Product Description


USR-TCP232-302, USR-TCP232-304 and USR-TCP232-306 are cost-effective serial to Ethernet converter. They adopt Cortex-M0 solution,
which has a main frequency up to 48MHz, providing fast transmission speed. Equipped with RS232/RS485/RS422 serial port and 10/100M
Ethernet port, those products can connect to variety of serial devices to achieve transparent transmission via simple
configuration to save manpower and shorten the development cycle. These products are widely used in smart traffic, unattended
Weighing, manufacturing industry etc. USR-TCP232-302, 304 and 306 are identical in software features, they both support
transparent data transmission, Modbus gateway, user-defined webpage, heartbeat packet, registration packet, index function etc. In
hardware, TCP232-302 is RS232 to Ethernet converter, TCP232-304 is RS485 to Ethernet, TCP232- 306 supports RS485/RS232/RS422, but
RS485/RS232/RS422 can’t work at the same time.
