Single channel VOA module instruction:
Single channel VOA Module (5V) (Fiber Optical power meter 2 channels)
Accuracy 0.1dB
1. Debug mode
When it is debugging,it connects the serial port to the serial port of the optical power meter, and connect the optical fiber in which you need to debug. When the data of the optical power meter is stable and basic value calibration, then supply power to the module (5V). If the light flashing, it means that the optical fiber line is not connected properly. Wait about 10 minutes to debugging,debugging during the LED light flashing,it is still normally on after finished debugging,The optical power meter displays -41dB.
2. Working mode
In usually, connect the serial port to the computer serial port.
Set the attenuation value command (HEX) EE AA 06 xx xx 00
xx xx is the dB value to be set. If the value is 25.6dB, enter 25.6 x 10 to convert it to hexadecimal 01 00
