Dynon Avionics EMS-D120 Installation Guide - Manual (Page 34)

Instrument Installation
PC USB CONNECTION
If you do not have a serial port on your PC, you may use a USB-to-Serial adapter to connect the
EMS-D120 to your PC’s USB port. You may purchase an adapter from us, Radio Shack, or
many computer stores. If you are using Windows 2000 or XP, ensure that the adapter driver CD
is inserted in your PC before plugging the adapter into the USB port for the first time. If you are
using Windows Vista, ensure that you are connected to the Internet and do not use the driver
CD; the operating system will download the correct driver. Also, do not have your EMS-D120
plugged into the USB-to-Serial adapter while installing the driver.
EMS SERIAL HARNESS
On the EMS 37-pin wiring harness available
from Dynon, there are three wires bundled
together, colored orange, yellow, and black, and
terminating in a standard D-sub 9-pin female
connector. If you did not purchase a harness
from Dynon, obtain a 9-pin D-sub connector
and make the three connections shown in the
table.

4-2 EMS-D120 Installation Guide
To verify proper communication between the
EMS-D120 and the PC, use the Dynon Avionics
Product Support Program’s “Detect Firmware Version” function. Download the latest version of
the Support Program from the Dynon Web Site at
downloads.dynonavionics.com .
SL30 and/or GPS connection
Depending on the number and types of Dynon units you own,
you have several options for connecting a GPS unit and/or
Garmin/Apollo SL30 to your Dynon system. The GPS can be
used as a data source for the EFIS, HSI, and Fuel pages, as
well as Dynon’s EFIS-based Autopilot. The SL30 can be
used as a VOR, localizer, or ILS (localizer + glideslope)
source for the HSI. If you wish to connect a GPS and/or
SL30 to your Dynon system, read the section below which
corresponds to your set of Dynon products.
If your system has an HS34, it is required that all
GPS and NAV devices are connected to the HS34.
The EMS-D120 does not support directly connected
GPS and NAV devices when an HS34 is installed in
the system. Refer to the HS34 Installation and
Configuration section in your EFIS-based product’s
Installation Guide for device connection details.
