Digi TransPort WR41
Two screws are on the bottom to mount the Digi TransPort WR41. These are the screws that hold the top of the
case to the bottom. These screws need to be removed and the holes can then be used for mounting. Digi also has
a bracket (Part number 76000775, same as the one for the Digi TransPort WR21 above) that fits over the WR41
and has ‘ears’ or tabs that make it easier to mount. Note that to install this bracket the four rubber ‘feet’ must be
removed. They are easily pried off with a flathead screw driver. Digi also has a SIM cover (Part number 76000787,
again the same as the Digi TransPort WR21) that prevents anyone from removing the SIM card.
Dimensions of the Digi TransPort WR41 are 120mm x 173mm x 32mm (LxWxH). Note that you should choose an
enclosure that allows enough room to connect the power connector, Ethernet cables (and/or the serial cable), and
the antennas (or SMA RF connector on a pigtail coax cable to a bulkhead connector if you are going to use antennas
external to the enclosure).
Power for the Digi TransPort WR41 can come from any 8-48V DC power supply capable of sourcing 1.5 amps. In
extreme high temperature environments you should choose a power supply that can source a higher current do to
the typical de-rating of most power supplies. There is only one connector type for the high temperature version of
the Digi TransPort WR41. It’s a 4 pin locking Molex connector. Digi has a high temperature power supply specific to
the Digi TransPort WR41 (part number 76000790).
