Marlec’s battery charge controllers are pre-programmed with regulation settings to match Lead-Acid batteries. The Marlec charge controller universal reprogram software enables you to change the voltage regulation levels and other parameters for the HRDi, Rutland 1200 Controllers (Marine & Terrain) and the Rutland 1803 MPC-2 Controller to suit alternative battery types.

Configure Your Controller in Three Simple Steps:

1. Plug the USB end of the controller interface lead into your PC and allow windows to install all the Drivers.
2.   Insert the USB stick provided into your PC and extract the the application. (The application can also be ran from the USB stick).
3. Connect a DC power supply of the intended system voltage to the Battery terminals of the controller and use the Marlec program installed to change your controller regulation settings.

• The software app and interface cable is only compatible with PC’s running Windows XP or later.
• The controller needs to be powered by a battery or DC power supply of the correct system voltage connected to the main battery terminals on the controller.
