All necessary I/O interface connectors applicable for each signal format are provided. Standard interconnects available on the market can be used with the evaluation board. s b O There is also a 2-line backlit LCD with16 characters-per-line, which displays the selection status as well as the control signals sensed by the preprogrammed microcontroller. This evaluation board can be powered by the 9 V adapter provided or by a standard 9 V power supply with a current capacity of at least 500 mA. The source does not need to be regulated.
