2 DXM Controller
2.1 DXM Hardware Configuration Overview
The DXM100-Bx Wireless Controller can have multiple configurations. The DXM100-Bx Wireless Controller will have a
model number label on the housing. Use the model number and model table above to identify which boards are included in
the controller.
When opening the DXM100-Bx Wireless Controller, follow proper ESD grounding procedures. Refer to the ESD warning in
the appendix.

The DXM100-Bx Wireless Controller I/O base board provides connections for all inputs, outputs and power. The base board
also contains a 12 V solar controller that accepts connections to a solar panel and SLA battery. The battery connection can
also be used with line power to provide a battery backup in case of line power outages.
The ISM radio, either a MultiHop or DX80 Gateway, fits on the base board in the parallel sockets. Install the ISM radio so
the U.FL antenna connection is to the side with the SMA antenna connectors. Connect the U.FL cable from the ISM radio
U.FL to the right side U.FL connector. The ISM radio boards are available with either a 900 MHz radio or a 2.4 GHz radio.
The SAM4 processor board plugs into the base board using the two 20 pin socket connectors. The board sits above the ISM
radio socket and held by the base board standoffs. Position the processor board so the USB and RJ45 Ethernet connection
is to the front, away from the SMA antenna connections.
The top plugin PCB is the optional cellular radio. This plugs into the SAM4 processor board with the U.FL antenna
connection to the left. Attach the antenna cable from the cellular module to the left U.FL connection on the base board.
The top housing contains the LCD display board. The display board is connected to the base board using a ribbon cable
with a 20 pin connector.
In some DXM models, the cellular radio module may be replaced with an ISM radio. The top ISM radio antenna connection
will be to the left SMA connector.
