Embedded 15 kv ESD surge protection all the serial port

Intuitive menu in Chinese interface, it is more simple installation configuration

232/422 / RS - 485 serial port can be flexible combination, type conversion depend entirely on the software

Real COM port driver under WINDOWS, can support up to 6 hosts at the same time to open the same serial port

Support TCP and UDP Socket, each serial port can support 6 different session mode

Provide UNIX and LINUX fixed TTY driver

Support to set aside the PPP/SLIP is dialed

Support the TTY, character terminal can be connected the banking system

With the method of transparent transmission, user need not guidance complex TCP/IP protocol

AES encryption (optional), the user data to get reliable security

Many levels of power supply design, meet the power demand of different field environment
