1. Short-circuit proof single I/O only. Total current should be limited to less than 25 mA.
2. Keep voltages on Digital I/O below Maximum Input Voltage to prevent CEBO-LC from damage. This is
also true, if CEBO-LC is unpowered.
3. Protective circuit of Digital I/O on the screw terminals differs from that on the Sub-D jack.
