Emax

Thanks a lot, it surely brings some light...

But I still don’t know where to solder my blue cable on the daughter board.

I think my daughter board includes some fixes you’re talking about, so only removing pin 1&32 and soldering the wire should not work.

There are 2-3 different pins on the daughter board to which the blue wire could be connected, but which one ?

A picture from a original Emax SE rack could help, or the service manual page 78 and up (only have the first 78 pages).

Since this is the +5V, I don’t want to solder the wire to the wrong pin…

I made a post off the FAQ page with a pic.

Hopefully that is helpful for you…

Eric-

 

you can't send pics directly to the group.

If you post the links somewhere (hosting, instagram, etc), then send us the links we can review the pics....

 

I believe you are talking about a wire for voltage regulation of the E-chip- but again- would have to see the pics to confirm it.

Dear Emax Group,
I have an Emax SE rack with late PC333 Rev A board (see pic 001) with E-chip
Rev B mounted on a daughter board (see pic 002).
A blue wire is (was) connected between this daughter board (pic 003) and the
mother board, from the R19 resistor external side (004).
This wire has been de-soldered from the daughter board but I don't know
where it was soldered (amongst the 4 most left pins nearby...).
I did not find any service manual or picture with this configuration (found
some with wire between E-chip pin 1 and 32, but no R19 resistor).
Can anyone help with a picture or schematics ?
Many thanks,
Eric
