Project Magenta FSUIPC Offsets

Public Version

For the newest online version of this document, go to www.projectmagenta.com/docs.html

Please send an e-mail (support@projectmagenta.com) with your unanswered questions or any hints you think may be useful to others. Thank you.

These offsets are FSUIPC offsets for communication with MSFS 98/2000 and 2002. You will find the FSUIPC SDK on www.schiratti.com/dowson.html

They are all 2 bytes long, unless otherwise stated.

To check whether the A/T is disconnected, use 0x310A bit 3 (as per FSUIPC documentation)

To interface to the MCP or FCU, ideally use the button commands as described in 0x4F2.

 MCP/FCU Throughpass (See MCPcodes at the end) (Read/Write)

Example: Write Value 33 to engage AP2 (K033 ELAN Code). Once read, the MCP resets the value to 0 and is ready for another read.
Only last three digits are used, you can use the thousands to indicate the key has been pressed again (state change), i.e. 4033 and 7033 do the same

DisableRemoteMCP must be set to OFF in the INI file for this to work.

 Glass Cockpit ND Modes (Write Only) (*was* Read as well)

Sending 100+(value) controls First Officer Display (e.g. 170 enables weather on Copilot ND)
Only last three digits are used, you can use the thousands to indicate the key has been pressed again (state change), i.e. 2150 and 5150 do the same

Please note, these commands go directly to the Glass Cockpit, if you do not want the MCP or FCU to override them, then please use the MCP commands in 0x4F2 or 0x5520.

 AP Mode 2 (Annunciator Standby Values) (Read Only)

Hex Value of anunciator Channels, 15 values possible per channel, encoded as follows:

Thrust Channel Standby Mode (Speed modes)
Vertical Channel Standby Mode (ALT etc.)
Horizontal Channel Standby Mode (HDG etc.)

0xThr * 0X100 + 0xVer * 0x10 + 0xHor

For a list of the anunciator values, please go to http://www.schiratti.com/docs/AircraftType.html, as the meaning varies according to the type file. This is also the case for AP Mode 3.

This value is just an anunciation, i.e. it doesn't set any mode!

 AP Mode 3 (Annunciator Values) (Read Only)

Autopilots Active (Bits 0 = none or any combination of 1, 2, 3 (bit 3), i.e. value 5 would be A/P 1 and 3 active)

Vertical Channel (ALT etc.)
Horizontal Channel (HDG etc.)

0xAuto * 0x1000 + 0xThr * 0X100 + 0xVer * 0x10 + 0xHor

This value is just an anunciation, i.e. it doesn't set any mode!

 CDU "Keyboard Interface" (2 bytes)

low byte, ascii character
high byte shift = Bit0, Ctrl = Bit1, Alt = Bit2 ... other bits must change if you have two same characters after the other...

. (period) = 190
/ (slash) = 191
+ (plus) = 107
DELETE = 46
CLR = 8

The space key is not supported for the time being

This can be used to write characters to the scratchpad of the CDU and to manipulate the LSK and function keys - FX keys from Ascii 112+(X-1)

Special ASCII
220 - automatic navaid selection/ autotune (no high byte = enable, shift = disable, ctrl = toggle)
(open to suggestions)

RCDU Extension: Setting bit 6 of the high byte, using the same rules as above, you can send keyboard commands to the RCDU. E.g. Sending “A” to the CDU is value 65, to the RCDU it is (256 * 2^6) + 65 = 256 * 64 + 65 = 16449 (this command will then of course be ignored by the CDU) Updated 14-12-2006
