. If the proper cables are not available and you need to change the transmit/receive pin configuration, see “Transmit / Receive Pin Selection”.

Transmit / The RS-232 interface can use either pin 2 or pin 3 of the RS-232 connector to Receive Pin transmit or receive data. You can set the pin orientation you want by changing the Selection position of the J7 jumper on the interface PCB. Table 2.8, “Jumper Settings for

Transmit/Receive Pin Selection” shows the transmit/receive pin selection on the RS-232 connector in relation to the settings of the J7 jumper. See Figure 2.3, “RS-232 Interface PCB” on page 17 to locate jumper J7.

Removing the In order to access the J7 jumper or the J95 jumper (see page 25) you will need to cover remove the cover. First, turn the unit upside-down and remove the 6 small screws (3 to each side) on the bottom of the power supply. Turn the unit back up the right way. Hold the plastic front panel firmly and lift the metal cover slightly back and

up. The front panel should disengage from the cover. Now, holding the cover straight, slide it towards the back of the unit, along the runners, until it comes fully off.

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.
