The University of the Witwatersrand will be producing over 1200 Low Voltage Power Supplies (LVPS) to power the on-detector electronics of the Tile Calorimeter (TileCal) ATLAS detector in preparation for the Phase II upgrade. Two burn-in type test stations are currently being developed in the high-throughput electronics laboratory. The Load readout board is used to read and control/adjust parameters of four channels electronic dummy load board, and several parameters. In this talk, we discuss how different commands for each PIC micro-controller are written and used to shift bits into the register of the Digital to Analog converter (DAC) contained on the dummy load to control the load current. A hexadecimal source file is thus generated and typically used by programmable logic devices which provides general information of the configured functions.
