Ssii Question For You Guys....

Recommended Posts

I have an HP 337 with an SSII in a build that is giving me some grief. It won't turn the camera on. If you turn the camera on manually the board triggers away perfectly but it will not turn the camera on by itself. I thought maybe it was the hack so I redid it twice and the hack is good.

 

I have an older HP337 build with an SSII that I did 3 yrs ago so I pulled it out of the bush and swapped the boards and cameras around. The new camera works with the older board but the older camera will not turn on with the new board.

 

Gary sent me a new chip to try in the board but it didn't help any. Anyone have an idea what may be the problem?? It's got me.....

Loose or cold solder to that pin on the green holder maybe? If you have an Ohm meter check from the pin on the back of the green connector to the front of the green connector where the wire goes in.

Tried it and I get the same reading on all 4 pins so it isn't that. Had me hoping it was something simple like that. LOL!!

Check the solder joints at the opto for the power terminal and also the solder joints on the resistor that goes to the top left leg of the opto (little white chip). I just had the same issue with one of my Safari boards and one side of the resistor for the opto power terminal pin wasn't soldered to the pad causing that opto channel to not work.

Just checked every solder point on it, twice....and don't see anything not soldered Ralph. Could it be a faulty opto? How would I know if it's the culprit?

No it has to be turned off manually too.

There is definitely an issue with that channel on the opto. Just looking at the solder points may not be enough if that is what you did, you need to reflow the solder with a hot iron. Just touch each leg of the opto for just a second and each side of each resistor and then see what happens. If that doesn't get it going then the opto may need changing.

Ok. I'll try that Ralph. Thanks!

Finally got it figured out with lots of help from Gary. The new SSII boards have a new and improved optocoupler on them that for some reason isn't compatible with the HP337 camera. Gary said that was the only thing he could think of on the SSII that had changed so I took an older board out of a P32 build, swapped out the chips and put the older board in the new HP337 build. It works great!! I then stuck the new board in the P32 build and it works great too.

 

Thanks for all the advice and help guys. Gary went out of his way and sent up a new board and a different chip to try as well. Gotta love the homebrew family!! :D

Glad Gary was able to get you going. Seems odd that the new opto won't work with that camera, learn something new all the time.

Yup always something to learn in this game for sure. Had us stumped for a bit but it's all good now.
