USB-232/ TTL Isolation Module

Description:

The USB interface is hot-swappable, and multiple systems support hot-swap, supporting win98 / CE / 2000/2003/2008 / XP / WIN7 / WIN8 / WIN10 / VISTA / LINUX / MAC OS X systems.

USB to RS485 Converter and all kinds of 485 interface docking, transmission distance up to 1200 meters (tested at 9600bps), support baud rate 921600, much higher than 115200. Industrial CH340 chip, automatically identify and control the direction of data transmission without any handshake signals (such as RTS, DTR, etc). Mode transition can be achieved without jumper settings, ensuring compliance with existing communication software and interface hardware.

TVS transient suppression protection, electrostatic ESD protection, surge protection, AB signal line short circuit and power source short circuit protection (short circuit does not burn), with TXD, RXD indicator.
