PC Communications

Direct Connection

The direct connection provides the means to use the features of the GUI by connecting a PC directly to the CCU2. This allows field personnel to monitor and control the inverter from a nearby laptop computer directly connected by a serial cable. The computer connects to the inverter directly through one of its serial COM ports running at 9600 baud.

The installed RS232/FO Converter will have to be removed and minor re-wiring will be required.

The RS232/FO Converter kit (Xantrex p/n 1-152624-01) is required for this connection to change the communication protocol from ethernet to serial in the Communications Enclosure. A DB25-to-DB25 gender-changer adapter and DB9/DB25 serial cable are provided with the RS232/FO Converter kit to complete the connection.

If connecting the PC directly to the inverter:

1.Open the Communications Enclosure.

2.Disconnect the TX (transmit-orange) and RX (Receive-blue) wires from the installed RS232/FO Converter in the Communications Enclosure.

3.Disconnect the power plug from the installed converter and plug it into the new RS232/FO Converter.

4.Remove the installed converter. Replace with the new RS232/FO Converter.

5.Reconnect the TX (transmit-orange) and RX (Receive-blue) wires to the new Converter in the Communications Enclosure.

6.Plug the DB25-to-DB25 Gender-changer Adapter into the Serial Communications Port on the RS232/FO Converter. (Step not shown.)

7.Plug the DB25 connector on the serial cable into the gender-adapter and the DB9 connector of the serial cable into the serial port on the computer. (Step not shown.)
