Specialty Ethernet Module., Interface: Two RJ-45 10/100 Mbps auto-sensing ports connected via an internal switch (daisy-chain capable), utilizing a single IP address., Protection (Suffix "CA"): Features conformal coating, a protective layer that guards internal circuitry against humidity, dust, and chemical contaminants., Slot Requirements: Occupies on a universal RX3i system base and communicates via the high-speed .One SlotPCI bus, Power Consumption: 840 mA at 3.3 VDC and 614 mA at 5 VDC. The module functions as a bridge between the RX3i controller and various Ethernet devices using the four-layer TCP/IP stack:, SRTP (Service Request Transport Protocol): For communication with host computers running programming software or other GE-heritage control systems., Modbus TCP: Operates as both a to interface with third-party devices.Client and Server, EGD (Ethernet Global Data): Facilitates periodic data exchange for deterministic, high-speed communication between multiple controllers.
