Overview of the system
- Embedded DEC PDP-11 computer collects Aircraft maintenance information.
- This data is transferred via a serial/RS232 connection to a Windows PC running WinWedge Pro.
- WinWedge Pro feeds the data real-time into the CMDI software via Dynamical Data Exchange (DDE).
- This displays the maintenance information in real-time and also drives a cockpit CMDI (Display) unit.
Real-time Serial Data Via DDE to Windows app
WinWedge Pro is installed on a PC is set to receive serial data from an embedded DEC PDP-11 computer in an aircraft maintenance trainer. The DEC Assembly program generates the “Global” flags and some numeric data. WinWedge transfers these flags and data to the Color Multi-function Display Indicator (CMDI) simulation software via a DDE (Dynamic Data Exchange) link. WinWedge fully supports transferring serial data via DDE to other DDE supporting Windows applications such as the CMDI software. The Windows-based CMDI software drives a simulated cockpit 4×4 CMDI (Color Multi-function Display) Unit that is used to display maintenance data.
Recommended as No Programming or Custom Drivers Required
According to a Computer Systems Specialist at the aerospace company, “WinWedge was easily installed and configured to receive the serial data and transferred that data to my application program, without my having to program/code drivers”.
- Ability to input real-time data sent via RS232 from an embedded computer into the CMDI Windows simulation software – without custom programming!
- Very Easy to set up and use
