Moxa’s integrated serial device server solutions combine a variety of functions in an all-in-one design that combines a managed Ethernet switch and a device server in a single device. This design can fulfil multiple project requirements in a fraction of the space required for separate devices, simplifying both device configuration and operational and maintenance costs.
