Overview
The USB-RS485B module provides an easy to use RS485 interface by means of a Virtual Com Port on the users system. There are no command structures, whatever is sent to the Virtual Comm Port is automatically converted to RS485 and vice versa.
The module is completely self powered from the USB bus.
Modbus is a standard and well supported protocol for industrial applications. The USB-RS485B is an inexpensive way to control and monitor Modbus devices by using a Modbus master program on your PC.
ST485 RS485 driver chip
The ST485 used on the USB-RS485B module features reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps.
Automatic Bus Turnaround
The USB-RS485B will automatically control the ST485 to seemlessly switch the output drivers on for transmission or off for reception of data.
