RS232 TO RS485 BIDIRECT CONVERTER

Product Introduction

HXAD-Ⅲ type converter is a bidirectional interface between RS-232 and RS-485 Port converter, used between the host computer, the host computer and the microcontroller or peripherals A point-to-point, point-to-multipoint remote multi-machine communication network is formed to realize the mystery Response communication is widely used in industrial automation control systems, one-card access control systems, parking lot systems, self-service banking systems, bus toll collection systems, and canteen sales systems. Company employee attendance management system, highway receiving station system and so on. HXAD-Ⅲ type converter, can convert RS-232 serial port TXD and The RXD signal is converted into a two-wire balanced half-duplex RS-485 signal. no external Power can be directly stolen from pin 3 of the RS-232 port, while request to send (RTS) from pin 7 and data terminal ready (DTR) from pin 4 to HXAD-Ⅲ auxiliary Auxiliary power supply, automatic flow control so that you do not have to reset, hardware and installation very simple
