Operation

Normally on with power supplied.  Optional TTL/Analogue modulation using blue socket.

If TTL or Analogue control is required, the supplied cable should be plugged into the blue socket on the driver board adjacent to the power supply connection and the required mode selected with the switch.

For TTL action, connect the wires together to blank the laser, the black wire (ground) will pull the red (high) wire low or apply a TTL level (5V) signal. Pulse switching up to 30kHz can be used to reduce the output of the laser.

Analogue action is similar to TTL except the power output is proportional to the voltage, 0V = 0%, 5V = 100% power.
