'[PIC] wallwart info pic16 mcd2 (chineese icd2 clon'

I bought a ICD2 on ebay and just received it without wallwart supply.
(several other parts are also missing but for now i can do without them).

I'm eager to start using it but have no clue about what voltage polarity and current it needs.
The little documentation I have and the website are both in chineese without any pictures that would
lead me in the right direction, can anyone help me with this?

Thanks in advance.

Peter van Hoof.

The original package is actually quite good with a nice 40pin ZIF
adapter and a DIP switch to select the PIC types (from 10F to 40pin DIP).
There are some other goodies.

The original power supply is rated as following.
Input: 220V/50Hz Input
Output: 9V/500mA
Polarity: center is negative

The original power supply is bulky and not very good so you do not
really miss it.

Regards,
Xiaofan

My genuine PIC ICD2 has center positive.

Yes. But the OP is talking about MCD2 the ICD2 clone from China.

The basic microchip ICD2 pack doesn't come with one either, assuming the power setup is the same you shouldn't need one unless you plan to power the target from the ICD2.

Microchip ICD2 is 9V/700ma, again it all comes down to if they cloned the power cuircuit or not.

have you tried contacting the seller?

Thank you Xiaofan it took me a while to find a supply with the negative pole in
the center it's a little unusual. It works well.
I have contacted the seller and asked about the missing parts I hope to get them soon.
With a icsp cable I made myself and the supply working I can experiment in the mean time.

Thanks again

Sony have the bad habit of doing negative centre plugs as well.  Now that I
think about it, I can't recall anyone but Sony doing that.

Why don't you look at the clone PC board and see where the traces from
the power input connector connect to the Vreg inputs. Or you could ohm
it out with a DMM. You can tell rather easily which is positive an which
is negative.

Atmel did it on their ICE50.  Didn't have the common courtesy to put it on
a label next to the plug, either.  At least they included robust reverse
polarity protection.

Xiaofan Chen has helped me to the right info already.
It would have been easy to determine what polarity it was if it wasn't for the fact
that the case has stickers on it WARANTY VOID IF REMOVED.
I could not open it (for now).

Sharp have as well. I have told the story here before about the laptop and
overhead projector display both by Sharp, with identical looking supplies.
One had centre positive, and one had centre negative - and the inevitable
happened just before an important presentation to a customer.
