That’s the info I was waiting to know. Thanks. Unlike David’s, mine seems to be wired correctly.

If you look at the solder pads under the white power connector, you'll see that one is square (the one nearest the GPS). Square = positive.

If you read the Getting Started wiki page:

you would see the passwd is nwcompass

Dave N20A,

I checked-in a fix to the problem that you reported with beacmin.sh.
Fix GPS to APRS position format: Degrees Minutes.m
https://github.com/nwdigitalradio/n7nix/commit/5821f4ff36b3ca976439c9325f484664476e839a

To get the new script:
I you modified the beacmin.sh script in n7nix/debug then you need to remove it.

cd
cd n7nix/debug
rm beacmin.sh

# To get new script
git pull

When you first run beacmin.sh in may take some time to install the bc program, an
arbitrary precision command line calculator. It will run much more
quickly the next times.

When you get a chance please run beacmin.sh and let me know if it meets your
expectations. You should edit the script to set the SSID to what ever
you want. You should also set the beacon_msg string to use a different icon

Thanks,
/Basil

Thank you. I did a search on SSID so I missed the SID and thought it pulled

Dave,
Thanks for trying out my script.
I will fix the errors you are seeing but I need some more info.
Could you please do the following:

# Go to the directory where beacmin.sh lives.

cd
cd n7nix/debug

# Using your favorite text editor change the following two lines near
# the top of the file.

# 1. Get rid the hash symbol in front of DEBUG=1
#DEBUG=1

# 2. Change the SID number to what ever you want to use.
SID=15

Now run the the beacmin.sh script and copy & paste the console output to
me in
an email.

Thanks, Dave.

I also noticed int your example you show beacon -c and mine is showing

your example show 4 digits and then a decimal. Am I missing something?

Re: +12V polarity? #12vsupply

 

Thank you sir, that clears up everything. And copy on the 2A fuse. I have my pigtail sorted now but thanks for the kind offer to send another. I WILL buy one of those nice looking cases when they come online!

Re: +12V polarity? #12vsupply

 

Red Lead Plus is on the right on all DRAWS Boards. They were opposite on some prototypes that were never shipped. Hence the documentation.

Some pigtails arrived reversed so we had to swap them. This has been a problem, so we have a new dedicated supplier that builds to our spec,

If your cable is BW let us know and we will ship a replacement.

There is a reverse protection diode but if you haven’t fused the link (2A recommended) the diode will short out.

Trying to get up and running with my new DRAWS hat. A DRAWS brochure from 9/18, http://nwdigitalradio.com/wp-content/uploads/2018/09/DRAWSBrochure.pdf , labels the 12V plug, looking down onto the board, with + on the left, going into the round solder pad. - on the right, going into the square solder pad. A DRAWS Brochure from 11/18, http://nwdigitalradio.com/wp-content/uploads/2018/09/DRAWSBrochure-1.pdf ,  on the current website, labels the polarity as opposite. On the draws board I received a couple days ago, the red lead on the power pigtail is on the left, going to the round solder pad, black is on the right going to the square solder pad. There is also a caution under one of the #power threads to mind the polarity of the pigtail, https://nw-digital-radio.groups.io/g/udrc/message/2227 . Which solder pad is +? the round on the left or the square on the right? My pigtail with the red lead going to the round solder pad matches the older brochure, assuming red leads are + like on powerpoles.

TIA
David


Re: +12V polarity? #12vsupply

 

Yessir, that worked like a charm. Making a powerpole adapter as we type. I'm honored to learn from you more experienced folks.

It’s a good thing that you caught that. You can take a small sharp pointed tool and press down on the tab that holds the wire into the plug and slide it out. Reverse the leads and push them back into the plug.
 
As you can see from the photo below, I have run into this problem before. Sometimes we have to watch out for what our friends in China send us.

A simple multi-meter will tell you everything you need to know. Set the meter up to show continuity. Mine beeps steady when I touch the two probes together. With a stand-alone board, not connected to anything, place one probe on top of one metal 6 pin mini DIN case. This is ground. Touch the other probe to either of the pins in the white JST power jack. If you hear a steady tone, that pin is ground. NOTE: you may hear a short beep when you touch the 12 Volt pin, but it will not keep sounding. That is normal.

Well, my pigtail black goes to square solder pad. Maybe wait to hear from the engineer before I plug in.

OK - then the red positive should work.  After that be sure to review https://nw-digital-radio.groups.io/g/udrc/wiki/DRAWS%3A-Image-getting-started

Re: +12V polarity? #12vsupply

 

I don't have one of the latest shipment of boards to physically examine, but red should be positive on the leads.  I have alerted the engineer to confirm, but perhaps someone else has already wired theirs' up and can confirm?
