When you connect power (8V to 15V) to the VIN2 connection at J4, the jumper at JP3 should be
removed or placed in the EXT position with J5 (VIN1) left unconnected.
When you connect Power to J5 (3V to 5V), change the jumper block on JP3 to connect Pin 2 (VIN1)
to Pin 3 (EXT) and leave J4 (VIN2) unconnected.
When you connect power to J6 (3V to 15V) Change the jumper block on JP1 to connect Pin 2 (VIN3)
to Pin3 (EXT). If you are using a module that has TTL output, not RS232, switch both JP2 and JP4 to
connect Pin 2 and Pin 3 (TTL).
