USR-TCP232-306 is a serial RS232, RS485 or RS422 to Ethernet converter, used for data transparent transmission. It is a low-cost serial device server, whose function is to realize bidirectional transparent transmission between RS232, RS485 or RS422 and Ethernet.
USR-M511 is Modbus gateways that query Modbus RTU/ASCII slave and display data in internal webpage. It also supports reply the querying from Modbus TCP Master. USR-M511 provides a flexible method to control and monitor your Modbus RTU/ASCII devices.
This is a serial TTL to Ethernet module, used for data transparent transmission. USR-TCP232-ED2 is a triple serial ethernet module, which supports 3*TTL working at the same time. It is based on Cortex-M4 solution and its basic frequency is up to 120MHz. And the internal of the module integrates TCP/IP protocol stack.
USR-TCP232-T2 is a tiny size serial Ethernet module which can realize bidirectional transparent data transmission between TTL and Ethernet. It can also be applied in RS232/ RS485 by level shift circuit. USR-TCP232-T2 is based on Cortex-M0 core. It has characters of low power, fast speed and high efficiency.
