Switching MCDU without MCP

[cvg]

Hello,

I got the Airbus drivers working in the Aerosoft Airbus and I'm controlling the right-hand MCDU with my 737CDU vs3.
In the instructions you state you can switch to the left-hand MCDU by using "FD_right switch acts as a Switcher between usage of MCDU left and MCDU right".

However, as I do not have the opencockpits 737MCP (I'm using the CPFlight 737MCP), how can I switch to the left-hand MCDU?

Thanks,
Cyrille

Hi,

One way to do it is to configure a specific hotkey in FSUIPC and make that initiate the swithing.
The hotkey should then toogle the offset 66C0 bit 0.

You must then edit the script file

part of origninal script:
Var 5 , name MCDU1_ON Link IOCARD_SW Device 15 Input 14 Type I // With this input you select active MCDU

{
IF v5 = 1
{
&SETUP = 0
}
ELSE
{
&SETUP = 1
}
}

to
Var 5 , name MCDU1_ON Link FSUIPC_IN Offset $66C0, Length 1 // With this input you select active MCDU

{
IF v5 = 1
{
&SETUP = 0
}
ELSE
{
&SETUP = 1
}
}

and recompile

Thanks for the guidance Roar. I tried to set it up, but I still cannot control the left MCDU.
i'm testing using F12 as the key to switch MCDU.

Probably there something wrong in my FSUIPC setup, however as I no programming experience can you point out what I'm doing wrong? See my current setup.

Thanks

Do it with ToggleBits 66C0 1

Thanks Roar, works perfectly now!
