3 Step 1 Guide 2 - Software Plug in the ethernet and USB cables to your laptop and watch your ROV power on! The USB connector acts as the on/off switch for the ROV. It takes a minute or two for everything to boot up. The first thing you'll see is lights indicating power in the top control box. Boards will light up in the electronics chassis -- this takes a little longer. The ROV has a built in static IP address of , so to connect with it, your computer's ethernet IP address should be on the same subnet, i.e. " ". The subnet mask should be set to The version of software that shipped with the Pro Camera-HD Upgrade is meant to run off the SD card so should be left in the ROV openrov.dozuki.com Page 3 of 17

When you're done, you will want to change the location back to Automatic so your internet works normally openrov.dozuki.com Page 5 of 17

6 Step 4 Update Google Chrome You need to be running Google Chrome version 53 or later. Click here to learn how to update Chrome. Step 5 Upload Firmware We will now upload the firmware. This is the software that is on the controller board. We will load it from the BBB onto the Controller Board. We have a built in terminal to help with this process, called Wetty : openrov.dozuki.com Page 6 of 17

7 Step 6 openrov login: rov Password: OpenROV When typing your password the characters will not be displayed. Step 7 Once you have logged in your screen will look like this openrov.dozuki.com Page 7 of 17

8 Step 8 Next we will build the firmware. Type the following: sudo node /opt/openrov/system/scripts/buildfir mware.js You will be prompted for the password again: OpenROV Step 9 When it finishes it will look like this openrov.dozuki.com Page 8 of 17

9 Step 10 Now we will load the firmware. Type the following: sudo node /opt/openrov/system/scripts/flashfir mware.js This command is different from the first one. Step 11 When this finishes your screen will look like this. Once this is complete, restart your ROV by unplugging the USB and plugging it back in openrov.dozuki.com Page 9 of 17

10 Step 12 The address for Cockpit is: /cockpit Make sure that when you are typing the IP address you either remove the or are using openrov.dozuki.com Page 10 of 17

11 Step 13 Applets The video in cockpit will be blurry and a little distorted. There is a corrective lens over the camera to correct for the astigmatism caused by the different indices of refraction of light and water through the curved tube. Once your ROV is underwater your video will be clear and not blurry. You will need to add this URL to your favorites in order to make sure your video is not deleted by the browser, read more here. These applets are for different features of the software. Some of the user interface design of these is rough around the edges openrov.dozuki.com Page 11 of 17

12 Step 14 Geomux Settings The geomux controls are for the camera. These settings need to be tuned for your computer system. Framerate: This is the number of frames per second. Bitrate: This is the number of bits that the video stream is. GOP Length: This is the number of frames between iframes (reference frames) Because this stream has to be decoded by your computer the amount of processing power you have dictates what these settings need to be. If you are seeing the video freeze, you should adjust these settings. First drop the bitrate...this starts out at 10 Mb/s and can be lowered to 3 Mb/s without much noticeable quality loss. The GOP length can be shortened to reduce the time the video is frozen (this does take up more bandwidth). The last option would be to lower the framerate openrov.dozuki.com Page 12 of 17

13 Step 15 Recording Video There are three ways to start and stop video recording. Use the "r" button on your keyboard. Use the Switch Panel. Click the "REC" button. Click the stacked disk image at the top of your screen. While recording if you hover over this icon it will tell you how much disk space you have remaining. All video is stored in the Google Chrome cache on your computer. Make sure not to delete your cache before saving all of your data. The storage space is a smaller percent of the total available storage on your harddrive. This is a limitation that Chrome has set openrov.dozuki.com Page 13 of 17

14 Step 16 How to Save Video You can access your recorded video and telemetry using the "data" applet. From here you can export your video and telemetry data. Due to a Chrome limit on the file size that can be downloaded at one time, your video may be broken into many segments. When you first get to the data page your video segment might not initially show up. This is because it is still being processed by your computer, a refresh of the page after a few minutes should bring it up. Some media players have issues playing the video files. We recommend using VLC (a free program) to view your video openrov.dozuki.com Page 14 of 17

15 Step 17 Software Patch We have released a software patch to improve the camera performance. Please apply the patch by following these instructions openrov.dozuki.com Page 15 of 17

16 Step 18 Feedback This version of the software is still a developmental image and is rough around the edges. We would appreciate your feedback on the software and if there are issues that you are having with any of the functionality. Please send us an at: support@openrov.com with the subject line " DEV Image Feedback." If you are having issues with the video stuttering while operating the ROV, these will not show up in the recorded video. The recording is prioritized higher so that it is a smooth playback even if it was not during operation. Based on the feedback we receive and changes we make, we should be releasing the final version of this software version in 1-2 months.
