CONFIGURING A DA70A
The DA70A can be configured using Crimson
®
3.2 software.
Crimson is available as a no charge download from Red Lion’s
website. Crimson updates for new features and drivers are posted
on the website as they become available. By configuring the
DA70A using the latest Crimson version, you are assured that
your unit has the most up to date feature set. Crimson software
can configure the DA70A through the Serial programming port,
USB device port, Ethernet ports or microSD card.
The microSD card can be used to program a DA70A by placing
an image file on the microSD card. The card is then inserted into
the target DA70A and powered. Refer to the Crimson 3.2 User
Manual for more information on the proper names and locations
of this file.

DA70A Cellular Connectivity
Cellular connectivity is achieved using the DA 4G LTE - CAT4/
CAT1 Modem Sled. It is recommended that the Cellular Sled be
installed into sled slot 1, the topmost sled slot in the carriage of
the Gateway. Refer to the documentation shipped with your DA
4G LTE - CAT4/CAT1 Sled.
Ethernet Communications
Ethernet communications can be established at either 10Base
T or 100Base TX. The DA70A’s RJ45 jacks are wired as a NIC
(Network Interface Card). For example, when wiring to a hub or
switch use a straight-through cable, but when connecting to
another NIC use a crossover cable. Refer to the Crimson 3.2
Software Guide and Red Lion’s website for additional information
on Ethernet communications.
