“Wi-fi” mode
–
connection using external module "Arnavi Wi-Fi".
Allows you to connect to a server (or two servers) via Wi-fi access point. This mode has priority over
data transmission via GSM channel. If an access point is available, data transmission will be carried out
primarily via Wi-Fi. The Arnavi Wi-Fi module supports 802.11 b/g/n Wi-Fi protocols.
IF THE DEVICE USES WIFI CONNECTION, IT IS IMPOSSIBLE TO UPLOAD THE
TACHOGRAPH .DDD FILE, UPLOAD PHOTOS AND TRANSFER DATA USING EGTS
PROTOCOL
Connection:
Wi-Fi module has RS-232 interface and ‘EN’ input. If ‘EN’ is shorted to ground – module is activated.
"EN" output can be rigidly closed to the ground, or can be connected to free arnavi 5 outputs (U0, U1, U2,
U3). The last connection method allows the tracker to independently control the operation of the external
module, as well as to reboot it in emergency situations.
The connection diagram using the U0 output is shown in the figure:
