Base setup help needed for PMDG 737NGX, Homebuilt MCP using IOCards and SIOC.

Looking for help with SIOC communicating with PMDG 737 NGX using IOCards for Homebuilt MCP.

I have completed the assembly of the MCP. In Both FS9 and FSX the SIOC .ssi scripts are working fine.

Newly installed NGX and created SIOC Script to test functionality of a basic switch input for Flight Director. Changed the FSUIPC Offset to $6533, reloaded SIOC no joy. Revert back to the default FSX 737, swap out the .ssi and everything works...this is without restarting the simulator.

Last night I reinstalled in the software in the following order: FSX, FSX-SP1, FSX Acceleration, PMDG 737 NGX and FSUIPC 4.853. Did not reinstall SIOC (4.2B2) as it is working with both FS9 and FSX (under new installation).

Confirmed / added to the 737NGX_Options.ini

Please help! What am I missing to get NGX to accept commands? Suggestions or guidance will be appreciated.

Here is a copy to the NGX SIOC Script I'm using...

VAR 1 Link FSUIPC_INOUT Offset $6533 Length 2 // Autopilot F/D Flight Director CPT

VAR 2 Link IOCARD_SW Input 9 Type I // Autopilot F/D Flight Director CPT

{

IF V2 = 1

{

V1 = 1

}

ELSE

{

V1 = 0

}

IF V2 = 1

{

V3 = 1

}

ELSE

{

V3 = 0

}

}

VAR 3 Link IOCARD_OUT Device 0 Output 15 // LED MA Captain
