2.1 Attaching the SOM to the Common Processor
Board
Remove mounting screws (4) from
Common Processor board (sold separately). The screws are shipped installed in
jack-screws. If existing SOM module is already mounted, use Allen wrench
(supplied with SOM) to eject SOM module by inserting the wrench into each
jack-screw and turning counter-clockwise at each location until SOM module is
loose.
Before installing new SOM, make
sure all jack-screws are tight by inserting the wrench and turning clockwise at
each location.
Install the SOM module on the
Common Processor Board. Ensure it is oriented such that all connectors are
aligned. Press firmly on the edges to ensure the connectors mate (may have to
apply significant pressure).
Install mounting screws (4x) in
each corner of the SOM (see below). Tighten each screw to ensure all connectors
are fully mated. Don’t over-tighten.
Insert
the supplied Linux SD card into the Micro SD card slot (see below). The location
of the card slot is on the backside of the Common Processor Board.
Connect the supplied USB cable to
the USB/Serial Debug connector as shown. Connect other end to PC. Launch a
terminal program (example, TeraTerm) and connect to first of four UARTs that are
assigned to USB port. Set terminal to operate at Baud 115200, 8b no parity, and
flow control off.
If a
DisplayPort panel is available (not included), connect the supplied DisplayPort
cable to the EVM as shown. Connect other end to DisplayPort panel. If no panel
is available, this step can be skipped.
Confirm the boot configuration
switches SW8 and SW9 are set as shown.
Connect a +12 VDC power supply
(not included) with minimum output rating of 5 Amp, positive inner and negative
outer terminals, female barrel 5.5 mm x 2.5 mm. Recommended power supply is CUI
Inc. SDI65-12-U-P6 or equivalent.
To turn EVM system on, set switch
SW2 to the ‘ON’ position. To turn EVM off, set switch SW2 to ‘OFF’.
