Configuring the AFS 4500 dual screens

[Shawn McGinnis]

You will need the AF-ARINC module wired to one of the serial ports probably serial 4. This is what will drive the TruTrak.

Something like https://www.advancedflightsystems.co...%20Adaptor.pdf ignoring the 430 connections and switch.

Thank you Shawn. I do have an AF-ARINC module. I think the issue may be the configuration of the Serial Ports. PFD is configured as follows: Port 1 AVTN/AVTN, Port 2 TRFC/ICARUS, Port 3 SL-30, and Port 4 ARINC. The MFD configuration is: Port 1 AVTN/AVTN, Port 2 DISABLED, Port 3 SL-30 and Port 4 ARINC. Can you comment if I have these configured properly? Do I need to give you any additional information? I can post a pic of my configuration screens if that helps. Would be easier to do that in an email.
