It supports speeds of up to 56 Kbps for data (56K down, 36.6K up) and 14.4 Kbps for fax, complying with common transmission standards such as V.92 and V.90, allowing it to be used both for dial‑up Internet access in environments without broadband and for sending and receiving faxes directly from the computer. Its dongle‑type format in black has compact dimensions of approximately 27 mm wide and an integrated 32 cm cable, making it easy to carry in backpacks or briefcases with a laptop. It includes a data LED indicator to visually check connection status and comes with a setup guide included, enabling quick installation even for non‑specialist users. It is compatible with a wide range of operating systems, including Windows 7, 8, 8.1, 10 and Windows Server (2008 R2, 2012 R2, 2016, 2019), as well as Mac OS 10.9 to 10.10, making it suitable for various professional environments, including office PCs, POS terminals or CMS systems. The device operates within a operating humidity range from 10% to 90% and has CE, FCC, RoHS, REACH and TAA certifications, confirming compliance with safety, electromagnetic compatibility and hazardous substances regulations. Overall, the StarTech USB56KEMH2 is a reliable, compact solution to add a USB modem and fax to modern systems that lack an integrated RJ‑11 port.
