Power supply Voltage

Hello
I just got a pic mutiprogrammer EB006-00-5. It came without an external power supply and I have to get one myself. The problem is that I do not know the voltage that it accepts on the power supply connector ( number 1 in the board layout on page 5 of the document http://www.matrixmultimedia.com/datashe ... 6-30-5.pdf).

Hello Serstel

You can use a voltage anywhere between 12 - 14V. We generally recommend a voltage of about 13.5V but these power supplies can be tricky to find. If you can get a regulated power supply so that you will not fry the board by accidentally shorting wires etc. The board should run happily off around 20mA - 30mA.

I bought a power supply that outputs 12V however its output plug must be congigured by me. It has this signs on it +-o)-- OR +-(o--
Does enyone know which is the polaryty that the board uses?

Hello serstel,

I believe the board accepts both.

Cheers

The Power Supplies have to be connected as +-(o--

Hello,

I also have this type of adapter, although I stupidly threw away the packaging showing what way to place the plug...

But I have found that the board accepts both. I can even remember reading some where that it does support both.

Cheers

Yes - the later versions of the EB006 and HP488 have an onboard bridge rectifier which allows the power supply to be connected either way around. The older versions of these boards required a "positive outer" connection.
