Re: timer after restart

The reset button on the RC must be used. The "RC reset" button on the OI will not work.

The results of power-on resets have been mixed. I have attempted to train our field team to always do a 4-5 second reset after they turn on the power.

We've actually found a way in software to force a reset in under 2 seconds if the camera stops sending data, its also part of our initialization, so even if we have a bad power-up, the camera does come online, it simply takes a bit longer. I don't have specific code for you, I'll email Mark McLeod and ask him to post it when he has a chance, but it essentially clears out the involved variables and sends a few databursts to "wake" the camera, then re-runs the initialization packet sequence, it works pretty reliably for us.
