How to use it

Basically the OBDLink SX uses an USB to serial converter to connect your computer via USB to the ELM327 compatible chip that connects to your Car.

Usage

on Mac OS X

After connecting the USB cable to your MAC you can check whether the device is visible. If you have macports/lsusb installed with the command

lsusb
Bus 004 Device 001: ID 0403:6015 Future Technology Devices International, Ltd Bridge(I2C/SPI/UART/FIFO)

otherwise/in any case

ioreg -p IOUSB -l -w 0

"idProduct" = 24597
...
"USB Product Name" = "OBDLink SX"
...
"USB Vendor Name" = "ScanTool.net LLC"
"idVendor" = 1027

Then check that the cu.usbserial device is available with

ls -l /dev/cu.usb*
crw-rw-rw-  1 root  wheel   17,   1 10 Jun 14:28 /dev/cu.usbserial-113010822821

The name of the device will depend on your environment.

From there http://pbxbook.com/other/mac-tty.html shows how you can test the connnection via a screen/minicom session. If the device at /dev/cu does not show up you might want to fix the situation - it will depend on the version of your Mac OS.

Working around a bug in Mac OSX El Capitan

There is a built in driver:

/System/Library/Extensions/AppleUSBFTDI.kext

which is the original Apple FTDI driver. You might want to reboot to activate it.
