Product Attributes

Introduction

• USR-TCP232-S2 is a new, compact serial-to-Ethernet module that enables transparent data transmission between a network port and TTL serial interface. It can also be applied to RS-232 and RS-485 interfaces via level-shifting circuits.
• The S2 module features low power consumption, drawing minimal current at full operating speed. Powered by an M0-series 32-bit processor, it delivers fast processing speed and higher efficiency. Its diverse functionality better meets customer requirements.
• The S2 module is easy to operate and highly compatible. While introducing new features, it remains backward compatible with the configuration protocols of the K1 and T24 series, ensuring convenience for existing users. Support for configuration protocols similar to the K3 and M4 series has also been added, allowing customers migrating from other product lines to adopt the S2 with minimal adjustments.
