    • Since the o-rings will make a pretty tight fit with the tubes, it is recommended that a lubricant be used on the o-ring to assure the o-ring gets seated properly.

    • We like to use a common lubricant called "MagicLube" which is available at many hardware stores.

    • To apply the lubrication to the o-ring, squeeze a small amount of lubrication onto your finger and then move the o-ring through your fingers.

    • When using lubrication it is recommended that you wear gloves.

I can not connect to the ROV. I DID manage to do so once. But only one. Using a Macbook Pro, I disabled the wireless, set the ethernet to 192.168.254.2 and set the mask. Plugged the cable in and the browser times out. I tried switching the ethernet cable to a crossed cabled and that gave me nothing either. I plugged the ROV into a gateway and ran a lan scan. The ROV 192.168.254.1 did not show up.

I'm stumped. Especially as it did connect the first time.

Hey David I had a similar issue, I just updated the beagle bone black and it worked again.

Ethan Lane -

Hey!!! Today I did fished assemblig of my new OpenROV 2.8 everything was incredible well explained and detailed. just a minor couple of things that I figured out because at the end they were very logic. This is an incredible guide for a complex device. yet so simple to follow the guide, and at he end everything worked perfect!

Now I will do the first water test in the pool. hope everything goes well!

Thanks to all the OpenRov team. and Congratulations on this magnificent assembling guide.

Best Regards!!!
