TransPort® WR44v2 Installation Guide
Page 15
The TransPort WR44 also allows for dual network installations where one wireless service can be used as a
back-up in the event that the primary service fails. These installations cannot be used to access two networks
simultaneously. By default, SIM 1 is used for access to the primary network and SIM 2 is used for the back-up
network.
For added security, Digi offers a “SIM Slot Cover Plate” that can be installed on the unit to deter theft or
tampering of the SIM cards, (see the Accessories section on page 23 for more information).
Step 2) Connect the Cellular (WWAN) Antenna(s):
Connect the cellular antenna to the “WWAN PRIMARY”
connector (SMA Female) on the unit. If the unit is equipped with a secondary cellular antenna connector
(WWAN SECONDARY), it is highly recommended to connect an additional antenna to this connector for
diversification. Dual antennas will provide improved signal strength thus better performance.
Note:
For most applications, the antenna(s) included with the unit will provide suitable reception, but some
circumstances/environments may require a higher quality antenna or one mounted in a different location. If
this is the case, Digi has many antenna options to chose from -- please contact us or visit www.digi.com. If
antennas other than the supplied antenna(s) are used, the separation between the two should be no less than
five inches (5”).
Step 3) (Wi-Fi models only) – Connect the Wi-Fi Antennas:
Connect the Wi-Fi antennas to the ‘WIFI
PRIMARY and WIFI SECONDARY’ antenna connectors (SMA Male).
Step 4) Connect the LAN Cable:
Connect one end of the Ethernet cable to the “LAN” port on the unit and the
other end to a LAN port on a PC.
Step 5) Connect the Serial Cable (optional):
Connect one end of the serial cable (not included) to the
“SERIAL 0” port on the unit and other end to the serial port on a third-party serial terminal device. If you wish
to connect the unit to a PC, it is recommended that you purchase Digi’s serial cable (P/N: 76000858).
Some TransPort models also include additional serial ports which have RJ45 connectors. For those models,
Digi offers the following serial cables for connectivity:
• P/N: 76000855 -- RJ45 to DB9 Female - 6’
• P/N: 76000856 -- RJ45 to DB25 Male - 6’
• P/N: 76000857 -- RJ45 to DB25 Female - 6’
Step 6) Connect the Power Supply:
Depending on model, the unit will either come with an AC power sup ply,
4-pin DC power cord, or a Fleet power cord. Instructions for all options are described below.
AC Power Supply
- Connect the locking barrel end of the power supply to the “MAIN” connector on the
unit, and plug the other end into a wall outlet. “International” units come with interchangeable Power Supply
Adapters which can be used according to regional needs.
4-Pin DC Power Cord
- Connect the 4-pin molded end of the cord to the “AUX” connector on the unit, and wire
the four bare wires accordingly to your needs. The red and black wires provide basic DC power input, and the
blue and green wires are programmable signal lines.
WARNING:
Only one of the power connectors should be used. Never apply power to both the MAIN and AUX
ports at the same time.
Fleet Power Cord
- Connect the 4-pin molded connector to the “Pwr” port on the unit. Connect the locking
barrel jack to the “MAIN” connector on the unit. Finally, wire the two bare wires accordingly to your needs.
For sample wiring diagrams and pinout information, see the 4-Pin DC Power Cord and Fleet I/O Interface User‘s
Guides, which can be found online at

Step 7)
When the unit is powered-up, the POWER indicator will illuminate and the unit will initiate a series of
diagnostic self-tests. During this process one or more of the other indicators will flash to show that the unit is
busy. When the flashing stops, the unit has completed its self-test diagnostics and is ready to be configured.
