Let me be clearer:
Back in the day, we used Moxa boards because there was nothing else. Do you own a USB to serial adapter? https://www.amazon.com/s?k=usb+to+serial+adapter&ref=nb_sb_noss

About $5-15 from your favorite supplier. That and an old PC running Windows and Aeroadmin software 900100.net gets you remotely to the box that runs the terminal software to talk to the Strategy. I pay $125 or so a year for my copy of Aeroadmin, but it beats driving 100 miles or more to administer a system when the Raspberry Pi goes stupid.

Aeroadmin is actually "free" for short use. It can be configured to be running all the time and you access it from your local machine running the software. You put in your 9 digit code to connect remotely and provide the password to get in. At the remote PC, it's a setting to allow access.
