Yes - thats the one I bought.
I have been using mine with an extension cable (since I
need to plug and unplug much more often than most users),
and the cable comes toward the driver, up and over the steering
column housing (just under the dashboard display), and
then down to the console area.
Do you also use cellotape to stick the wire to the plastic panel ?

Since I suspect that there will be many firmware updates as time progresses, what is the cheapest and easiest programmer one can buy for this? I seem to remember a nice USB unit but there was some question as to whether or not is could program this unit...

I got the right-angle 6' all-pin OBD extension cable and it works great.

It stays connected to the DTC, and I have it zip-tied to the underbelly of the dash, right under the plastic lip.
It curves around the center console and pops out at the passenger's feet. This way I save wear/tear on the car's socket and plug in whatever I need.

And yes, don't short the can bus or the car comes to a fast stop.

Note: These should arrive today, and I have yet to test them.
I intend to have suitable connectors and wires in the SOC-Meter Kit.

---------- (more later) ----------
Did you get them ? How are they - and what length did you get ?

They also have jumper wires which can be attached to individual pins.

Yes, thanks, I got some of the 6-inch ones.
Perhaps to use attaching the push-buttons. to EXT1.

Gary, BTW, how are you powering the AVR ? I was going to use an old Panasonic phone adapter, which is supposed to be 9V, but shows 15V when I checked with a multimeter!

Power for AVR-CAN Board:

1. When powered by OBD (12v nominal but might be 14v), I generally go through a 5v (1 watt) zener diode. That external "power-in" feeds an on-board regulator to produce the well-regulated 5v that the board actually uses.

2. Sometimes a board can be powered by a USB-powered JTAG programmer, where the 5v goes directly to the board's 5v buss. However the AVR-CAN's 5v buss is powered by an on-board regulator, so this method shoud NOT be used to powet the AVR-CAN board.

3. The AVR-CAN could be powered by a 9v battery, but one must be careful to NOT lose power in the middle of flashing, or the micro-processor could become un-responsive (effectively dead). I do not have enough experience with the Atmel AT90CAN123 uP to evaluate the risk, but it usually exists.

4. Finally: I use an inexpensive ($4), all-voltage, AC-to-DC power supply (CA-590) that produces well-regulated 8.4v (600 ma) DC ... that was originally made to power a Canon camera, as I recall. I just found it for this project, and bought a couple. It seems to work well.

NOTE: The "well-regulated" symbol/icon/mark is (I THINK) a small square outline with another small square outline within the first. OR, this icon might just mean double-insulated, I an not sure.

Non-regulated (or poorly-regulated) power supplies generally produce something near the rated output voltage ONLY when loaded down enough to supply approximately the rated current. When lightly loaded (or un-loaded) they can produce a WAY higher voltage, and should generally NOT be used with computer type circuitry.

No - that doesn't work, at least it doesn't when I try !

The document says we need to power using either the special power pins or EXT1/2. Olimex programmer document also tells us to power the AVR separately.

Looks like a quick way to get hold of a 9V power supply for me is to get one of these from RatShack and use a 9V battery. I'll also get a variable voltage power supply.

BTW, I also tried to use an ATX 12 V power (like the one you use for IDE drives). It was a respectable 11.8V - but AVR got hot quickly.
