1.2 DXM Automation Protocols
The DXM Controller supports the following automation protocols.
Modbus RTU. The DXM Controller manages two separate physical ports running the Modbus RTU protocol. The DXM
Controller is the Modbus Master when operating the Modbus master RTU port. The DXM Controller uses the master Modbus
RTU bus to communicate with locally connected Modbus devices or uses the Banner wireless radio to communicate with
remote Modbus devices. The other Modbus RTU port is used by a host system to access the DXM Controller as a slave
device. The slave Modbus RTU port allows access all the internal registers concurrently with the master RTU port. By
default, the Modbus RTU ports are active. Configure the port parameters using the DXM Configuration Tool.
Modbus TCP/IP. A host system acting as a Modbus client can access the DXM Controller using the Modbus TCP/IP
protocol over Ethernet. Standard Modbus port 502 is used by the DXM Controller for all Modbus TCP/IP requests. All
internal registers are available to the host system concurrently with Modbus RTU. By default, Modbus TCP/IP is active.
EtherNet/IP™. The Ethernet port is actively running EtherNet/IP. From the factory the DXM Controller is configured to
read and write registers on DX80 wireless devices 1 through 16. Custom configurations can be set using the DXM
Configuration Tool. By default, EtherNet/IP is active.
1.3 DXM Modbus Overview
The DXM Controller uses internal 32-bit registers to store information. The processor's internal Local Registers serve as the
main global pool of registers and are used as the common data exchange mechanism. External Modbus device registers
can be read into the Local Registers or written from the local data registers.
The DXM Controller, as a Modbus master device or slave device, exchanges data using the Local Registers. Modbus over
Ethernet (Modbus/TCP) uses the Local Registers as the accessible register data.
Using Action, Read/Write, and Threshold Rules allows you to manipulate the processor's Local Registers. The ScriptBasic
programming capabilities extends the use of Local Registers with variables to create a flexible programming solution for
more complex applications.
The processor's Local Registers are divided into three different types: integer, floating point, and non-volatile. When using
Local Registers internally, the user can store 32-bit numbers. Using Local Registers with external Modbus devices follows
the Modbus standard of a 16-bit holding register. Local Registers are accessible as Modbus ID 199.
Accessing the I/O Base and the LCD follows the same communication as an external Modbus device. Each device has an ID
number to uniquely identify itself. The I/O base is Modbus ID 200 and the LCD is Modbus ID 201.

1.4 DXM Configuration Tool Overview
The DXM Configuration Tool configures the DXM Controller by creating
an XML file that is transferred to the DXM Controller using a USB or
Ethernet connection. The DXM Controller can also receive the XML
configuration file from a Web server using a cellular or Ethernet
connection.
This configuration file governs all aspects of the DXM Controller
operation. The wireless network devices are a separate configurable
system. Use the DX80 User Configuration Tool (UCT) to configure the
internal DX80 wireless Gateway and the attached wireless Nodes. Use
the MultiHop Configuration Tool (MCT) if the internal radio is a
MultiHop device.
All tools can be connected to the DXM Controller using a USB cable or
an Ethernet connection.

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.

Application Mode
The MultiHop radio operates in either Modbus mode or transparent mode. Use the internal DIP switches to select the mode
of operation. All MultiHop radios within a wireless network must be in the same mode.
Modbus mode uses the Modbus protocol for routing packets. In Modbus mode, a routing table is stored in each parent
device to optimize the radio traffic. This allows for point to point communication in a multiple data radio network and
acknowledgement/retry of radio packets. To access a radio's I/O, the radios must be running in Modbus mode.
In transparent application mode, all incoming packets are stored, then broadcast to all connected data radios. The data
communication is packet based and not specific to any protocol. The application layer is responsible for data integrity. For
one to one data radios it is possible to enable broadcast acknowledgement of the data packets to provide better
throughput. In transparent mode, there is no access to the radio's I/O.
Baud Rate and Parity
The baud rate (bits per second) is the data transmission rate between the device and whatever it is physically wired to.
Set the parity to match the parity of the device you are wired to.
Disable Serial
If the local serial connection is not needed, disable it to reduce the power consumption of a data radio powered from the
solar assembly or from batteries. All radio communications remain operational.
Transmit Power Levels/Frame Size
The 900 MHz data radios can be operated at 1 watt (30 dBm) or 0.250 watt (24 dBm). For most models, the default
transmit power is 1 watt.
For 2.4 GHz radios, the transmit power is fixed at 0.065 watt (18 dBm) and DIP switch 5 is used to set the frame timing.
The default position (OFF) sets the frame timing to 60 milliseconds. To increase throughput, set the frame timing to 40
milliseconds. Note that increasing the throughput decreases the battery life.
Prior to date code 15341 and radio firmware version 3.6, the frame timing was 40 ms (OFF) or 20 ms (ON).
3.1.2 DIP Switch Settings for the Gateway PEx Board Modules
Transmit Power—The 900 MHz radios transmit at 1 Watt (30 dBm) or 250 mW (24 dBm). While the Performance radios
operate in 1 Watt mode, they cannot communicate with the older 150 mW radios. To communicate with 150 mW radios,
operate this radio in 250 mW mode. For 2.4 GHz models, this DIP switch is disabled. The transmit power for 2.4 GHz is
fixed at about 65 mW EIRP (18 dBm), making the 2.4 GHz Performance models automatically compatible with older 2.4
GHz models.

3.2 Binding and Conducting a Site Survey with the ISM Radio
The DXM Controller can have an internal MultiHop master radio or DX80 Gateway radio (star architecture) installed. Before
the ISM radio can communicate with DX80 Nodes, the DXM Controller must be bound to the other radios in the wireless
network. Use the DXM Controller LCD menu to bind radios to the internal DXM radio.
The LCD display and the processor applications share the external Modbus connection. If the processor is configured to
constantly interact with Modbus, it may cause issues with the LCD display attempting to use the functions of the ISM radio.
To alleviate the contention:
• Load a DXM configuration file that slows down the read/write rules.
• Disable the DXM configuration file from loading into the processor by setting DIP switch 4 to ON (on the processor
board). Reboot the device. When the processor starts back up, it will not load the configuration file and remains
idle. See the DXM100 Controller Instructional Manual (190037) for the processor DIP switch location.
3.2.1 Entering Binding Mode
Under the ISM Radio menu, use the down arrow button to highlight the Binding menu. Click ENTER.
The ISM Radio menu is slightly different for the two different types of internal radio. The ISM Type displays 'MultiHop'
when the MultiHop radio board is installed and 'DX' when the DX80 star architecture radio board is installed.
Use the up/down arrows to enter the device number to bind to. When binding to devices with rotary dials, the device
number has no effect. To bind to devices without rotary dials, the device number is saved as the device Modbus slave ID in
the MultiHop network or the Node number in a DX80 network.
After entering binding mode on the DXM Controller, put the end device into binding mode to execute the binding process.
Most end devices enter binding by triple-clicking button 2 on the device. For specific instructions on entering binding for a
specific device, refer to the individual datasheet for that device.
To bind more devices, click the back button, change the device number (if needed), then enter binding again.
3.2.2 Conducting a Site Survey
Although the MultiHop and DX80 devices are architecturally different, the site survey process is similar when conducted
from the DXM LCD menu. From the ISM Radio menu, use the down arrow to highlight the Site Survey menu. Click
ENTER.
Use the Up or Down arrows to select the Node number (DX80 network) or Modbus Slave ID (MultiHop network). Click
ENTER to run the site survey with that Node or slave.
For a DX80 network, the Gateway controls the site survey and the results display on the LCD. Running Site Survey on a
DX80 network does not affect the throughput of the DX80 network.
For a MulitHop network, the master device passes the site survey request to the intended Modbus slave device. The Site
Survey runs and the results display on the LCD. Running Site Survey on a MultiHop network stops all network traffic to
that device.
3.3 Modbus Registers for the Gateway Performance 1 Watt Radio
The DX80 Gateway (PE5) is a star-based architecture device that contains all the Modbus registers for the wireless
network within the Gateway. To access any input or output values within the entire wireless network, read the appropriate
Modbus register from Gateway.
There are 16 Modbus registers allocated for each device in the wireless network. The first 16 registers (1–16) are allocated
for the Gateway, the next 16 (17–32) are allocated for Node 1, the next 16 (33–48) are allocated for Node 2 and so forth.
There are no inputs or outputs on the DXM embedded Gateway but the Modbus registers are still allocated for them.
Although only seven Nodes are listed in the table, the Modbus register numbering continues for as many Nodes as are in
the network. For example, the register number for Node 10, I/O point 15 , is 175. Calculate the Modbus register number
for each device using the equation:
Register Number = I/O# + (Node# × 16)

3.3.1 Alternative Modbus Register Organization
The Sure Cross DX80 Alternative Modbus Register Organization registers are used for reordering data registers to allow
host systems to efficiently access all inputs or outputs using a single Modbus command. The register groups include the
input/output registers, bit-packed registers, and analog registers. This feature is only available with the Performance
models using version 3 or newer of the LCD firmware code.

Refer to your device's datasheet for a list of the active inputs and outputs. Not all inputs or outputs listed in this table may
be active for your system.
Discrete Bit-Packed Registers
Discrete bit-packed registers include the discrete status registers, discrete inputs, and discrete outputs.
Bit packing involves using a single register, or range of contiguous registers, to represent I/O values.
When networks use similar Nodes to gather data using the same I/O registers for each Node, discrete data from multiple
Nodes can be bit packed into a single register on the Gateway. The bit-packed data is arranged by I/O point starting at
Modbus register 6601. For example, Discrete IN 1 for all the Nodes in the network is stored in three contiguous 16-bit
registers.
The most efficient way to read (or write) discrete data from a SureCross®DX80 Gateway is by using these bit-packed
registers because users can read or write registers for all devices using one Modbus message. The following registers
contain discrete bit-packed I/O values for the Gateway and all Nodes. Values are stored first for the Gateway, then for
each Node in order of Node address.

6671-6673 Input 7 from all devices 6751–6753 Output 7 from all devices
6681-6683 Input 8 from all devices
Status registers (6601-6603) contain a bit-packed representation defining the devices that are operational in the
wireless system.
Input registers from all devices use Modbus registers 6611 through 6683 to organize the least significant bit into a
sequential array of registers. The first register contains the least significant bit from the input values for the Gateway
through Node 15. The second register contains the input values for Node 16 through Node 31, and the third register
contains the input values for Nodes 32 through 47.
For discrete inputs, only the least significant bit is used. For analog inputs, the least significant bit indicates if the analog
value is above or below the selected threshold value (when using the threshold parameter). For example, a least
significant bit of one (1) indicates the analog value is above the selected threshold value. A least significant bit of zero (0)
indicates the analog value is below the threshold value.

Output registers from all devices use Modbus registers 6691 through 6753 to organize the least significant bit into a
sequential array of registers. Output 8 (I/O point 16) cannot be written using the discrete format.
Analog 16-Bit Registers (Registers 6801 through 9098)
The most efficient way to read (or write) analog data from a Gateway is by using these 16-bit analog registers. Most
networks consist of similar Nodes reporting data using the same I/O registers for each Node. For this reason, the analog
data is arranged by I/O point using Modbus registers 6801 through 9098. For example, Input 1 for Gateway and all Nodes
is stored in the first 48 contiguous blocks of 16-bit analog registers, beginning with register 6801.
In this format, users can read a 16-bit holding register for all devices or write to a register for all devices using one
Modbus message. Using these registers is the most efficient way to read all status registers, read all analog inputs, or
write all analog outputs.
The following registers contain analog I/O values for the Gateway and all Nodes. Values are stored first for the Gateway,
then for each Node in order of Node address.
Inputs Outputs
Modbus Register Address
(Decimal) Description (Inputs) Modbus Register Address (Decimal) Description (Outputs)
6801 Input 1 for Gateway 8001 Output 1 for Gateway
6802 Input 1 for Node 1 8002 Output 1 for Node 1
6803 Input 1 for Node 2 8003 Output 1 for Node 2
... ... ... ...
6951 Input 2 for Gateway 8151 Output 2 for Gateway
6952 Input 2 for Node 1 8152 Output 2 for Node 1
6953 Input 2 for Node 2 8153 Output 2 for Node 2
... ... ... ...
7101 Input 3 for Gateway 8301 Output 3 for Gateway
7102 Input 3 for Node 1 8302 Output 3 for Node 1
7103 Input 3 for Node 2 8303 Output 3 for Node 2
... ... ... ...
7851 Input 8 (Status Register) for Gateway 9051 Output 8 for Gateway
7852 Input 8 (Status Register) for Node 1 9052 Output 8 for Node 1
7853 Input 8 (Status Register) for Node 2 9053 Output 8 for Node 2
... ... ... ...
For example, 6801 contains the input 1 value for the Gateway, 6802 contains the input 1 value for Node 1, and 6848
contains the input 1 value for Node 47.
3.4 Modbus Registers for the MultiHop 1 Watt Radio Board
The DX80 MultiHop master radio (HE5) is a tree-based architecture device that allows for repeater radios to extend the
wireless network. Each device in a MultiHop network is a Modbus device with a unique Modbus ID. Modbus registers in a
MultiHop network are contained within each individual radio device. To get Modbus register data from a MultiHop device,
configure the DXM Controller to access each device across the wireless network as an individual Modbus slave device.
Example: MultiHop Modbus Register Table

Cellular Radio Connection. Install the cellular modem onto the SAM4 board with the cellular modem's U.FL connector on
the left. The antenna cable will go between the cellular U.FL connector and the left I/O board U.FL connector. Only install/
remove a cellular modem when the power to the device is disconnected.
Force Cloud Push button. Press and hold this button for two seconds to send an immediate push message from the
device (if properly configured).
Clear Password. By default, the DXM Controller does not require a password to load a configuration file. If a password is
defined, the DXM Controller requires that you enter the password before uploading a configuration file. To change the
password, you must already know the current password. If you do not know the current password, clear the password
from the DXM Controller.
CAUTION: Clearing the password erases the current configuration and any program files, log files, or history files
currently on the DXM Controller.
Follow these steps to clear the password requirement from your DXM Controller.
1. Turn off the power.
2. Set DIP switch 4 to the ON position.
3. Press and hold button 'B'.
4. Apply power to the device.
5. After leaving the device powered on for a few seconds, turn off the power again.
6. Set DIP switch 4 to the OFF position.
7. Reload the configuration file before resuming normal operation.
The password is cleared from the system.

Set to ON to disable the LCD. This DIP switched should be ON when the LCD display board is not connected. The
factory default position is OFF.
4.1.2 Button Operation
The SAM4 processor button has two functions:
• Clearing the access password as explained above.
• Pressing the button for 5 seconds forces a Push to the webserver. This assumes a proper configuration for the
webserver.
4.1.3 LED Operation
By default, the four LEDs indicate the following conditions:
• LED 1 - Heartbeat, indicates the processor is running.
• LED 2 - Indicates the cellular modem power cutoff is active. If the incoming power is less than 11.2 V, the cellular
modem is powered down.
• LED 3 - XML configuration file was rejected.
• LED 4 - ScriptBasic program failed to load.
4.2 Ethernet
Before applying power to the DXM100-Bx Wireless Controller, verify the Ethernet cable is connected. If the Ethernet cable
is not connected when the device powers up, the DXM100-Bx Wireless Controller will not recognize the connection.
The Ethernet connection supports the DXM Configuration Tool, Modbus/TCP, and EtherNet/IP. ScriptBasic also has access
to Ethernet for custom programming. Use the DXM Configuration Tool to configure the characteristics of the Ethernet
connection, fixed IP addresses, DHCP, etc. The LCD menu allows the user to change the IP Address.
4.3 USB
The USB port is used with the DXM Configuration Tool to program the DXM100-Bx Wireless Controller. The USB port is also
used as the console output for the processor and ScriptBasic.
4.4 Modbus Registers - Internal Local Registers (Modbus Slave 199)
The main storage elements for the DXM Controller are its Local Registers, which can store 4-byte values that result from
register mapping, action rules, or ScriptBasic commands.
• Local Registers 1 through 850 are standard 32-bit signed registers.
• Local Registers 851 through 900 are non-volatile registers that are limited to 100,000 write cycles.
• Local Registers 1001 through 1900 are floating point format numbers. Each register address stores half of a
floating point number. For example, registers 1001 and 1002 store the first full 32-bit floating point number.
• Local Registers 10001 through 19000 are system, read-only, registers that track DXM Controller data and
statistics.
4.4.1 Local Registers 1–850 (Internal Processor Memory, 32-bit, Unsigned)
The local registers are the main global pool of registers. Local registers are used as basic storage registers and as the
common data exchange mechanism.
Modbus slave ID 0 is reserved for the processor.
DXM100-Bx Wireless Controller Instruction Manual
16 www.bannerengineering.com - Tel: [phone]

External Modbus device registers can be read into the local registers or written from the local registers. The DXM
Controller, as a Modbus master device or a Modbus slave device, exchanges data using the local registers.
Modbus over Ethernet (Modbus/TCP) uses the local registers as the accessible register data.
4.4.2 Local Registers 851–900 (Data Flash, Non-volatile, 32-bit, Unsigned)
The top 50 local registers are special non-volatile registers. The registers can store constants or calibration type data that
must be maintained when power is turned off.
This register data is stored in a data flash component that has a limited write capability of 100,000 cycles, so these
registers should not be used as common memory registers that change frequently.
4.4.3 Local Registers 1001–1900 (32-bit IEEE Floating Point)
These local registers are paired together to store a 32-bit IEEE floating point format number in big endian format.
Registers 1001 [31:16], 1002 [15:0] store the first floating point value; registers 1003, 1004 store the second floating
point number. There are a total of 500 floating point values; they are addressed as two 16-bit pieces to accommodate the
Modbus protocol.
Use these registers when reading/writing external devices that require Modbus registers in floating point format. Since
Modbus transactions are 16-bits, the protocol requires two registers to form a 32-bit floating point number.
4.4.4 Virtual Registers
The DXM Controller has a small pool of virtual registers that show internal variables of the main processor. Some register
values will be dependent upon the configuration settings of the DXM Controller.
Do not use Read Rules to move Virtual Local Registers data into Local Registers. Use the Action Rule > Register Copy
function to move Virtual Local Registers into Local Registers space (1-850).

To select voltage (0–10 V) for output Aout2, set jumper 2 in the voltage position (V) and set
Modbus register 4028 on the I/O board (SID 200) to 3.
5.2 Applying Power to the DXM100-Bx Wireless Controller
Apply power to the DXM100-Bx Wireless Controller using either 12 to 30 V dc or a 12 V dc solar panel and 12 V sealed
lead acid battery operating together.
The DXM100 has three power input and three power output options:
• Input Power:
◦12 to 30 V dc
◦12 to 30 V dc solar panel
◦12 V dc sealed lead acid battery with automatic charging
• Courtesy Output Power Supplies:
◦One 5 V dc fixed
◦Two 5 V dc or 16 V dc (DXM100-B1 models) or Two 5 V to 24 V dc (DXM100-B2 models)
The DXM Controller continuously monitors the health of the power inputs. If a power input fault is detected, the DXM
Controller automatically switches over to battery with continuous uninterrupted operation.
If the incoming voltage drops below 11.2 V dc, the cellular modem does not turn on and will not turn on until the voltage is
above 11.8 V dc. A text file (CmVMon.txt) on the internal micro SD card saves the periodic sampling of the incoming
voltage. If cellular operation stops because of voltage, it is logged in this file.
Pin Description
Pin 1 No connection
Pin 2 12 to 30 V dc input (+) or solar panel connection (+)
Pins 3, 5, 8, 17, 26, 29 Main logic ground for the DXM100-Bx Wireless Controller
Pin 4 Solar or backup battery positive input. Battery voltage must be less than 15 V dc. Use only a sealed lead acid (SLA)
battery.
5.2.1 Using Courtesy Power or Switch Power
Pin 18 of the DXM100-Bx Wireless Controller is a constant power source that supplies 5 volts up to 500 mA.
Pins 21 (switch power 2) and 30 (switch power 1) are switched power outputs. Configure the switched power outputs using
Modbus registers. The output voltage can be selected and is controlled using a Modbus register on the I/O board (Modbus
slave ID 200). The voltage options are:
• 5 volts or 16 volts for DXM100-B1 models; or
• 5 to 24 V dc for DXM100-B2 models.
Turn the switched power on or off using the output register 505 for switch power 1 or 506 for switch power 2. For
continuous power, set the Default Output register to 1, then cycle the power.
