Wi-Fi antenna.
2.2 Rear Panel Features
1. Secondary Cellular (WWAN) Antenna Connector (WR41-U and WR41-C models) - This SMA female
connector is used to connect the unit’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.
2. Power Cord Input - This socket is used to connect the unit to a power source.
Note: The power supply has a twist-lock connector which can be secured by rotating it 90 degrees once
installed into the TransPort unit.
3. SERIAL 0 Port - This RJ45 port provides an asynchronous RS232 serial port which may be used to
connect the unit 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. A pinout diagram is available in Appendix A: SERIAL 0 Port
Pin-out Diagram on page 23.
4. Hardware Expansion Port - Various hardware upgrades are available for this unit and are populated via
this expansion port. See the Additional Hardware Features section on page 10 for further information.
5. Case Ground - This connector is used to connect an additional case ground if necessary.
6. Primary Cellular (WWAN) Antenna Connector - This SMA female connector is used to connect the unit’s
primary cellular antenna.
7. LAN Port - This RJ45 port is used to connect the unit to a 10/100 base-T LAN. The port is auto-sensing for
speed and wiring (straight-through or cross-over).
