JMT USR-K7 Low Cost TTL UART to Ethernet Module 10/100Mbps Super Port Ethernet to Serial Module Support Modbus RTU to Modbus TCP with RJ45 Port (10PCS)

*Easily USE* - K7 is a module that can realize data transparent transmission between the Network and TTL serial port, which is equipped with ARM cortex-M4 processor. No need to care of the details, the module realize the protocol converse.Parameters can be set in the software and webpage, configure one time and save forever.
*Virtual COM* - Solves the problem that PC software as serial port can not communicate with networked devices.Many traditional serial port devices does not have networking capability. USR-K7 module integrated TCP/IP protocol stack can provide the solution of network communication between serial device to server via network based on socket to improve the level of industrial automation.
*Disconnection Identification, Automatic Connection.* - Can easily identificate the dead links and auto re-connection to prevent data loss due to power outages and disconnections. Custom built-in web page, support Web to Serial.Design built-in web pages according to project requirements,realize web page control, web page data acquisition.
*Modbus Gateway* - Polling mechanism can effectively solve the problem of congestion caused by data concurrency.(firmware 3009 or higher).Supports Modbus RTU to Modbus TCP.
*Function* - Supports TCP server/client, UDP server/client,https client, Virtual COM.Supports 10/100Base-T(X) self-adaptive Ethernet interface.Supports flow control CTS/RTS, XON/XOFF.Hardware watchdog;TI Cortex M4 Solution;MQTT/SSL special firmware.
