RS485note
- The purpose of this application note is to describe the main elements of an RS-422 and RS-485 system. This application note attempts to cover enough technical details so that the system designer will have considered all the important aspects in
485
- 422 and 485 Standards Overview and System Configurations. ANSI TIA/EIA-422 and TIA/EIA-485 standards, commonly known as 422 and 485, respectively. Techniques for impedance matching to minimize line reflections in several applications are presen
Modbus_over_serial_line_V1_02
- This document describes the MODBUS over Serial Line protocol. MODBUS Serial Line protocol is a Master-Slave protocol. This protocol takes place at level 2 of the OSI model. A master-slave type system has one node (the master node) that issues exp
