Here=99s some information on a new product from Vx Aviation that
greatly simplifies the interconnect of EFIS serial ports plus provides
single-point ground bus distribution: AXIS-15A. I hope list members
find this interesting, as some of the concepts have been discussed on
the forum over the years.
Summary:
=====
Vx Aviation announced the introduction of the AXIS-15A EFIS Wiring Hub.
Providing over 100 pins of connectivity in a compact 3.8=9D x
2.5=9D circuit board, the AXIS-15A device greatly simplifies the
installation of EFIS systems and the connection of associated avionics
in Experimental aircraft.
Using five 15-pin D-Sub connectors, the AXIS-15A device provides for the
distribution of EFIS signals using a backplane structure. Each EFIS is
plugged into one 15-pin connector, then instruments that require
connection to specific signals are connected to one or more of the other
connector pins as appropriate for the application. This method
simplifies installation and maintenance, facilitates future upgrades and
improves system reliability by eliminating the complexity of discrete
wiring and crimp splices.
Additionally, two independent connectors are provided that are wired as
ground or power distribution buses. Each connector has a 7-pin and an
8-pin bus that is easily jumpered into a single 15-pin bus. In total,
this provides up to four independent buses for avionics grounds,
miscellaneous power, dimmer circuits or bias voltages. Heavy current
Fast-On tabs are provided for main ground/power connections....
=====
The website has more information, including an installation guide that
shows the before and after of an typical installation (in this case a
dual Dynon SkyView system). The device is compatible with most EFIS
system, or for that matter any application that requires the
distribution of signals in a structured format. The SkyView is unique
in that multi-EFIS systems have all of their RS-232 receivers and
transmitters connected together. With the AXIS-15A, a second EFIS can
be connected into the system serial ports with one 15-pin wiring harness
and no cutting and splicing of wires.
Thanks,
Vern Little

Guys- I just listed my new, unused SD-8 standby alternator and regulator/OV
kit on eBay, (as well as a couple of old headsets.)
If anyone is doing an AeroElectric system and needs these parts, this will
serve as a heads-up on some good parts deals.
My planned IFR glass panel upgrade has been untouched since 2007, and it's
time to move on and simplify . . .
If the inspiration returns, I'll go shopping again. Till then, these parts
need a good home.
If someone would bump this to the VAF forum, I'd appreciate that as well.

That's a great idea. Lately we've been wiring panels with a dedicated
Amp-type circular connector and running all the serial into one side of the
connector. Then we use the other side as a jumper/adapter to route the
serial where we want it to go.
Trouble is we run out of pins in a 63 pin connector pretty quickly. Garmin
430s, for example, have several channels of 232 and ARINC, as do a lot of
other avionics these days--EFIS, transponder, handheld GPS, etc.
I'll use one of these on our next panel.
