NPORT S8455I-MM-SC - 4 RS-232422485 ports, 3 10100BaseT(X) ports, 2 100M multi-mode fiber ports with

Moxa’s integrated serial device server solutions consolidate a wealth of features into an all-in-one design that combines a managed Ethernet switch and a device server into a single device. This design can satisfy multiple project requirements in a fraction of the space needed for separate devices, and both simplifies device configuration and reduces operational and maintenance costs.

4 RS-232/422/485 ports, 3 10/100BaseT(X) ports, 2 100M multi-mode fiber ports with SC connector, 15 KV ESD, 12 to 48 VDC, 0 to 60°C operating temperature
