The topic says it all =)

Ok heres my issue:

about a couple of years ago the team i was on went to a little event held in another high school, brought the robot along everything was fine, go to pack up the OI and its corresponding gear and some how the DB9 cable going from the modem to the OI nearly ripped off the DB9 from the OI. Ok manage to rig it so it works temporarily. 2 years later robot is still in use but no OI! why? because the DB9 connector (for the radio) came off the OI. Ok I bring it to a friend at work who knows ALOT about circuitry and how to solder. He replaced the DB9 for me and fixed any damaged circuitry to the board.

My problems are as follow now:

1) The search / TX light no longer comes on / blinks only the Power on and No Data Radio comes on!
2) no power to the modem

What was Done!

Number 1 happened before when the original DB9 Connector was accidentally torn off and assumed by changing it it would work again.

Number 2 after I got the OI back from my friend I hooked the modem up and checked it - No power to the OI I did a couple of things to check this.

1a Tested for continuity between the DB9 connector on the board and the circuits it led to on the back of the board -ALL OK

1b Tested for continuity between the DB9 Cable and the ciruits that it led to on the back of the board - ALL OK

1c Radio Modem was working before all this and after all this and has not been in anyone elses hands but mine since the repair of the OI.

Im gonna guess that maybe the Search / TX light on the OI is burnt out - I doubt it but thats the only thing I can come up with esp. since the fuse works fine.

Any suggestions. on that issue

for the modem I can only assume that maybe one or more of the circuits on the OI may not be making proper contact

Any suggestions. on that issue


Does anyone know where I can get blueprints for this board other then Innov. FIRST / EWave. I doubt theyll give me the papers =(

Are there any TestPoints on the OI to check?

All I know is that I need HELP =)
