Networking Module USR-TCP232-T2, is a new, small volumes of serial-to-Ethernet module, which is a RJ45 Ethernet ports can be achieved between the direct and TTL serial transparent data transmission equipment. And it can be applied by the level conversion circuits 232 and 485.

T2 module low-power, full-speed operation consumes only a small current. M0 series equipped with 32-bit processors running at speeds as fast and efficient. Meanwhile module diverse functions to better meet customer needs.

T2 module is simple, and compatibility. Adding new features based on the still compatible with K1 and T24 series set protocol for the old user convenience. At the same time, it increased protocol similar to K3 and set M4, the use of other products the customer protocol settings, just a simple adjustment can be applied to T2.
