1. WWAN Secondary Antenna Connector (WR41-U and WR41-C models): An SMA female
connector that connects the unit’s secondary cellular antenna. It is highly recommended to use
the secondary antenna for diversity. In most circumstances, dual antennas provide improved
signal strength and better performance.
2. Power connector: Connects the router to a power source. The power cord input can be AC, DC
and 4-pin Molex connectors. Secure the barrel plug connector by rotating it by 90 degrees once
installed into the Digi TransPort router. Center pin is positive.
3. Serial 0 Port: This RJ45 port provides an asynchronous RS232 serial port for connecting 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. See TransPort WR41 serial pinout for a pinout diagram.
4. Hardware Expansion Port: Various hardware upgrades are available for this unit and are
populated via this expansion port. See Additional hardware features below for further
information.
5. Case Ground: Connect an additional case ground if necessary.
6. WWAN Primary Antenna Connector: An SMA female connector that connects the unit’s
primary cellular antenna.
7. LAN Port: This RJ45 port connects the unit to a 10/100 base-T LAN. The port performs auto-
sensing for speed and wiring, and can handle a straight-through or cross-over cable.
