E.4.1 NOTE ABOUT WI-FI
Control Pack network
The SSID (identification) of your Control Pack is its serial number (for instance “CP3P-2824-FA”).
The WLAN provided by the Control Pack is an “Access-Point” Wi-Fi network, complying with 802.11 a/b/g/n
bands.
Customized setup - Authorized channels
The Control Packs (CP2 and CP3) are delivered with a default Wi-Fi setup.
For robustness and versatility, the Control Pack can operate on two different wireless frequency bands, the
2.4 GHz band or the 5 GHz band. Depending on your work environment and application, you can choose
the best frequency band.
Each frequency band is subdivided into channels (frequency ranges). The CP offers channels 1 through 11
for the 2.4 GHz band and channel 36 for the 5 GHz band. The CP is set to channel 8 by default.
• Longer range
• Penetrates walls and floors
• Use indoors and outdoors
• Slower speed
• More susceptible to interference
from other wireless sources
• Faster speed
• Less susceptible to interference
from other wireless sources
• Shorter range
• Cannot penetrate solid objects
• Use indoors only
Before you change your CP to the 5GHz frequency band, check your local regulations. Some countries
forbid the 5 GHz band and others limit the 5 GHz band to indoor-only.
In EU, 5 GHz channels are limited to 36-48. The Wi-Fi chipset must be changed accordingly
with RDS Toolbox.
For Wi-Fi setup, please read the RDS User manual.
The people in charge of the setup of the Control Pack must ensure that the specified band
and channel is authorized in his country.
Hexagon Manufacturing intelligence is not responsible of a wrong use of the Wi-Fi
channels.
The Wi-Fi of the computer may be managed by specific software for the device. In this case,
refer to its manual to connect to the ABSOLUTE ARM network and setup the IP address.
If the Wi-Fi of the computer manages preferred order for networks, make sure that “CP{x}-
{xxxx}-{xx}” network is at the top of the list.
Ex: if Windows
®
manages the Wi-Fi, in the wireless configuration, select “change the order of
preferred networks”, select then the Control Pack Network and click on “Move up” until it
becomes at the top of the list.
