Connecting a DSM300 to a68 MFD

Is it possible to connect a DSM300 to the a68? If so, which cable do I need? If possible, I am assuming I would use the 10 pin "network" port on the a68, but not sure if the HSB2 or ethernet port on the DSM300 would be used.

My goal is to get a 1kw Airmar TM260 50/2000 kHz transducer (powered to 1kw by DSM300) to display on the a68. If the DSM300 would NOT work, is there another black box sounder that would?

Thanks again for any help, Kyle
