六、单通道 VOA 模块使用说明:
单通道 VOA 模块(5V) (光纤接光功率计 2 通道)
精度 0.1dB
1、调试模式
调试时将串口接在光功率计串口上,需要调试哪个通道就接好哪个通道光纤,待光功率计读数稳定,校准基准值,再给模块 供电(5V),若灯不停闪烁,则表示光纤线没连接好,断电连接好后,等待大约 10 分钟调试完成,调试期间 LED 灯会闪烁, 调试完成后灯常亮,光功率计显示-41dB。
2、工作模式
正常使用时,将串口接在电脑串口。
设置衰减值命令(HEX) EE AA 06 xx xx 00
xx xx 为要设置的 dB 值。如取值 25.6dB,,则输入 25.6*10,转化为 16 进制为 01 00
