Nox A1 Online - Sentec Setup

The Sentec™ has a serial output and a LAN output on the back of the device. It is therefore possible to connect to the Nox Sleep System using two methods

  1. Via Nox C1 Access Point using a standard RS-232 to 3.5mm jack serial cable from the serial port
  2. Connecting the Sentec LAN output to the same local network as the Nox C1 Access Point is connected to.

The two setup possibilities for the Sentec can be seen on the images below:
