Possible to drive a Tally UMD DB9 port from an ESP32 or Raspberry Pi device? #3
Description
Possible to drive a Tally UMD DB9 port from an ESP32 or Raspberry Pi device? Looking for example of how to physically connect either an ESP8266 or ESP32 micro-controller or even a Raspberry Pi?
I have a Andycine C173S broadcast monitor that I want to control the tally status on, via ESP microcontroller or Raspberry Pi device. Looking for assistance on how one might complete the physical connection?
