PIN 1~8 Output Power Control
PIN1~8 controls the output laser power by TTL signal. The encoding can be set within the
range of 0~255, which is corresponding to the 0~100% output power. The actual output laser
power may not be a linear relationship with these settings. And the actual output power also
related to the frequency. Please refer to the example of current setting in Table 9:
PIN 18-20
