IMPORTANT INFORMATION > DPC-20 PROGRAMMER 
  • Hardware Type: PC USB-C to 3-pin (PWM/TTL) and 4-pin (RS485/CAN) interface.
  • Capable of configuring and testing HITEC digital servo actuators.
  • Compatible with various control methods (PWM, RS485, CAN), offering a seamless transition from legacy DPC-11, DPC-485, and DPC-CAN units.
  • Different servo actuator series require dedicated UI programs due to variations in communication protocols.
  • Ensure you connect the appropriate power supply to the DPC-20 for the connected servo actuator.
  • For servo actuators (5/7 Series, 9 Series, D/MD Series), connect to the 3-pin port on the DPC-20, and connect the power supply to the BAT- and BAT+ pins on the 4-pin port, paying careful attention to polarity.
  • DPC-20 Wiring Diagrams are located on the DPC-20 UI HUB DOCUMENTATION.
