Have you ever had problems to connect several master devices in a Modbus RTU network or just to synchronize RS485 lines with different baud rates ? Serial Master Multiplexer SMM-01 is created particularly for this purpose. It connects 2 master devices with a slave device over a RS485 or RS232 line and synchronizes the requests in such a way that avoids all possible collisions. There is a galvanic isolation between inputs, output and the 24 VDC power supply.
