Your order contained Digirig and CAT capable MiniDin10 cable and no other transceiver cables. MiniDin10 cables are used with Yaesu FTM radios with RS-232 serial port. That being your first order I figured the probability is high that you intend to use the kit with Yaesu FTM so the swap was done as a courtesy to save you the potential hassle and frustration.
Here is the relevant discussion on the topic of FTM:
If my assumption was incorrect, I apologize for that and will be happy to arrange the replacement or instruct you on changing the serial port configuration.
PS: I also received all your emails re. this matter.
