SRM PC7 - lost power

Are there any SRM PM peeps out there?  The other day I got set to ride on my trainer and I noticed the PC wouldn't show Power (just showed HR, Cad, Spd - but as 0s ofc w/no power).  When I try to pair it again - it doesn't even give me the option to pair the PM (just HR and Spd).  So I'm assuming it doesn't recognize the PM/Magnet combo (the magnet is glued to bottom bracket and is still 3-5 mm from PM). When I plug the PC7 into computer, the SRM software doesn't even recognize the PC7 - its says please turn on the PC7  - which ofc I do.  This makes me think its something w/the PC7 vs. the PM/magnet. 

The PM was installed when I bought the bike.  This is first time since I got bike/PM (last fall) I'm having any recording/pairing issues.  I have an email into SRM - stil waiting on reply.  Any clues? 

Thanks.

And as I right this post - I get email from SRM telling me to send in the PC7 unit for them to look at.....Hate to train w/o it.....

    I always call and talk to shaun...he's walked me thru stuff like this and has always been very helpful. I had similar problem pairing PC7 with new SC sensor. Do you have a Trek sensor ? If so, be sure and pair with Duo S not Duo SC.
    Good luck, these problems are a PIA !

     What OS are you trying to access the PC7?  I have a PC6, and access it through WinXP (currently OSX 10.6 -> Parallels 6 -> WinXP).

    SRM on Windows is a little fussy about what order you install the SRM software + the USB driver.

    The SRM software recognizing the PC6 (or I assume PC7) can/does fail after Windows is put in "sleep" mode.  I frequently "suspend" the WinXP instance in Parallels (different than Windows->Sleep), and can connect my PC6 after multiple suspend/resume via Parallels, and have the PC recognized by Windows/USB and the SRM software.

    Edit: After putting Windows to Sleep and later resuming, in order for Windows to recognize the USB SRM, I have to restart the Windows OS to clear whatever got whacked by putting it to Sleep.

    Also, I find I have to have Parallels, WinXP and the SRM software running before I jack in the PC6 to the USB port.

    Yet another... I had a red PC-to-USB cable that was bad at the PC end.  I could use it, but only with a significant amount of lateral pressure on the connection at the PC... The USB device would donk in and out as I tried to get the correct leverage. I called SRM and they shipped out a new replacement, no questions asked.  Her response was: "there was a bad batch."

     

    Finally, once you get the PC7 connected to the SRM software, go to PC setup, and there will options to set the type of each USB device... I know I had to switch the speed sensor from the Suunto skewer to the SRM(?) frame mounted sensor.  You may have similar options for the PC itself.  I don't have my PC with me at work, so I can't check further.

    @ Joe - the SRM software is loaded on WinXP - I just got a new laptop w/Win7 and hope to move it there once I resolve this. I've had no problems till now with the software recognizing the PC7 - I agree its a little picky about the order when you hook up the PC7 via usb. I think the usb cable is fine though - the computer recognizes that I've attached a new piece of equipment. Last fall I went thru the whole setup process and finally got everything paired and working - so don't know why this suddenly sprung up. I've been going thru home renovations for the last month and I've had to move the bike around alot to get riding - maybe some dust/dirt is affecting the PC7?

    I'm about to go ship it off to SRM now -

    Thanks for all the info.
