SimpleMotion V2 communication link and Argon drives use RJ45 connectors and cables as physical connection standard.
RJ45 is well known from Ethernet connectors and same cables may be used with SimpleMotion wiring.
Electrical properties
SimpleMotion V2 uses RS485 electrical serial communication standard for all data transfer. Some main benefits of using RS485 are:
- Low wire count, only 2 signal wires + ground needed
- Bidirectional data transfer (receive & transmit) in one wire pair
- Multidrop buses possible (up to 32 devices in single serial link)
- High reliability due to differential signaling
- High data rates and long cable lengths possible
- Easy to interface even from smallest microcontrollers with UART
