USR IOT USR-TCP232-T2

The USR-TCP232-T2 is a brand-new, compact serial-to-Ethernet module capable of transparent data transmission directly between an RJ45 network interface and a TTL serial port. It can also be applied to RS232 and RS485 interfaces via level-shifting circuits.

The T2 module features low power consumption, drawing only minimal current at full operating speed. Equipped with an M0-series 32-bit processor, it delivers fast processing speed and higher efficiency. Its diverse functionality further meets the varying needs of customers.

The T2 module is easy to operate and offers strong compatibility. Building on new features, it maintains compatibility with the T24 series configuration protocol for the convenience of existing users. It also introduces a configuration protocol similar to that of the M4 series, allowing customers migrating from other product lines to apply it to the T2 with only minor adjustments.
