First time use

Installing Configuration Software

Download the version of the Configuration software that matches your controller firmware. It's likely you have a very recent firmware image, so start by downloading the latest Configuration software.

Configuring the Serial Port

Find and run the Configuration software by finding the icon under the Start Menu program group. Once the program is running, you can configure the serial port the MJLJ is connected to by clicking Tools/Configurator Options.

If you don't know which COM port you have the MJLJ connected to, you can discover this under Windows Device Manager: Find the 'My Computer' icon, right-click and select Properties. From this window you will be able to access Device Manager.

Expand the 'Ports (COM & LPT)' to see the list of installed COM ports.

Once you're certain which COM port you're using for the MJLJ, select this value in the Configurator Options.

Connecting to the MJLJ

With the COM port configured, connect the Serial cable to the DB9 connector of the MJLJ and apply power. If you already have the MJLJ wired into your engine's wiring harness, turn the key to 'on'. If you are testing the MJLJ on the bench, you can simply power the unit with a 9V battery or a power supply.
