What kind of powertap do I have?

[sonicw]

I bought a P2owertap recently and the seller sold it as a Powertap SL 2.4 (thus implying it can be upgraded to ANT+ spec). I have a feeling it in fact is a wired Powertap SL model. Can you tell this from the photos?







Thanks!

The rear of the CPU has the following numbers:
IC: 6459A-SL2P401.
FCC ID: T8P-SL2P401

This seems to mean that the head unit at least is 2.4 wireless compatible. But what about the hub?

It looks like a wireless model but not a Ant+ version. You can use them with the wireless Joule head but not with Ant+ compatible head units.

I believe Ant+ units are called SL+.

there's an updater to make the hub compatable with ant+ that you can order from saris... i think it's like $50..

Looks like the older 12mm axle generation.

"Comp" was wired with a steel axle and freehub body
"SL" was wired with an aluminum axle and freehub body
"2.4" was wireless but not ANT+
"2.4+" was the 2.4 with the ANT+ firmware update
"SL+" was ANT+ out of the box
"SLC+" was the SL+ with ceramic bearings

Trouble is that the battery covers are interchangeable and may not be original.

A wired hub will not talk to a wireless head unit, even through the wiring harness.
A wireless hub will only talk to a "like" wireless headunit. (ANT<>ANT, ANT+<>ANT+).

Well I did what I should have done earlier and called CycleOps. It turns out the hub is exactly what it appears, a Powertap SL wired. I don't have much use for it now since I need something that connects to my Garmin but I'll see about trading it/returning it. Thanks all.
