Pasted the scheme here: http://picpaste.com/pics/Screenshot-M9n1LIG0.1327503833.png R1 is 100 ohm, R2 is 220 ohm. R3 is 10K ohm. No diode next to R1. I tested by connecting/disconnecting 4N25 pin1 to GND and measured the voltage on laser power pins. Conclusion - not working. I have 0V on output in both cases. Any ideas, what might be wrong? Can I short-wire +5V to pin4 of 4N25 to test, if it works then? That way I intend to check, if 4N25 is good or no.
