Problems with MCP423a

[Pim van Vrijaldenhoven]

The intermediate mcp423a program is causing severe problems in my setup I am using the CPFlight MCP (USB version), together with the latest versions of PFD, CDU and pmSystems.

What happens is that in mid-flight the MCP program freezes and the simulator no longer responds to the MCP commands. In fact, it is so bad, that even with the Windows Task Manager I cannot kill the program.

There is probably a conflict with the new MCP737-PRO commands.

Best regards,

That´s interesting. I have a similar problem with my CP Flight / PM MCP setup: After a certain time, it seems like the communication between the hardware and the software MCP simply stops. I then have to re-start the PM MCP, which also leads to a re-boot of the CP Flight MCP.

But I have seen this since several builds of the MCP.

I´ve also using CPFlight MCP USB-Version and have no problems since using PM.

Sorry to say that I do have problems (see my thread http://www.mycockpit.org/forums/showthread.php?t=10811) though they are not that big as the others seem to experience.

I have a problem regarding the BAT status:
MCP doesn't react on BAT OFF, it's always ON.
I have FDS G1 hardware.
PM is informed about that.

Hi JWS,

I don´t think that this issue is an PM trouble. I know exactly this failure and changing Altitude to 50000 without PM.

On beginning of my Homecockpit I used PMDG 737-800 with CPFlight MCP then this errors occured from time to time. Sometimes by pressing v/s the plane goes to -6000ft/m, sometimes in descend the altitude changed to 50000.

Since using PM on different computers this errors are gone. Never seen this issues again.

Just got a response from Enrico about my subject:

>We used to switch off the MCP physically using a special command which switched the hardware off altogether. This caused problems with some expansion boards.

We had to replace this with a command which just switches off the lights but kept the MCP hardware running in the background.

The G1 does not handle that command. <

They will find a solution.

Good PM support !

Roland,

I used to have W98SE with PM MCP and CPFlight on a FS2002 Server. No problemo.
Then bought a new PC (XP Pro), with FS2004 and PM MCP + CPFlight on it. Then trouble began. As said in other threads it's only when both are in use. CPFlight (and others) specifically advise to run both on the same pc as FS.

Guys..

I must reiterate the fact that PM does not regularly monitor these forums.

Please send your comments and support requests via email to: PMSUPPORT

Trevor,

been there, done that. PM hasn't been able to find a solution yet. Like to know if I'm the only one with this problem. This is a users forum, isn't it?
