the antenna counter-clockwise.
2. Place the Remote antenna where the signal reception
is good.
3. Safely route the Remote antenna wire terminal nut to
the Smart IO.
4. Remove the terminal blocks on either side of the SMA
Connector for easier access to the connector.

7. Remount the terminal blocks.
NOTE: Ferrite ring is not required when the Remote
Antenna is used with the Smart IO.
REMOTE ANTENNA PLACEMENT
• Place and align the antenna in a way that the Wi-Fi
signal does not interfere with many obstacles.
• Obstacles such as metal, steel-reinforced concrete wall
filter ~10-90% of the Wi-Fi signal. Other obstacles such
as drywall, wood, glass filter ~0-10% of the Wi-Fi signal.
• The antenna has a strong signal transmission/reception
from the side. See figure below. Position the sides of the
antenna towards the device it is communicating with
(e.g Gateway/WiFi Node).
• Keep the antenna away from devices that cause wireless
interference such as other Wi-Fi network and
telecommunications equipment.

Wall/Panel
1. Remove the Terminal covers if applicable.
2. Disconnect all the communication and power supply
terminals from the Smart IO.
3. If the remote antenna is installed, remove the termi-
nal blocks on either side of the SMA Connector for
