Connection of GSM and Wi-Fi
Antennas
Depending on a modification of AutoGRAPH controller, it can be supplied with following
antenna:
•
Flat GSM antenna with an adhesive coating for it to be stuck to the window. GSM antenna
is supplied with AutoGRAPH-GSM and AutoGRAPH-GSM+ controllers.
•
Whip GSM/Wi-Fi antenna with a magnetic base. The combined GSM/Wi-Fi antenna
intended to receive both GSM and Wi-Fi signals is supplied with AutoGRAPH-GSM+WiFi
controller.
•
Whip Wi-Fi antenna with a magnetic base. This antenna is supplied with AutoGRAPH-WiFi
controllers.
These antennas must be connected to the connector in the lower-left part of the controller.
The position of the antenna is critical to good performance of the GSM and Wi-Fi
communication; therefore it is highly recommended to plan the antenna’s position on a vehicle
before installation.
The antenna should be located in an open area, which shall ensure free GSM signal
transmission.
Before attaching the antenna with an adhesive coating, wipe the window surface with the
cloth supplied with the antenna. If the antenna is supplied without a cloth, clean the window
surface with any cloth damped with alcohol-based liquid before sticking the antenna.
When locating the antenna make allowance for the length of its cable. When laying the cable, avoid
sharp edges. Cable bend radius should be at least 10 cable diameters (about 3-5 cm).
Do not fix antenna before you make settings and configure your system, it is highly recommended to
determine its final position and install only when you are absolutely sure that the system is configured
and operates properly.
i
NOTE
Do not splice or cut the antenna cable.
In order to avoid cross-talk effects place the GSM and GPS/GLONASS antennas at least 50 cm away
from each other.
