Detailed Answer
RS485 and CAN are both industrial field buses: RS485 uses differential signals, is simple and cheap, and is half-duplex; CAN supports multi-master communication with strong real-time performance and good anti-interference. The receiver of an industrial remote control can communicate with PLCs or host computers via RS485/CAN for remote monitoring and parameter configuration. The LIDER LD series offers optional RS485 output; XINGJIA offers optional CAN bus. For companies that need networked equipment monitoring, choosing a model with bus support is a smart choice.
| RS485 | Differential / cheap |
| CAN | Real-time / anti-interference |
| Application | Networked monitoring |
Note:Add bus interfaces when you have networking needs to reserve expansion capability.
