Dynon D100 wiring harness pinout question

[blueflyer]

I have a D100 and a wiring harness I bought through aircraft spruce 3-4 years ago.  I just bought an SL30 and was hooking it to my D100.

The wiring diagram says to connect the pin 22 from the D100 to the serial out pin on the SL30.  The pin 22 on the D100 has a splice in it just after it leaves the DSUB connector.  There is a solid yellow wire (that is bundled with the black and orange wire that leads to the 9 pin DSUB) and a yellow/green wire.

What does that yellow green wire connect?

I connected the Dynon pin 22 (solid yellow bundled wire) and the serial out wire on the SL30.  I then connected the D100 pin 10 (orange bundled wire running to 9pin DSUB) to the serial in pin on the SL30. 

I have the D100 set to SL30 and baud rate of 9600.  I have indicator type on the SL30 set to none. 

I went flying and the SL30 works as it should, but the Dynon HSI is blank....no information is getting to it.

There are hundreds of the D100/SL30 combinations flying without a hitch, so Im sure we can figure this out.

Any suggestions on what I have done wrong?

The Yellow/Green wire is there if you want to connect a GPS. Because all other connections to the serial port have to be removed during a firmware update, instead of splicing into the Yellow and Orange wires, I recommend just installing a mating D9 connector and connecting the device such as the SL30 to the mating connector.

Apologies for the obvious, but you are pushing the NAVSRC button under the CDI and selecting NAV? Until you do that, the CDI "doesn't know" to route the data received from the SL30 to the CDI.

I only have the SL30 hooked up to the D100. I do not see a "NAVSRC" button under CDI.

I believe I have been told in the past that the "NAVSRC" button will only appear if I have 2 different sources of navigation connected to the D100.

Would you agree or disagree with that?

 

[dynonsupport]

You should see a NAVSRC button. Even with one source you get this so you can turn off the CDI if you don't want to use it.

ok, I don't have see a NAVSRC button. Since I don't have a NAVSRC button, I tend to think the D100 is not receiving info from the SL30, so the D100 doesn't think a source of navigation is connected. I have re-verified the wiring is correct.

what should I try next?

Just A thought - what is setup on the SL30 re serial output, set Indicator Head type to NONE

I just removed the yellow wire from pin 22 and replaced it with a new wire that I made. when I turned on the D100 and turned on the SL30, the HSI on the D100 had the VOR info across the top, but the HSI was flagged because I was in the hangar. I think everything is working now. I will fly tomorrow and report back. The NAVSRC button was there now as well.

I have no idea why that yellow wire wasn't working. I tested it for continuity and I did get continuity. I just had no other options, so I replaced the wire and it worked. I don't know why the yellow wire wasn't working.

I flew today. The SL30 and D100 worked as it should. I cant tell you why the yellow wire wasn't working, but it didn't.

 

[blueflyer]

you guys have any thoughts about why the original wire in the harness wasn't working?

What's the point ? - there can be heaps of variables here & without being there & seeing the work it'll be just a lot of conjecture without a definitive result. I rather just spend time building or flying
