SCX20

[sheakx]

Thanks Bill. Did you put any sealant where the gasket fits into the base? I was thinking that any small amount of water might come in there vs at the top of the gasket. Thanks again.

Yes, a thin film on the base, press the "attachment gasket" in place and then a heavier bead on top of it. Same thing for the larger "roof mount gasket". After connecting the cable I put a thin bead on the underside of the mount, slipped the gasket up and into place. There is some room around the cable so it's not held too snugly in place and kept trying to slide back down the cable while I was applying adhesive to the bottom of the gasket so I switched gears and applied a bead around the 25mm hole in the hardtop instead. Then, holding the gasket in place I flipped and lowered the whole assembly down. It's not scientific but I heard the adhesive popping and squeezing out so I'm sure there's a good seal (I do tend to use more caulk occasionally! )

I'll post up some pics tomorrow of the final parts.

Bill,

Just as a test, I assembled the gasket to the base so it fit nicely all around and then put a 1/4" wide piece of paper through the hole in the bottom of the base and bent over the top of the gasket. When I gently hold the SCX20 to the base, the paper will not pull out, but as soon as I stop holding them together, the paper slides out easily. Seems like mine might be a tighter fit than yours was as I cannot detect a gap when held together.

That sounds perfect and as I would expect the design intent. I didn't measure the gasket or base thickness before assembly but I know on ours there was a slight gap. If that's been corrected (and I suspect it has), life is good!

While I’m waiting for the TZT3 to ship I would like to setup the scx20 thru a Navpilot 300. Is there an updated installation manual for the Navpilot 300 with instructions how? Saw this in the scx20 manual.

When the Navpilot 300 is powered on it will see the SCX20 on the NMEA 2000 bus and offer the Menu to setup and configure the SCX20. If it isn't already covered in the Navpilot 300 manual it will be getting updated to reflect the setup. The software in the Navpilot 300 is already setup to understand the SCX20.

The accuracy of the SCX20 is higher and more stable than the PG700. Therefore, if both compasses are integrated and available on the NMEA2000 network, the SCX20 should be selected as the primary heading source and the PG700 as the secondary heading source. Within any Navpilot or Navnet TZtouch MFD architecture, if a problem were to occur with the primary heading source, the secondary switches in automatically following a visual/audible alarm.

Finished install. Couldn't mount to hardtop without a tall mast to get out of the radar beam which would be less stable and not look right. Yes, I want form and function. Spent some time blue tape mounting and testing and this location looked the best and had performance equal or better than any other positions. Very happy with the results. Great new product!

 

[Johnny Electron]

Great location, it looks great there. Well done.

Johnny just to be sure I understand the roof mount gasket (p/n 20-040-1108-1) goes between the boats mounting surface and roof mounting texture (p/n 20-040-1107-2). And the attachment gasket (p/n 20-040-1106-0) goes between the roof mount texture and the antenna?
The terminology and part numbers are from the installation materials sheet that came with the unit.

Thank you

Thank you for confirming!

I have the SCX 20, interfaced with my Furuno TZT display’s (TZT14 / TZT2), how can I have my nmea 0183 Simrad AP read the heading from scx20?

 

[Quitsa]

The easiest way would be to use the NMEA 0183 output from the TZT 2. You just need to connect it via the NMEA wires in the multicable and turn on the heading sentence in the NMEA 0183 port setup menu on the TZT 2.

I am assuming you have already connected the SCX-20 to a NMEA 2000 network with the TZT2.
