Flight Deck Solutions (FDS) makes a high-quality Ethernet-ready CDU that can connect to PSX via a network. The user manual is geared mostly towards users who have a switch and router for their flight-simming gear, with each networkable component connecting to the switch, but it is also possible to connect the CDU directly to your PC via an Ethernet cable. That option isn't covered as extensively in the manual. Therefore, the following step-by-step guide may be helpful if you want to connect the CDU directly to your PC.

Disclaimer: This is how I did it on my Windows 10 PC. It's possible that you have a configuration that won't work with the instructions below.

Acknowledgements: Many thanks to PSX users Jeroen Hoppenbrouwers and asboyd who helped me get off the ground with this.

1. Connect three cables to the CDU: 12V power, HDMI to your PC's monitor's output, and Ethernet to your PC's Ethernet jack.
2. In Windows 10, go to Settings > Network & Internet > Ethernet > Change adapter options.
3. Right-click on Ethernet, select Properties.
4. Click on "Internet Protocol Version 4 (TCP/IPv4)" and then click on Properties.
5. In the window that opens, select "Use the following IP address" and enter
6. Subnet mask will auto-populate with, leave this as-is.
7. Leave "Default gateway" and the DNS server addresses blank.
8. Hit OK and close out of these windows.
9. Perform a hard reset of the CDU hardware according to the instructions in the manual.
10. Open a browser and input the address You will see the FDS Configuration Portal.
11. In the Configuration Portal, click on Settings. Rename the device if desired (but don't use any spaces).
12. Click "Save configuration." The device will reboot.
13. Download, install, and run the TekWorx Limited interfaceIT Module Manager (the download URL is in the FDS user's manual).
14. Click "Add" and add your CDU (you'll see the name from step 11 above).
15. On "Assignment," specify Left, Right, or Center.
16. On "Available Modules," select AEROWINX Precision Simulator.
17. Click Save. You are finished installing the CDU.

To set it up within PSX, you will need two instances of PSX that are networked together.

18. Start one PSX instance and make it the main server. You'll see the CDU connect right away as a client.
19. Start another PSX instance, and make it a client.
20. Resize Layout 1 on the client to just about the size of the CDU screen, and focus it on the CDU display. Drag this layout to the screen of the hardware CDU, and finish resizing it. In PSX, on Instructor > Preferences > Screen, you will probably want to select "EFIS/EICAS/CDU bezels removed" and de-select "Show title, border, and buttons on flight deck frame" and "Show info tags." Also de-select "Allow paper sheet simulation."
21. If the window is black, you can go to Instructor > Preferences > Basics and select "Allow frame stretching across multiple monitors."
22. When the size and alignment are good on the CDU, go within PSX to Instructor > Layout > Settings and copy all properties of Layout 1 to the other Layouts. Save this as a 9-pack, called "CDU" or something like that.
23. To finish setting up the client, de-select Audio and USB and save a new .pref file in PSX that will start as a client with your new 9-pack; name it something like CDUClient.pref. More details on networking instances of PSX can be found here: https://aerowinx.com/board/index.php?topic=2999
24. If you haven't done so already, get rid of the Windows taskbar in the CDU. This is done in Windows Settings > Personalization > Taskbar. Turn "Show taskbar on all displays" to Off.

You should now be good to go! PSX will send commands for lights like EXEC and DSPY to the CDU, while the CDU will send appropriate keypresses to PSX. And the FMC output will be on the CDU's monitor. It works well!
