104TX is a N-Tron networking series unmanaged industrial Ethernet switch. It is housed in a hardened, metal, DIN-rail enclosure, and is designed for use in mission-critical data acquisition, control, and Ethernet I/O applications. It is designed to solve the most demanding industrial communication requirements while providing high throughput and minimum downtime. It provides four RJ-45 auto-sensing 10/100BaseTX ports. The 104TX auto-negotiates the speed and flow control capabilities of the four TX port connections and configures itself automatically.
