Direct Connection
The direct connection provides the means to use the features of the GUI by
connecting a PC directly to the CCU. 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.)
