I have a 200mw Dpss 532nm . Im using the Nu-light DAC & software which is ttl only. Problem is that is does not blank the laser at any time . I have it connected correctly & tried it on positive & negitive blanking (software supports both as does module) . When i probe the signal to the module when blanked i read 0.2 volts but beam is still on. The Lambda Pro nodule i had before blanked correctly with the same setup. Any ideas? I could always add some resistance to the signal to bring it down to a true 0 volts.
