RS485 data acquisition: a new chapter
02 October, 2013 by Steve Huang and Wayne Chen, Moxa IncRS485 and ethernet are two commonly adopted communication interfaces used in data acquisition and control systems. Ethernet I/O devices are generally considered more sophisticated, RS485 I/O devices may be sufficient for budget-conscious system integrators. Nonetheless, there are still ways device manufacturers can improve on the lasting legacy of RS485 data acquisition devices.
