Default Re: Ttl

Depends on your application, what are you trying to do?

Generally, TTL will have two modes upon an input, 0V and 5V, 5V bieng laser off, and 0V bieng laser on.
if you are just looking at turning on your laser to run it.. Leave the TTL alone and don't worry about it.

Last thing: *cough* search bar *cough*

Default Re: Ttl

You only need TTL (or analog) modulation if you are doing a project that requires rapid on-off cycles (or color blending), such as a laser scanner, projector, etc.

The other trick is to read the User Instructions
or contact the seller...

From your other Thread... I understood that your
Laser was emitting a beam...

Come on now... did you contact the seller...
Does your laser emit a beam...

EDIT
Did you know that double posting one post after the
other within a short period of time is considered bad
Forum etiquette....
You can easily Edit and Add information to your last
post.. Like I just did here...

Default Re: Ttl

^^^ Jerry is right- just edit and add your new thoughts
iirc you must add power ( I think most of them take 5 vdc) to make a laser with both ttl and analog modulation turn on. But with TTL only you need not use he extra set of wires to fire it up.

They have TTL to do quick off and on w/o harm to the laser as just turning the power off and on is not a good thing,

analog allows you to not only do off and on but also any mW you want from the lasers thus giving you hundreds of colors TTL will only give you 7 colors in a RGB projector.


hope this helps

now you owe me $2

just send that to LPF a a donation
