USB-USB NULL Modem (CDC)

The 8086 USB-USB NULL Modem (UUNM) is a back-to-back USB to Serial converter using USB CDC Serial - meaning drivers are already built in to most modern operating systems (Linux/Windows 10/Mac OS X/Android) so you can just plug n' play!

Uses

The USB-USB Null Modem can be used to set up additional remote consoles between servers, file transfer, SLIP/PPP networking, heartbeats and more.

What makes it special?

Whilst there are similar USB-USB Null Modems, many have bulky built-in cables or need drivers. This USB-USB NULL Modem adaptor uses existing cables and uses built-in drivers.

Note: Micro-USB cables are not supplied and must be purchased separately.
