Guys,
In wiring up my Ack Avionics E-04, I need to tap into my GPS to provide GPS position to the ELT. Ack only recognizes the standard RS-232 Data, so I can't feed it ARINC429.
In checking my avionics wiring harness I had built up by Stark Avionics...they wired my P1001 GTN650 connector Pin 8 (RS-232 OUT 1) to 4 different outputs (see table below):
1) T22 Xpnder
2) GRT PFD 1 (EFIS display 1)
3) GRT MFD 2 (EFIS display 2)
4) DigiFlight II
On the P1001 connector the other RS-232 OUT pins are currently NOT IN USE.
1) Pin 5 = RS-232 OUT 4
2) Pin 6 = RS-232 OUT 3
3) Pin 7 = RS-232 OUT 2
I read in this thread GTN 650 Aviation out config software Bug? that the GTN650 has a limitation of GTN V2.00 software that only one serial port may provide Aviation Out.
I spoke with Garmin support and he confirmed they'll be coming out with SW v3.00 by then end of Dec/Jan that eliminates this limitation.
As explained to me by the tech at Stark Avionics:
Garmin did not design the GTN series any differently than the GNS series, when it comes to the RS-232 ports. You must continue to use the RS-232 out one for all your ?aviation out? needs. If putting that many lines on one output starts to become a problem, then you will need to buy a RS-232 splitter/amplifier.
So my questions is....
Doe anyone have running either a GTN650, GNS 430 or 530 with a single RS-232 OUT signal feeding 4 devices?
Is it working properly....or do you experience any issues with data integrity?
What is your hardware configuration?
The Garmin Tech explained the rule of thumb is a max of 3 devices being fed by one RS-232 signal. More than that...and the data signal goes from square wave to more sinusoidal....impacting possible the data quality and how its read by the receiving device.
I'd rather fix this now....while the wiring bundle is exposed, then dig it out later.
Thanks,
Howard
