RS232 to RS485 Serial Protocol Communication Data Module Converter Master O8H8

Description

RS232 to RS485 Serial Protocol Communication Data Module Converter Master O8H8
The converter of the two-way interface between RS232/RS485 converters is used between main control machines. The main control machine and the microcontroller or peripherals form a point-to-point, point-to-multipoint remote multi-machine communication network to realize multiple machines Response communication communication is widely used in industrial automation control systems.
all-in-one cards, access control systems, parking systems, self-service banking systems, bus toll systems, canteen sales systems, company employee attendance management systems, highway toll gate systems, etc.
The RS232/RS485 converter can convert the TXD and RXD signals of the RS-232 serial port into two-balanced half-duplex RS-485 signals. Without external power supply, it can steal electricity directly from pin 3 of the RS-232 port, and request to send (RTS) by pin 7 (RTS), and the 4-pin data terminal is ready (DTR) to provide auxiliary power to HEXIN-III. Automatic flow control does need to be renewed Setting up the hardware and installation is very simple
