WIRING
All power, input and output (I/O) wiring must be in accordance
with Class I, Division 2 wiring methods and in accordance with
the authority having jurisdiction.
CONNECTING TO EARTH GROUND
Each DA50D has a chassis ground terminal on the top of the
unit. Your unit should be connected to earth ground. Steps should
be taken beyond connecting to earth ground to eliminate the
buildup of electrostatic charges.
The chassis ground is not connected to signal common of the
unit. Maintaining isolation between earth ground and signal
common is not required to operate your unit. But, other equipment
connected to this unit may require isolation between signal
common and earth ground. To maintain isolation between signal
common and earth ground care must be taken when connections
are made to the unit. For example, a power supply with isolation
between its signal common and earth ground must be used. Also,
plugging in a USB cable may connect signal common and earth
ground.

FACTORY RESET BUTTON
The factory reset button located in the lower left area of the
front of the unit can be used to access the system console. Refer
to software manual for access procedure and available options.
CONFIGURING A DA50D
The DA50D is configured using Crimson® 3.1 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
DA50D using the latest Crimson version, you are assured that
your unit has the most up to date feature set. Crimson software
can configure the DA50D through the Serial programming port,
USB device port, Ethernet ports or microSD card.
The microSD card can be used to program a DA50D by placing
an image file on the SD card. The card is then inserted into the
target DA50D and powered. Refer to the Crimson 3.1 User
Manual for more information on the proper names and locations
of this file.
DA50D Cellular Connectivity
Cellular connectivity is achieved using the DA 4G LTE - CAT4
Modem Sled. Refer to the documentation shipped with your DA
4G LTE - CAT4 Modem Sled for installation and setup information.
Ethernet Communications
Ethernet communications can be established at either 10
BASE-T or 100 BASE-TX. The DA50D’s RJ45 jack is 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 3.1 User
Manual and Red Lion’s website for additional information on
Ethernet communications.

RS232 PORT
The DA50D0B has
one RS232 serial port
that can be used for
either programming or
for communications. The
RS232 port can be used
for either master or slave
protocols. The serial port
has a pair of LEDs to
indicate transmit and
receive activity. The
pinout is shown to the
right.
CAUTION: Only UL listed wiring with temperature
ratings greater than 90 °C permitted for Class I, Division
2, Zone 2 and ATEX/IECex installations.
ATTENTION: Seul le câblage homologué UL avec des
températures nominales supérieures à 90°C est autorisé
pour les installations de classe I, Division 2 , zone 2 et
ATEX/IECex.
