ME007YS use as trigger

Dear all,

I'm using ME007YS model, and I'd like to use the sensor with trigger.

Now I'm use the sensor is connected with PC through “Waveshere USB to 4ch TTL”.

How can I use the sensor with trigger?

And I saw there are two version about ME007Y (Serial and PWM).

(I think i have serial version)

Anyway, serial version can use trigger system?

Thanks.
