1PC TLC485 serial port enhanced RS232/RS485 bidirectional converter 3onedata

Features
◎ Send RS-232 data (TXD) and receive data (RXD)
The signal is converted to a balanced half-duplex RS-485 signal
◎No need for external power supply, get power from RS-232 port TXD, RTS, DTR signals
◎The power consumption is extremely low, which is equivalent to the power consumption of ordinary light-emitting diodes during static operation, which can be called truly "passive"
◎Using automatic data flow control technology to automatically determine and control the direction of data transmission
◎Point-to-multipoint communication, support 32-point polling environment (128 points can be customized)

Introduction
TLC485 is a low-cost interface converter that converts RS-232 signals to RS-485 signals.
Interface conversion products. This product directly takes the power supply from the serial port of the device (such as the COM port of the computer) without external power supply. With small size, transmission distance
Long distance, high speed, stable performance and other characteristics.
TLC485 adopts a pocket-sized shape design, adopts DB9/DB25 universal serial interface, and is equipped with pluggable terminal blocks, which is flexible and convenient to use.
Widely used in point-to-point communication, industrial distribution system, various remote control measurement systems, POS cash registers, banking, insurance, securities, canteen sales
System, traffic charging system, industrial distributed control, various PLCs, data watt-hour meters, gas meters, etc.
