Hi

Much like other people I'm sure I've been trying to connect my A155 to A154. I followed the manual on the website and double checked it with another thread I found. Powered up the case and although all lights came on I got the dreaded burning smell. I think I caught it in time but how the blue blazes do you wire this thing up? It's pretty much killing the fun not being able to get it up and running. It shouldn't be this hard should it? Anyone got a picture of theirs they can post?


You have blown one or both modules,
connecting isn't that difficult but first it needs to be repaired.


Hi

Yes that's what I figured but having followed the instructions I'm not sure why it blew. That's why I'm asking if anyone has another pic. I'll have it repaired and then need to make sure it's wired correctly so it doesn't happen again.



And it's really simple.

STEP 1
Pull out the plug from ST1 on the 155
(Keep cable cause it can still be used as buscable if you ever loose or destroy one)
But for now, aside with it.
ST1 wil NO LONGER BE USED

STEP 2
Next to the pluge you just remove sits a second, it's twisted and sits on ST2 next to ST1
Pull out the plug and fold aside for a moment.
THIS WILL CONNECT LATER TO CABLE B plug 1 (B1) in step 4

STEP 3
Look at the 154 and notice there are 3 cables
cable one is the buspower, it has the 18pole plug at it's end, at this moment not yet needed.
Cable 2 is called A
Plug this cable onto ST2 this is the connector on that led board that is NOT on the edge
AGAIN: st1 at the edge REMAINS EMPTY
Red stripe goes down, closest to the edge of the board

STEP4
From the 154 comes a longer cable with 2 connectors pressed to it. They call it B
Both connectors are protected agains shorts with a blind connector.
Manual say you should use the connector at the end called B1
Remove the blind connector from B1, leave the pins in.
Okay? Got it?
Now you should have connector B1 in your hand (yes the one at the end)
At step 2 I asked you to fold away the cable you removed from ST2
LOOK CLOSELY AT THE RED STRIPES and plug the cables together,
My cable from the 154 has not a massive colored stripe but is more some kind of red stipled line
Whatever:
RED GOES TO RED

Remark:
Cable B has two connectors
The second one is ment for your second A-155
You may however swap B1 with B2 if that suits your cable management better
These 2 are 100% the same, it can't go wrong here.


Thanks. I really appreciate this. It still doesn't work cos I fried it but it's booked with a repairer so hopefully it'll coe back fine


Easy to fix ourself.
plug it in and feel wich chips get hot
all socketed, easy fix, cheap fix
it's all TTL CMOS and some OPAMPS

doing self will cost you... maybe....10 bucks.
