Hi all,

I have a question for those of you who have installed a Cerulean Sonar MKII ROVL transmitter on the BlueROV.

The installation guide uses a 5V 6A step down/power supply to power the transmitter on the ROV, yet looking at the specifications for MKII transmitter on the website it recommends powering it with >9V. Are we okay to wire the transmitter directly into the power board which supplies most of the other components on the ROV or do we need to purchase a step down?

I have also posted on the cerulean sonar forums but this one looks more active.

Thanks

Hi Perter,

I run mine from the main power distribution. Not through a step down PS.

Cheers!

Thank you, we’ll give that a go!

Hey, we do the same!

The Transmitter is 5 - 28VDC, and we power it straight from the screw terminals feeding from the nominal 14.8VDC 4S main battery.

The Receiver is 4.5 - 16VDC, so a bit more sensitive. I think they did that so you can run it from USB power topside, or from the BROV2 battery.

We run a dual setup, Tx & Rx on the ROV and topside so we get differential heading. Both are powered from the main 4S batt voltage.

Thanks Chandler, we just wired it in yesterday and everything seems to be in order. Next up - field testing!
