3 Components and Power Supply
In order to configure this, you need to connect the AUX port to an asynchronous terminal (or to a PC with terminal
emulation).
To use it as a configuration port for the router, please see section

3.7.3 Connecting to a WWAN Antenna (Cell connectors)
The OA5725A routers may have two or four connectors to connect the WWAN antennas, depending on the number
of WWAN modules incorporated in the device.
To assemble and dismantle the antennas, simply screw the antenna cable into the connectors labeled CELL1 and
CELL2, which are located on the front of the device.
Antenna installation is essential in the OA5725A routers in order to improve the quality of the signal received and
transmitted by the Wireless WAN module (GPRS, UMTS, HSDPA, HSUPA, HSPA+, LTE, etc.).
Note
- To achieve optimum performance, the router should always have the WWAN antennas installed.
- The device must have the corresponding software license installed to ensure the Wireless WAN inter-
face is operative.
There are some cellular telephony technologies that use the antenna diversity mechanism to improve the quality of
the received signal (HSUPA, HSPA+, LTE, CDMA EV-DO, etc.). Consequently, the OA5725A routers have two con-
nectors incorporated (ANT.1 and ANT.2) for each module installed in the device (CELL1 and CELL2).
• The MAIN antenna for each module (CELL1 and CELL2) is installed in the ANT.1 connector.
• The auxiliary or DIVERSITY antenna for each module (CELL1 and CELL2) is installed in the ANT.2 connector.
Module 1
ANT.1 CELL1 -> MAIN Antenna
ANT.2 CELL1 -> DIVERSITY Antenna
The following image shows you where to find the antenna connectors for the CELL1 module.
