On the HD-15 connector (used to connect to the DR-1X) there are unbuffered GPIO pins for:
Audio:
Ground and Power (The UDRC and Raspberry Pi are powered from the repeater) The mini-din 6 will follow amateur radio convention, however the control pins will be buffered because of potential voltage differences. More advanced topics will follow basic documentation.
