Startup procedure

Testing the demonstration board requires a PC with a parallel port (ECP printer port), an I²C

bus interface, software (LNBxx control suite), a dual-output power supply (3 A clamp current

or higher) and an electronic load.

–

Step 1: Install the LNBxx control suite software (Software installation)

–

Step 2: Plug the I²C connector on CN3.

–

Step 3: Supply the demo-board through CN1.

–

Step 4: Manage the demo-board through LNBxx control suite software
