PowerFLARM Core

[AS]

Hi all in US-glider land!

I am in the process of installing my brand new core and intend to use the Dsub9 connector for power. Can anyone confirm which color cable is connected to pin 7 (+) and pin 5 (-)?
Why do they keep that such a secret - the manual does not give a hint?
I paid good money for it and don't want to let out the magic smoke the first time I turn it on.

Thanks,

Uli

Just do a continuity check (beeps on my multimeter) on pin 7 and 5 against all the colours. I have had a number of cables (do club installs) with various colours - even from the same distributor, bought at the same time. I do it every time, just to avoid all that smoke coming out. Takes a moment.

On my cable it is:

Yellow = ground
Blue = +12v power

However, I would recommend using a meter to double check your cable before applying any power.

Thanks, guys! Metering 'yellow & blue' it is. The ClearNav link is also very helpful!
Would be nice if FLARM could standardize the wiring harness and publish what is what! Just imagine selling a consumer electronics product and leave the customer guessing ....

The early PF Brick manuals had a chart
matching DB9 wire colors to pins, but
Flarm discovered that suppliers silently
changed them around; so removed the
chart from the manual.

Yep, you have to use a meter to match
colors to pins.

Not sure which manual your looking at but if you download the one here:
http://flarm.com/support/manuals-documents/
It show all the pin outs (pages 11-12) and color chart for DB connector (page 13)

To answer your question white = ground red = 12V power supply. Good luck, just finished my install yesterday.

Karl, I was looking at the manual that came with the unit and it does not show the colors. I metered the pins and you are correct, red is +12V, white is - or ground.
Thanks,

The best way to handle the color-code issue, particularly if you're using
the RS-232 data lines, is to take the supplied cut cable and drop it in a
trash can.

Get a M/F extension cable of appropriate length, and connect it to a
cheap RS-232 to TTL converter with male pins. Note that pins 2, 3, and 5
are conventional usage for 9 pin RS-232, other pins are N/C for the
converter. You'll have a neat little bulkhead connector that can mount
on a junction box, and the RS-232 lines are converted to TTL for you.
Put a little jumper from pin 8 to VCC on the converter to power it, and
whatever other circuitry you want with +5 from FLARM. Then you just have
to send +12 out to the FLARM on pin 7.

Much nicer than trying to solder those flimsy little wires in the cut
cable.
