TTL Outputs

[lamborgini8]

Ok, rather confused now. According to the manual for my scanner kit I bought from Chinese department store I should only have one TTL blanking output.

As seen on the rather basic diagram on page 4.

Now if I look at the display DSP I actually have three connectors down the bottom, all two pin connectors and there is actually space for another. Going from left to right they have the letters 'G R', 'G G' and 'G REVS' beneath them. I am confused as to which one is the TTL connector. Or if I am lucky is that three different ones meaning I can have more than one laser connected?

are you talking about the dmx???


also a close up pic would be good

No, I mean the TTL output connectors. The part I connect my laser to for the TTL Blanking effect to work.

Will get images tomorrow

 

[andy_con]

yes, so do you mean connecting the TTL input on the laser module to the dmx or dac???

I think so, yes.

Here, dont have a very good camera so thats all I can do.

The connectors I am talking about are the three at the bottom of the circuit board.

 

[andy_con]

can you highlight on here

the TTL is + and -

so you use the only TTL output on the DMX that works. if im am correct theres only one wrking TTL on the dmx.

put the + to + and - to -

 

[lamborgini8]

That doesn't really help, your circuit is different to mine.

 

[andy_con]

yeah sorry

you need to get me a decent pic

 

[lamborgini8]

yeah sorry

Its the best I can do with my camera.

 

[andy_con]

well theres only two wires so you cant go wrong, + and -

 

[lamborgini8]

well theres only two wires so you cant go wrong, + and -

I guess so... soon find out.

 

[andy_con]

yep, if you connect to a dead ttl it wont do anything

 

[lamborgini8]

Ok, finally have it all wired up and mounted in its new housing now.

Connected up the TTL and wow! Ok so mostly wow... Some of them are perfect like the tunnel effect but when it comes to slightly more complicated animations like a square with arrows pointing out of each side thats rotating... well it doesn't work so well, it seams to be chopping parts off of it. If i switch the cables around the TTL does nothing.

 

[andy_con]

maybe its to large so the scanners miss corners off
