3.3 MPC (MAT) OPERATION
The procedures for installation checkout require the use of a Maintenance PC, MPC (MAT), LynxMSS
USB Driver, and a USB cable.
The LynxMSS USB driver (Zadig utility) must be installed first, prior to connect to the Lynx NGT-9000.
A compatible MPC (MAT) revision must be used to communicate successfully with Lynx NGT-9000.
Refer to the Software Revisions information in the General information section (para. 1.12) for details.
NOTES
1. The revision of the MPC (MAT) must be compatible with the unit’s software
release. Refer to software revisions in the General information section for
details. The revision of the MPC (MAT) can be found in the Help/About menu
item at the top of the screen.
2. The screen information for MPC (MAT) is very similar between the panel and
remote mount models of the Lynx NGT-9000. Differences in appearance either
are noted or will be shown in the following procedures.
3. Multiple connections to the NGT-9000 are typical when going through the setup
steps. If more than ten (10) MPC-to-NGT-9000 connections are made over a
single MPC session, shutting down and restarting the MPC may be necessary.
In some instances, multiple MPC connections to the NGT-9000 within a single
MPC session (MPC never shut down) can result in connection problems or
Windows related failure messages.
4. For international customers it is necessary that the PC or laptop is set for an
American Windows installation (not only the language setting), in order for the
MPC (MAT) tool to operate correctly.
Persons performing the checkout should monitor the MPC (MAT) status bar. The bottom left corner of
the screen provides information on connection type and communication status.
• The communication status is either "Connected – green indicator" or "Not Connected – red indicator".
• Messages are also shown on the right side of the status bar providing guidance to the user.
• The operational status of the unit is shown on the MPC (MAT) and is located at the top of the panel
(next to the model ID) and on the status bar.
The operational status is either "Flight" or "Maint". When "Flight" status is shown, the unit is in
either "Normal Operation" or in "Ground Test" modes. When "Maint" status is shown, the unit is in
"Maintenance" mode, with or without WiFi. The Restart function of the MPC (MAT) may be used to
restart into Normal Operational mode, Maintenance mode (with or without WiFi), or Ground Test
mode.
• Maintenance mode (Maint) can be entered within the first 2 minutes from power-on irrespective of
Air/Ground state. After 2 minutes, maintenance mode can only be entered if the Air/Ground state is
On-Ground.
• The Air/Ground state is determined through an optional Weight On Wheels (WOW) input and GPS
Groundspeed. The air/ground state is initially determined based on the last known air/ground state
saved in non-volatile memory. When sensor inputs have become available and the state may be
determined based on sensors, the installed configuration is used to guide the air/ground algorithm to
update the current air/ground state.
NOTE
When the unit is restarted in maintenance mode, the cooling fan is enabled
and the ADS-B discrete output is set to ground, which enables the ADS-B
Out Fail Annunciator lamp if installed.
