I'm looking to buy a buffered, powered jtag, like those shoing on WANNNA_BE'S guide. I can't find any. All I find is buffered but you have to provide a power supply which they don't specify what kind (9V, 12V). i know that the power supply is the difference between the qude mode jtag (which I have) and buffered ones.
Any help is appreciated.

I used to use and recommend only buffered jtags, but now, after using a non-buffered jtag, with 180 ohm resistors, that's all I use. Never fails to jtag anything I hook it to.

The jtag's mili sells are really nice and probably just what your looking for....unless your like skinerd and have no problem building your own.

You'd have a good laugh if you saw my temporary jtag....there is no reason to get fancy, I solder mine in every time, takes all of 2 minutes.
I tried the pogo pin and other types, soldering in is more reliable, and hands free.

I almost always solder on as well. My "Chupy's" jtag I built looks like hell too. Soldering on is definately the way to go most of the time. I still have a pogo pin jtag that I use on the older models that have a jtag port though....if the damn thing will hold itself on the pads by itself.

Are Mili's jtags hands free? do I need to solder? how do the pins connect handfree to the pad on the IRD?
Thanks

Mili sells a pogo pin buffered jtag. No soldering required for most models. How to hook up to the jtag port with mili's jtag are in a how to qick linked to on the link bar to the left of your user name.

How about the power supply, do I need one? what kind?

The jtag uses two AA batteries for power. The connector comes with the jtag.

Not all receivers have the hole needed for a pogo pin jtag.
A hole can be cut, but why, it's so easy to solder in a temp, unpowered, jtag.

All ya need is a 7 or so wire cable a printerport connector & 7 or so 100 watt resistors; soider the resis. to the p. port connector via scamatic's inst. than the wires to them & wa la you have a j-tag - just soider the other ends to the receiver via inst. ( you'll find inst almost anywhere).

I have 2 quad mode jtags, and my god. I have no idea why I struggled with those pogo pin contraptions. The first 3100 you slip off of (by a fraction of an inch) in the middle of programming and you spend the next 4 hours struggling with the fix. . . Lets just say you'd stop what you are currently doing and build yourself a solder in jtag. all your problems will go away. You'll be happy because it cost you $3 to build and the firsttime you have to go back into your IRD to fix something it will be there waiting for you, still soldered in and still working flawlessly. A tip: cat 5 works wonders for this

i am still relatively new. So first i bought a buffered pogo pin JTAG, and did my first 013 with that. it wa a bitch, but once i tried the DB25 / 100 ohm res / CAT5 wire, and soldered it in, i thought why the f*ck have i been messing with that irritating device before. I solder in everytime now. And it has upped the odds of a trouble free flash about 100x.

What is with the powered Jtag? what diff does it make? If i use a standard length printer cable it doesn't seem to work that well i use about 1ft of CAT5, anything longer and it doesn't wanna flash. Would the powered version compensate for length and what I suspect is a sub-par LPT port on my MOBO?

I've tried working on a USB flashing device, but getting help with it.... you think i was askining peeps to go back in time and give Mary a punk rock abortion. :(

I use a 12 foot long extension cable from the PC to the non powered jtag, then about 12 inch wires from jtag to receiver, never a problem.
