Aha OK without illustration its a little difficult to articulate. What I propose to do is to connect the 4 pins on the EPSON board to the arduino board, so I do not intend to connect the motor. The pulses are sent to those pins and I want to use Arduino to record the number of pulses. Does this make sense?
Well there is an AC adapter which connects to the board. The supplied plug reads:EPSON AC ADAPTERMODEL: A392BSINPUT: 220 - 240V50-60HZ 0.3A 25WOUTPUT:13.5V --- 1.2A
