The I2C version of the Led control card is designed for operation with the TSC (Trigger Sequencer Card) card. The trigger input of led controller expects NIM signal as provided by the external trigger output of the TSC card, the communiction for selecting voltages or a led is done by a I2C bus. For the power supply of the controll card +5.5V is needed to feed the power regulator (LM2940). For the connection between led controller and array a 26 pin flat cable is needed.
