Default A Little NMEA Help, Please!

OK here is the scenario I just purchased a Raymarine DS600X and want to connect it to my GPS (Standard Horizon CP-150) and my radar Furuno 1622. Basically the CP150 has a nice temp chart log and I would like to have the temp and depth of my radar screen as well. Here are the wires available:

Furuno Radar

Green:- I assume this is common ground

In my manual it doesn't give me any wire color names for my furuno NMEA cable. Currently I can get the lat and long on the screen by connecting the Yellow to the brown on the GPS and the greens together. However no depth or temp. My manual says that the white must be connected to the TX-H of the navigator, and black must be connected to the TX-C of the Navigator ( Iassume common ground) My question is what is TX-H? The Radar then says connect the TX-H of the video sounder to the yellow of the radar and the green to the TX-C.

Green; Common Nmea Ground
Blue - NMEA 1 Input (+)
Brown - (Nmea 1 Output (+)
Gray - NMEA 2/RTCM Input (+)
White - NMEA 2 Output (+)
Yellow - AutoPilot Nmea 3 Output (+)

White: NMEA input (+)
Green: NMEA Input (-)
Gray: CGND
Yellow: NMEA Output (+)
Brown: NMEA Output (-)

Any help will be appreciated.

GPS Brown - 1622 White
GPS Green - 1622 Black

Sonar Yellow - 1622 Yellow
Sonar Brown - 1622 Green

Probably should also check/configure the NMEA options to make sure the correct sentences are being output as if they aren't being transmitted then no way will they be received by the intended unit.

The 1622 is able to receive MTW (water temp), DBT (Depth below transducer), DBS (Depth below surface) and DPT (Depth) apart from the general/generic GPS position type sentences so for the radar to receive water temp the sounder must be able to transmit MTW and similar one (or all or any) of the depth sentences.

Cheers, Kerry.
