USB Deviceserver User Manual macOS General Information
1.1 Product
Purpose
UTN servers comprise USB Deviceservers and USB Dongleservers. As USB device servers, they provide non-net-
work USB devices (e.g. USB hard disks, USB printers, etc.) via TCP/IP network. The USB devices are connected to
the USB ports of the UTN server for this purpose. The UTN (UTN = USB to Network) functionality and the corre-
sponding software tool 'SEH UTN Manager' then establish a virtual USB connection between USB device and cli-
ent. The USB device can be used as if it were connected locally.
System Requirements
The UTN server has been designed for use in TCP/IP networks.
The SEH UTN Manager can be used in the following systems:
• For Windows 10 or later, Windows Server 2012 or later
• For macOS with SEH UTN Manager Version 3.3.x
- 10.15 (Catalina)
- 11 (Big Sur)1
• For macOS with SEH UTN Manager Version 3.4.x
- 12 (Monterey)2
• For Linux (Ubuntu 18.04/20.0.4, Debian 9/10/11, CentOS 7/8, CentOS Stream 8, Oracle 7/8, RHEL 7.4/8.4, Open-
SUSE Leap 15.3, SUSE Linux Enterprise Server 15) 3
• IPv4 TCP/IP network
• IPv6 TCP/IP network
The SEH Product Manager can be used under the following systems:
• Microsoft Windows (32/64-Bit; Windows 10, Windows 11 , Server 2012 R2, 2016, 2019, 2022)
• macOS 10.15 (Catalina), macOS 11 (Big Sur), macOS 12 (Monterey)
• IPv4 TCP/IP network
• IPv6 TCP/IP network
This document describes usage under macOS environments. Information about the usage in other environments
can be found in the relevant system-specific User Manual. More details can be found in chapter ’Documentation’
 3.
1. macOS 11.x (Big Sur) only limited USB device support.
2. Installer supports only „complete version“. More details can be found in chapter ’Administration via the SEH UTN
Manager’  11.
3. A successful installation cannot be guaranteed due to the variety of Linux systems! The installation must be car-
ried out under your own responsibility.
