Connectors

🔌
USB-B
Connection to PC. Supplies power and provides the virtual COM port (FT232RL).
🔗
Mini-DIN-6 — Azimuth (J1)
Connects to the AZ port of the DX(A/C) rotor clock. Carries potentiometer signal and relay drive lines for CW/CCW.
🔗
Mini-DIN-6 — Elevation (J2)
Connects to the EL port of the rotor clock or dedicated elevation unit.

Compatible hardware
