Introduction
The Nox W7 LINK KITs come in three different versions and can be
used with the Nox recording devices when configured for an ambulatory
study. Note there is a slight difference in the configuration dependent on
if the Nox T3 recorder or Nox A1 recorder is used (Refer to section

Intended Use
The Nox W7 LINK is a Medical Device Data System (MDDS) and allows for
electronic conversion and wireless transfer of medical device data between
an auxiliary medical device and a Nox recording device. The Nox W7 LINK
is connected to a serial port of an auxiliary medical device. Before the data
is transmitted over Bluetooth® link to the applicable Nox recording device
it is converted from serial to Bluetooth format.
Scope
This leaflet is designed to instruc
t users on how to use the Nox W7
LINK with supported auxiliary devices.
Warnings and Cautions
• Warning: Do not use damaged equipment, sensors or accessories.
This may result in bad performance of the Nox W7 LINK or patient/
operator injury.
• Warning: The
Nox W7 LINK
is not certified to be used for continuous
monitoring where failure to operate can cause injuries or death of the
patient.
• Warning: The RF function of the Nox W7 LINK might influence the
performance of other devices in close proximity and lead to potential
serious harm.
• Warning: Only use the medical grade power adapter provided by Nox
Medical as part of the Nox W7 LINK KIT package to power the Nox W7
LINK. The use of other power adapters may result in electric shock or
overheating of the power adapter/burns.
• Warning: Use of the Nox W7 LINK with auxiliary devices that have not
been validated by Nox Medical may result in electric shock. Always use
the Nox W7 LINK with validated auxiliary devices. Auxiliary devices need
to comply with applicable IEC 60601-1 safety standards for medical
electrical equipment.
• Warning: Do not use the Nox W7 LINK KITs in a Magne
ti
c Resonance
Imaging (MRI) environment. That might lead to serious patient harm.
Instructions for Us
e
1. Preparing a Study with the Nox W7 LINK
When configuring a No
x recording device for an ambulatory study with the
Nox W7 LINK in the Noxturnal software, the applicable Nox W7 LINK is
added by entering its Bluetooth address in the relevant field. Two different
addresses are used, depending on if the Nox A1 recorder is being used or
the Nox T3 recorder:
Nox A1 Recorder: The Nox W7 LINK’s Bluetooth address (BDA) is used and
has 12 digits. The BDA can be found on the Nox W7 LINK’s label.
Nox T3 Recorder: The Nox W7 LINK’s serial number (SN) is used and has 9
digits. The SN can be found on the Nox W7 LINK’s label.
2. Connecting to a Resmed S9™/AirSense™10 Device
The Nox W7 LINK is connected to the serial interface output located on
the Resmed Embletta Adapter. The Nox W7 LINK has thumbscrews which
can be used for more secure placement. For thumbscrews use a 4mm flat
screwdriver.
Note: The supported modes are AutoSet and CPAP.
3. Connecting to a Radiometer Device
The Nox W7 LINK KIT - R includes a DB9 male to male mini null modem.
Connect the null modem to the Nox W7 LINK, use thumbscrews for secure
placement. For thumbscrews use a 4mm flat screwdriver.
Connect the applicable serial port extension cable (available from
Radiometer) to the Radiometer device and connect the Nox W7 LINK
to the serial interface located on the extension cable.
4. Connecting to
a Nonin RespSense Device
The Nox W7 LINK KIT - R includes a DB9 male to male mini null modem.
Conne
ct the null modem to the Nox W7 LINK. Connect the Nox W7 Link
to the serial interface output located on the side of th
e Nonin RespSense.
Use the thumbscrews for secure placement. For thumbscrews use a
4mm flat screwdriver.
5. Connecting to SenTec Digital M
onitors
The Nox W7 LINK KIT - S includes a DB9 mal
e to male mini null modem.
The null modem is connected to the serial interface output located at the
back of the SenTec device. Connect the Nox W7 LINK to the null modem.
Use thumbscrews for more secure placement. For thumbscrews use a 4mm
flat screwdriver.
6. Starting a Study
a. Connect the Nox W7 LINK to the applicable auxiliary device as instructed
above (Step 2, 3, 4 or 5) and make sure the Nox Mini USB cable is
connected to the NOX W7 LINK and the Power Adapter (FW7721M/05).
b. Turn on the auxiliary device. The blue LED on the link starts blinking.
c. Turn on the Nox recording device.
d. The green LED on the NOX W7 LINK starts blinking, indicating Bluetooth
connection with the Nox recording device.
Note: Establishing Bluetooth connection may take up to 2 minutes.
e. Now a Bluetooth connection has been established between the Nox
recording device and the auxiliary device. The auxiliary device’s signals
are being recorded.
States of the Nox W7 LINK’s LEDs
The NOX W7 LINK is equipped with two LEDs. The green LED indi
cates the
status of the transmission. It blinks when the device is communicating with
the Nox recording device. It is steady when the device is on standby. The
blue LED indicates that the auxiliary device is streaming data to the device.
Maintenance
When the Nox W7 LINK is not in use, disconnect it from auxiliary
devices and store in a dry place.
