Noob, new to the site
« on: September 29, 2019, 09:07:47 PM »
Hello all,  I am sure glad I found this site.  I am building a few ROV's (Shallow and Deep)  I thought it might be interesting to add Sonar scanning to my ROV.  SO I started searching and ended up here.  I thought I would have to purchase an expensive ethernet equipped unit but after looking around the site I see most folks just lengthen the transducer cable using Cat5 or Cat6 cable.

After looking around I figured I could also build a tow fish to help find locations that I want to search with my ROV. 

I do not have a Sonar unit, I am starting to look at the different functions etc.  But I do want to capture NEMA 0183 or 2000 data to get depth GPS etc.

I have just started reading the site and have a few questions. 

When choosing between SI or DI is there a better option?  I see the dual units are a bit more expensive.  Also all ROV's that go beyond 100M  (328 feet)  must use a booster for the ethernet cable,  Not sure but, but I read that most folks run into a length issue.  This booster may help in that department.  Link to Amazon  https://www.amazon.com/dp/B07DGCP853/?coliid=I14HD4YGUYDBG4&colid=2E8DB8T73Y0UW&psc=0&ref_=lv_ov_lig_dp_it

Let me know if anyone has had success using a booster.

Thanks all

Looking forward to chatting and learning what I can

Joe

Hi Joe,
SI gives much more information than DI. The first models with DI used parts of the SI data to show DI (with limited success). When searching for a booster, be aware the transmitted signals are sent through the same wires as the received signals. The voltage may be over 1000 V on transmit. I think it's hard to find a booster that can survive such levels.
