TX517EVM: Connect TX517EVM output to Garmin transceiver

Dear Friends,

We're developing a sonar system using these devices:

TX517EVM -> Garmin GT-20 TM Transducer ->  TX810EVM -> AFE5809EVM -> TSW1400EVM

I would like to know how to connect the output of our TX517EVM to the Garmin transceiver. TX517EVM has two outputs, namely, OUTA and OUTB. Also, the wire schematics of the transducer is as follows:

I guess the system should look like the following. However, I don't know how to connect the OUTA of TX517EVM to our transceiver. Should I connect the OUTA  to NEGATIVE and POSITIVE pins of our transceiver?

Any advice is appreciated.

Thanks
