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.

ENCODERS: set the preferences.

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.

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

FIRMWARE UPDATE

V/S

Right Course

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

Port

ALT

the CPflight driver in the folder will be also installed a program (TCPIP_upgrade.exe) that has to be

used for the upgrade.

HDG

Upgrade the microprocessor is a very easy operation and can be done through your ethernet

briG

(from 0 to 10)

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

HDG

this zip file and extract the included file into a temporary folder. Please pay attention to the

CtrL

(I,E,ICS)

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.

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.

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.

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

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.

At the end of this process, always in the

program menu bar, will activate the option

"Program".

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.
