1. Primary cellular (WWAN) antenna connector: An SMA female connector that connects the
router’s primary cellular antenna.
2. Secondary Wi-Fi (WLAN) Antenna connector (Wi-Fi models only): An SMA male connector
that connects the router’s secondary Wi-Fi antenna.
3. Secondary cellular (WWAN) antenna connector (WR44-U and WR44-C models): An SMA
female connector that connects the router’s secondary cellular antenna. It is highly
recommended to use the secondary antenna for diversity. In most circumstances, dual
antennas will provide improved signal strength thus better performance.
4. Primary Wi-Fi (WLAN) antenna connector (Wi-Fi models only): An SMA male connector that
connects the router’s primary Wi-Fi antenna.
5. Power connector: Connects the router to a power source. The power supply has a twist-lock
connector which can be secured by rotating it 90 degrees once installed into the TransPort
router. Center pin is positive.
6. 11-58VDC (Aux): Connects the router to an alternative 11-58VDC power supply (not supplied)
using a fused power cable which can be purchased separately. This cable also contains two
programmable IO signal lines, one is an input signal, and the other is an input/output signal.
7. SERIAL 0 port: This DB9 port provides an asynchronous RS232 serial port for connecting the
router to a compatible serial device. This is a DCE serial port and allows CLI access to the
device by default; the baud rate is 115200.
8. Hardware expansion port: Various hardware upgrades are available for this router and are
populated via this expansion port. See TransPort WR44 additional hardware features for more
information.
