Description
Bi-directional connectors convert of converter is mainly used between main controllers. Point to point and point to points remote telecomunication internet is constructed between the main controller and single panel machine to realise multi-machine recall telecommunication, which is mainly used in industrial automatica control systems, one card universal systems, access controller systems, car parking systems, self-service banking systems, bus charging systems, restaurant systems, personnel attendance systems and road charging systems.
This converter can transfer the TXD and RXD signals of RS-232 serial port parallel half duplex RS-485 signal. No need to get through the power, it can steal the electricity from the 3 pin of RS-232 interface and at the same time, after 7 pin's requirement of RS-232 sending RTS, 4 pin data terminal prepares DTR to help supplying the converter. Automatically process control make you need to reset and make a easy application of the hardware and software installation.
