Selection and installation notes
It extends USB connections to scanners, dongles and keys in control cabinets and kiosks, with a seven-port sibling, the UPort 407, listed alongside it.
On the practical side, mounting is listed as wall mounting; din-rail mounting (optional); the housing is aluminum; the stated MTBF is 1,490,340 hrs; the warranty period is 5 years. Treat the MTBF as a manufacturer prediction under its stated method, not a guarantee for your site.
What to confirm before ordering: the number of ports, the -T temperature option and whether the supplied adaptor suits your mains. Our team in Muscat works from the exact code on your enquiry, as an independent supplier.
Related models in the UPort 404 family
The Moxa product list shows these models in the same family page (4 entries): UPort 404, UPort 404-T-W-O-ADAPTER, UPort 407, UPort 407-T-W-O-ADAPTER. Suffixes such as -T generally mark wide-temperature versions and fiber suffixes (M, S, MM, SS with SC or ST) mark the connector and fiber type, but the order code printed on the datasheet governs.
Planning notes for the hub: it connects to the host through a USB Type B port and offers four downstream ports at USB 2.0 high speed (480 Mbps) with 1.1 fallback at 12 Mbps, draws 1.3 A at 12 VDC, and uses an aluminium housing with wall mounting and an optional DIN-rail kit. The EMS table lists 8 kV contact and 15 kV air ESD immunity, which is useful for hubs mounted near operators. Total the current drawn by every connected dongle, scanner or key against the hub supply, and keep cable runs within standard USB 2.0 limits; a longer run needs an active extension or an Ethernet-based alternative such as a device server.

About brand
Moxa is the Taiwanese maker of industrial networking equipment: Ethernet switches, serial device servers, protocol gateways, media converters, secure routers and remote I/O. It was founded in Taiwan in 1987 and started with serial communication products before moving into industrial Ethernet. It is headquartered in Taipei.
Seven Star LLC is an independent supplier in Muscat. We list Moxa switches, serial servers, gateways and converters, and supply them to control system integrators, utilities, oil and gas and building automation projects in Oman and the GCC by exact model.

The choice between switch types follows the network. An unmanaged switch simply forwards traffic and suits a small, isolated panel. A managed switch adds redundancy protocols (Moxa's Turbo Ring recovers a broken ring in milliseconds), VLANs to separate traffic, port mirroring and alarms, which a SCADA or DCS network needs. The suffix on a Moxa model also matters: "-T" means a wide operating temperature range (typically -40 to 75 °C), which is the safe choice for outdoor cabinets in the Gulf summer. "-MM-SC" or "-S-SC" means multi-mode or single-mode fibre with SC connectors.
Where Moxa products are used
In Oman and the GCC, Moxa equipment connects RTUs, PLCs, meters and protection relays in oil and gas fields, electrical substations, water and wastewater SCADA, transport, and building and energy management systems.
Ordering Moxa products: what we need
Send the complete model including all suffixes (for example EDS-508A-MM-SC-T), the quantity, and for fibre models the fibre type and distance. For gateways, tell us which two protocols need to be linked.
