Description
RJ3012 is an industrial-grade two-in-one converter with RS-232/485 interface extended through USB. It can easily connect RS-232/485 devices to a computer host with a USB interface.
This product has added anti-surge protection measures on the RS-232/485 end. Make your computer more free from the surge of RS-232/4 85 circuit, making it more suitable for industrial applications.
Compared with general modules, the module has the characteristics of small size, high sensitivity, long transmission distance, high communication rate, complete functions such as automatic communication protocol conversion and data transmission and reception control, etc. It is a high stability, low power consumption, and cost-effective. USB to serial port module, and adopts serial port connection method, which increases the stability of serial port data. It is widely used in attendance machines, IC card charging systems, industrial automation control systems, all-in-one card access control systems, parking systems, automatic banking systems, and public Automobile toll collection system, canteen selling system, highway toll station system, etc.

Features
All new chips are used! All new chips are used! All new chips are used!
Industrial-grade protection:TVS transient suppression protection, electrostatic ESD protection, surge protection, AB signal line short-circuit and short-circuit protection with the power supply (short-circuit does not burn)
The transmission distance can reach 1200 meters (tested at 9600bps)
Support the baud rate of 921600, which is much higher than 115200, and the baud rate is higher for paired mutual transmission
Multi-system support hot swap, support win98/CE/2000/2003/2008/XP/WIN7/WIN8/WIN10/VISTA/LINUX/MAC OS X system, USB interface can be hot swapped
Automatically distinguish and control the direction of data transmission, without any handshake signals (such as RTS, DTR, etc.) without jumper settings to achieve mode conversion, to ensure compliance with the existing communication software and interface hardware.
With TXD and RXD indicator lights
