1.2 SYSTEM DESCRIPTION

The MX20 is a multi-function display capable of displaying moving maps, terrain awareness,
obstructions, and VFR/IFR charting functions. An optional datalink provides ADS-B traffic, FIS-B
and TIS-B information. Interfacing to the WX-500 provides lightning strike information on the
display. Interfacing to the WSI Inflight sensor provides Nexrad images, graphic and text METARs,
graphic and text TAFs, EchoTops, Sigmet, Airmet, and Temporary Flight Restriction (TFR)
information.

The MX20 display is also available with an internal GPS. The internal GPS position source permits a
Navigation Uncertainty Category (NUC) value to be calculated and transmitted for ADS-B broadcast.

The MX20 I/O option includes additional interface capabilities that allow connection to the ARINC
453 bus for the display of radar, ARINC 429 support for Goodrich Skywatch interfaces, RS-232
support for Ryan TCAD, Landmark TAWS, and the Honeywell KGP560. The MX20 I/O model is not
available with the optional GPS engine. Interfacing to a Garmin GTX330 Mode S Transponder
provides TIS-A traffic information.

The MX20 must be connected to an external GPS navigation source, such as the UPSAT Apollo GX
or CNX-series, to provide route and flight plan information. The MX20 must be connected to an
external serial altitude source to provide terrain awareness information.

Installation

2 INSTALLATION

This section describes the installation of the MX20 including mounting, wiring, connections, and software
configuration. A post-installation checkout procedure is included at the end of this section.

2.1 PRE-INSTALLATION INFORMATION

Always follow good avionics installation practices per FAA Advisory Circulars (AC) 43.13-1B, 43.13-2A,
and AC 20-138, or later FAA approved revisions of these documents.

Follow the installation procedure in this section as it is presented for a successful installation. Read the
entire section before beginning the procedure. Prior to installation, consider the structural integrity of the
MX20 installation as defined in AC 43.13.2A, Chapter 1. Perform the post installation checkout before
closing the work area in case problems occur.

Complete an electrical load analysis in accordance with AC 43.13-1B, Chapter 11, on the aircraft prior to
starting modification to ensure aircraft has the ability to carry the MX20 load. Refer to Section 2.5.6 for
the power consumption of each MX20 mode of operation (heater on). Document the results of the
electrical load analysis on FAA Form 337.

2.2 INSTALLATION OVERVIEW

A successful installation should start with careful planning including determination of mounting location
for the MX20, cable routing, and other required modifications. Once the mounting location has been
determined, prepare the mounting frames for installation. It may be easier to complete the wiring harness
and attach the connectors to the mounting frame before installing the mounting frame.

Carefully plan which external devices are to be connected to which MX20 ports observing the special
characteristics of ports 3 and 4.

2.3 INSTALLATION CONSIDERATIONS

2.3.1 EXISTING SENSORS

When the MX20 is installed with external sensors, these sensors must be installed with manufacturer's
data. This manual does not provide information for the installation of specific external sensors.

2.3.2 MOUNTING CONSIDERATIONS

The MX20 is designed to mount in the avionics stack in the aircraft instrument panel within view and
reach of the pilot. The MX20 must be located where the operator will have easy access to the controls and
adequate viewing of the display. The preferred location would minimize pilot head movement when
transitioning between looking outside of the flight deck and viewing and operating the MX20. Sample
diagrams of typical cockpit front panel views of the MX20 are shown in Figure 4 and Figure 5.

The standard package includes a mounting frame for ease of mounting, connections, and service of the
unit. Allow an additional one-inch clearance to the rear of the mounting frame for connectors and cables.
Mounting frame details are shown in Figure 6, Figure 7, Figure 8, and Figure 9. Use of mounting tube
P/N 310-0429-01, or later FAA approved revision, is recommended for all installations and is required for
helicopter installations.

The MX20 does not require external cooling. When mounting the MX20, leave a clearance of 1/8 to 1/4
inch between avionics to allow for air circulation.

2.3.3 MINIMUM SYSTEM CONFIGURATION

The MX20 requires connections to the following equipment as a minimum, as appropriate for each unit:

• Power input

• Serial position input device (such as the Apollo GX60, Apollo CNX-series, or equivalent)

• Serial altitude encoder

The serial I/O requirements are located in Appendix A of this manual.

2.3.4 AIR CIRCULATION

No external cooling is required for the MX20. Newer units will have an internal fan installed. Previous
units may be modified to include an internal fan, if desired. No special provisions are required during
installation to accommodate the fan except to ensure the fan opening is not blocked.

2.3.5 COMPASS SAFE DISTANCE

After reconfiguring the avionics in the cockpit panel, if the MX20 is mounted less than seven inches from
the compass, recalibrate the compass and make the necessary changes for noting correction data.

2.3.6 VIEWING ANGLE

The MX20 shall be located such that the operator will have easy access to the controls and have adequate
view of the display. The MX20 may be adequately viewed from the primary pilot’s position when the
following minimums are met:

Up: 20 degrees off pilot’s eye center line

2.4 EQUIPMENT MOUNTING

Once the cable assemblies have been made, attach each connector to the rear connector mounting plate
and the mounting tube as illustrated in Figure 10. Route the wiring bundle as appropriate.

Use tie wraps to secure the cable to the rear connector plate to provide strain relief for the cable assembly
as shown in View A of Figure 10. Connect the shield grounds directly to the grounding lug.

Mounting Tube

Secure the mounting tube to the instrument panel structure using the sixteen screws. The AN507 6-32
screws have a 100
countersunk to accept the screw head so that the screw head is flush with the inside surface of the
mounting tube.

Failure to properly countersink the mounting holes will result in damage to the MX20.
Mounting screw heads must not protrude into the mounting tube.

The mounting tube should be flush to the instrument panel and allow sufficient clearance for the back of the
bezel of the MX20 to mount flush to the mounting tube. Sufficient clearance must exist in the instrument
panel opening to allow ease of insertion and removal of the MX20.

If the back of the MX20 bezel does not mount flush to the mounting tube, the connector may
not engage fully.

countersink head. The mating holes in the instrument panel structure must also be

CAUTION

CAUTION

An alternate mounting configuration can be accomplished using locally-fabricated L brackets. Make the

brackets from 20-24 T3 aluminum, 0.040", and form a 90

o

bend. When attaching the L brackets to the

mounting tube, screw heads must not protrude into the mounting tube.
Once the cable assemblies are complete and the connectors are attached to the mounting frame, install the
mounting frame assembly in the instrument panel. Be sure to use AN507 flat head screws so the unit will
slide in and out freely. Attach the front of the mounting frame to the instrument panel. Use support
brackets to attach the rear of the frame to the aircraft. Cable wiring to the mounting frame is shown in
Figure 10.

Slide the unit into the frame and hand-tighten the threaded screw shaft using the 3/32" hex driver provided in

the installation package. The unit will be pulled into the frame by the shaft and the connectors will fully
engage. The back of the bezel must only be flush to the mounting tube.
To remove the unit from the mounting frame, unscrew the screw shaft. The unit will be loosened and then
may be pulled from the frame. No special extraction tools are required.

2.5 ELECTRICAL CONNECTIONS

The MX20 installation kit includes connectors and crimp contacts. Make the crimp connections with a
crimp tool as specified in the Special Tools Required section on page 6. Wires should be 20 to 24 AWG
for the 37-pin connector and 22-30 AWG for the 62-pin connector, unless otherwise specified. Power and
ground wires should be 20 AWG. Shield grounds should be as short as possible and connected to the
grounding lug on the back of the chassis with wire of three inches, or less.

• Wiring shall be in accordance with AC 43.13-1B.

• All RS-422 or RS-232 connections should be made with twisted pair shielded cable.

• All ARINC 453/708 connections should be made with 70 ohm, constant impedance, twisted pair

shielded cable.

• All ARINC 429 connections should be made with twisted pair shielded cable.

2.5.1 MX20 BASIC DATA PORT CONFIGURATION

The basic MX20 supports four I/O ports on connector J1. Three of the ports are RS232 and one is RS422.
The usage of each port is assigned during the configuration procedure (see section 2.7). The diagram
below provides an example of a configuration for the data ports. Samples of typical wiring configurations
are shown in section 2.5.7.

The following table shows the suggested port usage, however note that the software must be configured to
match the installed MX20 wiring configuration. Note that only one traffic source may be connected to the
MX20 I/O at one time.

PORT 1 RS232 GX50/60* or equivalent GX50/60* or equivalent
PORT 2 RS232 Altitude Encoder* or option Altitude encoder* or option
PORT 3 RS232 Internal GPS** SL30, or option
PORT 4 RS422 UAT Datalink Radio or option WX-500 or option

* A GX-series unit running software version 3.2 or higher and enabled for extended mode and a CNX-series

unit is capable of receiving altitude data from the altitude encoder and passing the data to the MX20. This
configuration opens up an MX20 port for other options.

** If the MX20 is configured with an internal GPS engine, Port 3 is not available for external connections.
