Configuration in Noxturnal:


To use a Nox W7-Link, you must create a specific recording type.

In Noxturnal, open Devices > Recording Types and create a new Nox T3 or Nox A1 ambulatory recording type. Use the left column to add devices, including the auxiliary device you want to connect with the Nox W7-Link. Save this newly created recording type by clicking on OK.

When configuring an ambulatory study, select the appropriate recording type.

If using the Nox T3, type the 9-digit serial number found on the label of the Nox W7-Link.

If using the Nox A1, type the 12-digit BDA number found on the label of the Nox W7-Link.

Physical setup:

Power the Nox W7-Link using the power supply provided in the Nox W7-Link kit.

Starting an ambulatory study:

Turn on the auxiliary device. Turn on the Nox recorder if you selected a manual start or wait for the device to start automatically if you selected a scheduled start.

There are two LEDS on the Nox W7-Link, one blue and one green. During the recording, both should be blinking. Refer to the following table for LED status.
