I'm attempting connect my SiTex flux compass as a heading sensor for my
Furuno 1721 MKII.

The compass input is seperate from the NMEA 0183 input from my GPS.. Totally
different connector.. called the "Gyro Connector", however, according to
the manual it also excepts input from any Flux compass sensor with NMEA 0183
output. The exceptable data (talker/sentence) are HDM, HDG and HDT.

The connector on the Furuno radar has four (4) signal connections. DATA-H,
DATA-C and CLK-H, CLK-C.

Flux compass has NMEA 0183 output (talker/sentence HCHDM (heading), HCDOD
(course) and HCXTR (deviation). Data output connector Data Output is SIGNAL
and RETURN.

I thought this would be a simple matter of connecting compass data SIGNAL
to radar DATA-H and compass RETURN to radar DATA-C.

Doesn't work, not getting a compass input to the radar or the radar isn't
recognizing the input when I try to select it on the setup menu..

Should I be using the CLK-H and CLK-C some how..

Or, what am I missing here??
