3.3 GDL 69/69A Interface Descriptions
All connections to the GDL 69/69A are provided on the D-sub DB-78 connector labeled P691. The
antenna cable connection is provided on a TNC coaxial connector.
Power
The GDL 69/69A will accept input power from 9 to 33 VDC. The two aircraft power inputs (Aircraft
Power 1, Aircraft Power 2) are intended to allow power to be provided by two different power busses.
Typically, both power input pins are connected on a single bus through a single circuit breaker. If power
is obtained from two different power busses, each leg should have its own circuit breaker.

4 SYSTEM CONFIGURATION AND CHECKOUT
Once the GDL 69/69A and optional GRT 10 have been installed, configure the units for the particular
installation and then complete the checkout procedures herein to verify proper operation. The steps that
are not applicable to a particular installation may be ignored. A checkout log sheet is included at the end
of this section. It is to be filled out during the checkout procedure. The completed checkout log sheet(s)
should be maintained with the aircraft permanent records.
4.1 Post Installation Power Check
Move the aircraft outside and ensure that there is an unobstructed view of the Southern sky. Attach a
ground power cart to the external power connector on the aircraft and apply power.
NOTE
Use of an external power cart is optional in order to prevent the aircraft battery from
discharging to a critically low level.
Power on all systems and allow two to four minutes for initialization. Verify that the control/display unit
and the audio panel are connected and operating properly. Ensure the circuit breaker for the GDL 69/69A
and GRT 10 (if installed) is closed and the Remote Power Discrete (if wired), is enabled.
4.2 Configure RS-232 Port
For installations with the MX20 or GMX 200, refer to the corresponding installation manual for
configuring the correct RS-232 port of the MX20 or GMX 200 that the GDL 69/69A is connected. For
installations with the 400/500 and 400W/500W series units, refer to the 400/500 Series Pilot’s Guide
Addendum or the 400W/500W Series Pilot’s Guides for configuring the correct RS-232 port of the
400/500 or 400W/500W series unit that the GDL 69/69A is connected.
4.3 Configure Ethernet Port
For installations with the GDU 104x, refer to the GDU 104x installation manual, P/N 190-00303-01, for
configuring the GDL 69/69A Ethernet ports.
4.4 Initialization of Configuration Module
The GDL 69/69A requires aircraft installation information to be stored in the configuration module.
For GMX 200, MX20, 400/500 Series units, and 400W/500W Series units the configuration module is
installed in the back panel connector backshell assembly and the only parameter stored in the
configuration module is the variable attenuator value needed to obtain the required GDL 69/69A gain/loss
component.
For installations with the GDU 104x, the configuration information is stored with the G1000 avionics
system, therefore the configuration module is not installed in the GDL 69/69A connector backshell. For
installations with the G1000 avionics system, the configuration information contains the variable
attenuator value and may contain several other parameters.
NOTE
The GDL 69/69A does not provide proper operation until the configuration initialization
procedure is completed.
Configuration Module Procedure for Installation with MX20 and GMX 200
Refer to the latest revision of the MX20 or GMX 200 Installation Manual (Garmin AT Part Number 560-
1025-( ) and 190-00607-04) for instructions.

Rev. F 190-00355-02
Configuration Module Procedure for Installation with 400/500 and
400W/500W Series
Perform the following steps to program the configuration module of the GDL 69/69A when using the
400/500 Series or 400W/500W Series as the control and display unit:
1. Power up the 400/500 or 400W/500W in Configuration Mode (refer to the 400/500 or
400W/500W Install Manual for instructions)
2. Go to GDL CONFIG Page
3. Enter in the Attenuation value, which is computed as in the following formula:
Attenuation = ( 6 – GLcomp )*10
GLcomp = GDL 69/69A gain/loss component value from Table 2-11.
Example: If GLcomp from Table 2-11 is -1.39dB (calculated from example in Section 2.6.4.2)
than;
Attenuation = (6 - (-1.39))*10
= (6+1.39)* 10
Attenuation = 7.39 * 10 = 73.9 rounded up 74 to enter in the 400/500 Series
or 400W/500W Series.
NOTE
If attenuation from the above calculation is < zero or > 100 then the gain/loss
compensation is outside the range required for proper operation. Review Section 2.6.4.2
for appropriate corrective action.

GPS Interference Check
Check that the GRT 10/GRC 10 wireless remote system does not interfere with the existing GPS
installation. This test should be performed for each GPS unit installed in the aircraft. Perform the test
with the GRC 10 in a horizontal and vertical orientation.
1. Power on the GPS installation and view the GPS signal strength of each satellite being received.
NOTE
If the unit is unable to acquire satellites, relocate the aircraft away from obstructions
which might be shading GPS reception.
2. Power on the GDL 69A and GRT 10.
3. Power on the GRC 10 and verify that Channels page and Categories page are populated. NOTE:
It may take up to 10 minutes from the time the GDL 69A is powered on for the GDL 69A to
acquire this information and pass it to the GRC 10.
4. Manually power off the GRC 10.

NOTE
For composite aircraft, hold the GRC 10 as close to the antenna under test as practical
from inside the cabin. For metal aircraft, hold the GRC 10 close to the window nearest
the antenna under test. Repeat the test for the other GPS antenna when complete.
5. While monitoring the signal status of each satellite being received on the GPS, power on the GRC
10 using the XM button and immediately press the button at least once a second for a
minimum of 35 seconds and check the GPS signal reception to make sure it is not affected (no
significant signal degradation). Perform the test with the GRC 10 in the horizontal orientation
with the unit pointing at the antenna. Repeat test with the GRC 10 in the vertical orientation with
the back of the unit pointing at the antenna.
NOTE
If the GDL 69A subscription services with XM Satellite Radio Corporation have not been
activated, only a limited number of channels will be available. In this case, repeated
pressing of the GRC 10 
reached. The GRC 10 is still communicating with the GRT 10 even though the channel
display may not be updated.
4.8 Activation with XM Satellite Radio
Before the GDL 69/69A can be used, the unit has to be activated by XM Satellite Radio and services have
to be subscribed to XM Satellite Radio Corporation. Refer to Garmin Document P/N 190-00355-04.
