external disengage button (see “Expansions” section). The switch release command is sent by the
software; the software can switch off the A/T ARM switch also for different reason depending by the
status of aircraft systems (fault detected etc.).
If the A/T switch does not stay in the “On” position check aircraft conditions. The A/T ARM switch
also can be manually disengaged.
ON-FLY BACKLIGHT REGULATION
When the MCP is normal running (starts with Project Magenta, PMDG or in test mode using the
CPflight test software) you can on-fly set backlight brightness. To regulate the backlight brightness
hold pushed any pushbutton and rotates in left or right verse the HDG knob. In this case this
regulation keep maintained for the all the flight duration and will be lost when you will turn off the
MCP. To modify and save these parameters permanently please refer to the next section.
(Backlight Brightness menu).
CONFIGURATION MODE
MCP737PRO3 firmware provides an internal program mode to configure some preferences in the
hardware functionality. With the MCP in stand-by (software not running) push and hold the C/O key
for more than 1 second; this start the hardware in configuration mode. This is the only way to
access to the configuration mode; no PC software program is required to configure the
MCP737PRO3 hardware. In program mode only some keys are operating; the Left Course, IAS and
HDG, ALTITUDE, V/S and Right Course displays show the program title and option to set the
parameters.
C/O
key (push and hold for more than 1 second): enter the program menu.
N1
key: scroll to the next program menu.

C/O
key: save changes and exit the program menu.
Settings are saved in a non-volatile memory when you exit the configuration menu and the MCP
goes in stand-by. Following a description of the menu available in Configuration Mode.

EXPANSIONS
MCP737PRO3 comes provided with wide expansion capability through the DIN 5 pole auxiliary
socket (Figure1 “C”).
This allows you to connect and interface CPflight plug&play expansion. For further information
about modules refer to CPflight website.
AUXILIARY CONNECTIONS
WARNING! The use of auxiliary connector is intended for expertise users. To use these
auxiliary functions it is necessary to connect external pushbuttons and potentiometer. Do
not connect anything coming from any external power source or different by the following
indications; warranty does not cover damages due to incorrect wiring of any external device.
COM:
Common pole
for External A/T disengage and TO/GA
AT/DIS:
External A/T disengage can accept input from a pushbutton.
The pushbutton contact must be open in normal condition and close
only when pressed. Releasing the button the contact must return in
open condition, do not connect steady position switches (toggles or
similar) to this input. When pushing the button the A/T ARM switch
disengage independently from any other aircraft system condition.
EXTERNAL TO/GA:
External TO/GA can accept input from a pushbutton. The pushbutton contact
must be open in normal condition and close only when pressed, do not connect steady position
switches
to this input. The TO/GA function engaging depends by the aircraft condition and situation
(managed by the connected software).
EXTERNAL BACKLIGHT CONTROL:
External backlight control accepts input from potentiometer
or switch. Connecting a potentiometer you can regulate the backlight intensity brightness directly
from this input while connecting a switch is possible only to select ON/OFF.
1Kohm to 4,7Kohm 0,5W potentiometer is suitable for a typical setup. To use the external backlight
control set the related preference to “E” in the preferences setting (see “CONFIGURATION MENU”
section).
Important note: when the backlight is controlled through the external control input, it’s
status it result independent from any other MCP function.
FIRMWARE UPDATE
The MCP hardware is based on a flash memory microprocessor, on this device has been
developed one special program (bootloader) that allows to upgrade the firmware. When you install
the CPflight driver in the folder will be also installed a program (TCPIP_upgrade.exe) that has to be
used for the upgrade.
Upgrade the microprocessor is a very easy operation and can be done through your ethernet
connection.
Is necessary to upgrade the firmware time by time, to update new functions that are constantly
developed to improve functionality and compatibility with new products. New firmware release are
available at CPflight website at MCP737PRO3 page, section technical and documents. Download
this zip file and extract the included file into a temporary folder. Please pay attention to the
extension of the file: it must be an
hex
extension.
The revision number is progressive, so a higher number correspond to a latest version. Before to
proceed with the upgrade check the installed firmware revision number. You can see the installed
version in configuration mode (see related section) or at the MCP startup.
HOW TO UPGRADE
To proceed with
the firmware
upgrade, activating
the bootloader present in the microcontroller’s
flash memory, you have to power the MCP
pushing and holding pushed the CMDA button.
Then please run the program
TCPIP_upgrade.exe and verify that the TCPIP
parameters (TCPIP address and port) are the same used normally to communicate with your PC. If
not please modify it into the TCP upgrade window program.
At this point click on “Load” menu into
TCPIP_upgrade.exe menu bar and select the file
that you have already downloaded and extracted
into a temporary folder from the site.
Is important to be sure to select an hex estension
file. The file will be shown as MCPPRO2_xxx.hex
where xxx will indicate the firmware release. Now,
in the program menu bar, select the “Connect”
title
.
If all is
ok, in this menu will activate the “Erase”
title. At this point select “erase” to delete the old
firmware and prepare the microcontroller for a
new script. The erase operation will take few
seconds.
At the end of this process, always in the
program menu bar, will activate the option
“Program”.
Please select this title, it will appear a progress
bar that indicates the program progression. This
operation will take about two minutes to
terminate.
At the end it will appear a window that indicates
the end of the programmation. Close the
upgrade program and disconnect the power
supply from the MCP. Connect another time the
power supply to verify that in the IAS display
window of your MCP will appear the new
release number.
