7 Communications Ports on the XDI200
The XDI200 has 3 serial communications ports built into it. You must connect to one of
them to program the XDI200.
7.1.1 PC communications, USB port
The built in USB port allows you to directly connect the XDI200 to your laptop computer
without an adapter. Use the connector built into the wire harness to plug directly into your laptop.
Wh
en plugging the USB jack into your computer, you should hear the “beep-beep” that tells you
that Windows has found the USB equipped XDI200 and that the driver is loading automatically
from Windows. You may have to have your computer connected to the internet to complete this
task. Use Electromotive’s Wintecc4 to begin the calibration process. When opening Wintec4,
make sure that Wintec4 discovers your USB connection and its on the correct port number.
Note on finding the USB port:
If Wintec4 cannot find the USB port it is because the PC has assigned the new USB connection
to a number higher than 12. To correct this, go to your computer control panel and select
hardware device manager. Then look at Ports, If the USB port number shows a number higher
than 12, select that port and then select advanced. Change the port number to one that is less
than 12. Close that and go to Wintec4 control options and change the communications to that
new port number.
7.1.2 PC communications, RS232 Serial port
The XDI200 also has the old style RS232 serial port that some PC computers still have.
The XDI200 functions will work identically for either USB or RS232. Do not use both ports at the
same time. Make sure the Wintec4 software finds the right port number, usually 1 or 2.
7.1.3 CAN bus serial port
XDI200 has a built in CAN bus port to transmit engine data to other computers on your car.
Your supplier of the other computers should have already contacted Electromotive on the details
of the data stream. Remember to turn the CAN bus data on in the calibration set up if you need
it.
