K: To loadLDThe negative electrode
Different application configuration
1,For applications that only need one analog quantity to directly control the output current of the drive board，You can now use onlyCTLInterface Control Board，AN2/POTAndCHSWThe interface does not access any signal。
2 Internal and external control control is required for applications，For example, a power box，Both the local signal，An external analog signal input port is also required。The local signal is generally provided by a potentiometer，Or it occurs by the local single chip Microcomputer，The signal of external control is provided by the user of the box。In this case, you can useCTLTheIcConnecting an external analog signal，AN2/POTDirectly connected to a10k（1k-100kWhatever you want）The potentiometer，OrIc2Local analog signal generated by single chip Microcomputer，And then useCHSWTheSWTo switch from internal control to external control。
3 For fast modulation current required（For example, the power switch of fiber laser）The application，You can useCTLTheIcInput current signal，AN2/POTTheIc2Enter the threshold current signal，And then directlyTTLSignal outputCHSWTheSWTo modulate the current。Of course，Analog direct modulation，Also only usedIcInput fast-changing Analog quantities，Is also possible。
Note，Modulation，Are generally not in0AAdjust with working Current，ButThe threshold to the operating current。0AThe words，First of all, it is not good for laser diode.，Because there is no maintained threshold current，Thermal shock will be at greater，The laser diode adverse。Secondly, the debugging performance is also very poor，Not only will it extend the time for the current to rise，Will also produce excess response time，Thereby reducing the modulation speed。
