XML Config File
The configuration software configures the DXM by creating an XML file that is transferred to the DXM using a USB or
Ethernet connection. The DXM 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 operation.
The wireless network devices are a separate configurable system. Use the DX80 User Configuration Software to configure
the internal DX80 wireless Gateway and the attached wireless Nodes. Use the MultiHop Configuration Software if the internal
radio is a MultiHop device.
All tools can be connected to the DXM using a USB cable or an Ethernet connection.
1.4 DXM100-Sx Hardware Configuration Overview
The DXM100 can have multiple configurations. The DXM100 will have a model number label on the housing. Use the model
number and model table in the datasheet to identify which boards are included in the controller.
When opening the DXM100, follow proper ESD grounding procedures.
Important:
•Electrostatic discharge (ESD) sensitive device
• ESD can damage the device. Damage from inappropriate handling is not covered by warranty.
• Use proper handling procedures to prevent ESD damage. Proper handling procedures include
leaving devices in their anti-static packaging until ready for use; wearing anti-static wrist straps; and
assembling units on a grounded, static-dissipative surface.

2.1.1 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.
2.1.2 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.
2.1.3 Disable Serial
Disable an unused local serial connection to reduce the power consumption of a data radio powered from the solar assembly
or from batteries. All radio communications remain operational.
2.1.4 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. For battery-powered devices, increasing the throughput decreases battery life.
Important: Prior to date code 15341 and radio firmware version 3.6, the frame timing was 40 ms (OFF) or
20 ms (ON).

2.2 Binding the ISM Radio of a Modbus Slave
A DXM100 (for example, model DXM1x0-S*R2) contains two boards: a MultiHop ISM radio and an I/O base board. Each
board is a separate Modbus device and requires a unique Modbus ID.
• The ISM radio is not required to have a Modbus ID because there are no registers to manage, but it generally does
have a Modbus ID assigned to it.
• The I/O board must have a Modbus ID to access the I/O register data and configuration data.
To bind the DXM100 (as either a repeater or slave radio) to its master radio, follow the MultiHop binding instructions. If the
binding instructions are not included in the master radio datasheet, refer to the MultiHop Quick Start Guide (p/n 152653) or
Instruction Manual (p/n 151317).
The ISM radio board's Modbus ID is assigned from the master radio during binding using the master radio's rotary dials or
the DXM Controller's LCD Binding menu. For example, if the master's binding number is 25, the DXM Slave ISM radio's
Modbus ID is set to 25.
By default, the I/O board's Modbus ID is set to 11. To change the Modbus ID, use the I/O board DIP switches. For
applications requiring Modbus IDs outside the range of the DIP switches, write a Modbus ID to a Modbus register on the I/O
board. (See Setting the Modbus Slave ID on the I/O Base Board.)
Use the MultiHop Configuration Software to display and configure a MultiHop radio network. With the DXM100, only the ISM
radio displays on the Network View screen. The Modbus ID of the I/O board is a separate device that is not a part of the radio
network. Although the I/O board does not show up in the Network View, it is accessible when using the Register View
functions.

By default, current (0–20 mA) is selected using jumpers 1 and 2 and registers 4008 and 4028 contain
a value of 2.
To select voltage (0–10 V) for output Aout1, set jumper 1 in the voltage position (V) and set Modbus
register 4008 on the I/O board (SID 200) to 3.
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.
3.1.3 Setting the Modbus Slave ID on the I/O Base Board
Only DXM100-S1 and -S1R2 Slave models require that the Modbus Slave ID to be adjusted on the I/O base board. The
DXM100-Sx Modbus Slave models use DIP switches J and K to set the Modbus Slave ID. This device can use a Modbus
register 6804 in the I/O board to access the full range of Modbus Slave IDs.
On the DXM100-Sx Modbus Slave models, use the DIP switches at location K to define the lower digit of the Modbus Slave
ID.
DIP Switch location J defines the course group of Modbus Slave IDs. DIP Switch 4 must be set to ON for DXM100-S1,
DXM100-S2, DXM100-S1R2, and DXM100-S2R2 models.

3.2 Applying Power to the DXM100-Sx Modbus Slave
Apply power to the DXM100-Sx Modbus Slave using either 12 to 30 V DC or a 12 V DC solar panel and 12 V sealed lead
acid battery.
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-Sx Modbus Slave
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.
3.2.1 Connecting a Battery
When attaching a battery to the DXM100 as a backup battery or as a solar battery, verify the charging algorithm is set
properly. The factory default setting for the battery charging algorithm assumes you are using 12 to 30 V DC to recharge the
battery.
The charging algorithm is designed to work with a sealed lead acid (SLA) battery only.
• When using 12 to 30 V DC, connect the 12 to 30 V DC + to pin 2 and connect the ground to pin 3.
• When using main dc power with a back up battery (default configuration), connect the incoming main power pin 2 (+)
and to pin 3 (-). Connect the 12 V sealed lead acid battery to pin 4 (+) and pin 5 (-). The incoming main power must
be 15 to 30 V dc to charge the battery.
3.2.2 Supplying Power from a Solar Panel
To power the DXM100-Sx Modbus Slave from a 12 V dc solar panel, connect the solar panel to power pins 2(+) and 3(-).
Connect a 12 V dc sealed lead acid (SLA) rechargeable battery to pins 4(+) and 5(-).
The factory default setting for the battery charging configuration assumes you are using 12 to 30 V DC power to recharge the
battery. If the incoming power is from a solar panel, you must change the charging configuration.
The battery charging configuration defaults to a battery backup configuration. To change the charging configuration from the
menu system:
1. From the DXM100 LCD menu, navigate to System Config > I/O Board > Charger.
2. Select Solar for solar panel configurations or DC for battery backup configurations.
To change the charging configuration by writing to Modbus register 6071 on the I/O base board (Slave ID 11):
1. Write a 0 to select the solar power charging configuration.
3.3 Connecting the Communication Pins
The base board communications connection for external Modbus device uses the primary RS-485.
RS-485. The primary RS-485 bus is a common bus shared with the ISM radio board (Modbus Slave ID 1).
RS-232. The RS-232 bus is not currently defined.

The I/O base board is a Modbus slave device that communicates using Modbus commands. Refer to the Modbus Registers
section for more descriptions of each Modbus register on the DXM100-Sx Modbus Slave.
3.4.1 Universal Inputs
The universal inputs on the DXM100-Sx Modbus Slave can be programmed to accept several different types of inputs:
• Discrete NPN/PNP
• 0 to 20 mA analog
• 0 to 10 V analog
• 10k temperature thermistor
• Potentiometer sense
• Bridge
• NPN raw fast
Any input can be used as a synchronous counter by configuring the input as a discrete NPN/PNP input.
Use the DXM Configuration Software tool to write to the appropriate Modbus registers in the I/O board to configure the input
type. The universal inputs are treated as analog inputs. When the universal inputs are defined as mA, V, or temperature, use
Modbus registers to configure the operational characteristics of the inputs. These parameters are temperature conversion
type, enable full scale, threshold and hysteresis. Refer to the DXM100 Controller Instruction Manual (p/n 190037) for the
parameter definitions.
When a universal input is configured as an NPN or PNP input type, it can be enabled to be a synchronous counter. Enable
the counter function by setting Modbus register 'Enable Rising' or 'Enable Falling' to 1. See Modbus I/O Registers for the
DXM100-S1x I/O Base Board on page 24 for universal input register definitions.
Pin Universal Input Modbus Register Description
27 4 4 Program the universal inputs to accept input types NPN, PNP, 10k thermistor, 0 to 10 V, 0 to 20 mA,
or potentiometer. The default setting is 8: NPN raw fast. To set the input type, write the following
values to the Input Type Modbus registers defined in Modbus I/O Registers for the DXM100-S1x I/O
Base Board on page 24.
0 = NPN
1 = PNP
2 = 0 to 20 mA
3 = 0 to 10 V DC
4 = 10k Thermistor
5 = Not used
6 = Not used
7 = Bridge
8 = NPN Raw Fast (default)
28 3 3
31 2 2
32 1 1
Thermistor Input
A thermistor input must use a 10k temperature thermistor between ground and the universal input. The thermistor
must be a 10k NTC (Banner model number BWA-THERMISTOR-002) or equivalent. Select the temperature
conversion of degrees C (default) or degrees F by writing Modbus registers defined in Modbus I/O Registers for the
DXM100-S1x I/O Base Board on page 24.
Potentiometer Input
A potentiometer input is created from three inputs: a voltage source (pin 30) that supplies 5 V to the potentiometer
and two inputs set to voltage inputs to read the voltage across the potentiometer. See the DXM tech note for setting
up a potentiometer.
Bridge Input
The bridge input is not implemented yet.
NPN vs NPN Raw Fast
The difference between NPN and NPN Raw Fast is the amount of settling time given to the input. Switch the input
type to NPN if the input is not detecting a transition.

Synchronous Counters
When an input is configured as a counter (inputs set to NPN/PNP), the input counts the input signal transitions. The
count value is stored into two 16-bit Modbus registers for a total count of 32-bits (unsigned). To program an input to
capture the edge transition counts, follow Example: Configure Input 1 as a Synchronous Counter on page 14.
Synchronous counter sample the inputs every 10 ms. The input logic does not detect rising or falling edges, but
instead samples the input every 10 ms to find level changes. The input signals must be high or low for more than 10
ms or the input will not detect transitions. Because most signals are not perfect, a realistic limit for the synchronous
counter would be 30 to 40 Hz.
Example: Configure Input 1 as a Synchronous Counter
1. Change the Source Register selection to I/O Board Registers.
2. In the Write Registers area, write Modbus register 4908 to 1 to enable counting on the rising edge of the input
signal.
3. Read Modbus registers 4910 and 4911 to get the 32-bit value of the count.
Example: Change Universal Input 2 to a 0 to 10 V dc Input
1. Write a 3 to Modbus register 3326 on Modbus Slave ID 11 (I/O board).
2. Cycle power to the device.
3. Using the Register View tab, read register 3326 to verify it is set to 3.
Example: Change Analog Output 1 to a 0 to 10 V dc Output
1. Change the Source Register selection to I/O Board Registers.
2. Set jumper 1 on the I/O base board to the 0 to 10 V position. Refer to the base board image for the analog output
jumper position.
3. Write a 3 to Modbus register 4008 on Modbus Slave ID 11 (I/O board).
4. Cycle power to the device.
5. Using the Register View tab, read register 4008 to verify it is set to 3.

4.1.2 Setting the Modbus Slave ID on the I/O Base Board
Only DXM100-S1 and -S1R2 Slave models require that the Modbus Slave ID to be adjusted on the I/O base board. The
DXM100-Sx Modbus Slave models use DIP switches J and K to set the Modbus Slave ID. This device can use a Modbus
register 6804 in the I/O board to access the full range of Modbus Slave IDs.
On the DXM100-Sx Modbus Slave models, use the DIP switches at location K to define the lower digit of the Modbus Slave
ID.
DIP Switch location J defines the course group of Modbus Slave IDs. DIP Switch 4 must be set to ON for DXM100-S1,
DXM100-S2, DXM100-S1R2, and DXM100-S2R2 models.

DXM100-Sx Modbus Slave Example—To set the DXM100-Sx Modbus Slave to a Modbus Slave ID of 34, set the following:
Location J DIP switches set to 1=OFF, 2=ON
Location K DIP switches set to 1=OFF, 2=OFF, 3=ON, 4=OFF
The location J DIP switches set the upper Modbus Slave ID digit to 3 while the location K DIP switches set the lower digit to
4.
Setting the DXM I/O Board Modbus Slave ID using Modbus Registers—Write to the I/O board's Modbus register 6804 to
set the Modbus Slave ID to any valid Modbus Slave ID (1 through 245).
• For the DXM100-Sx Modbus Slave model, all switches on DIP switch K should be in the OFF position to use the
Modbus register slave ID.
4.2 Applying Power to the DXM100-Sx Modbus Slave

4.2.1 Connecting a Battery
When attaching a battery to the DXM100 as a backup battery or as a solar battery, verify the charging algorithm is set
properly. The factory default setting for the battery charging algorithm assumes you are using 12 to 30 V DC to recharge the
battery.
The charging algorithm is designed to work with a sealed lead acid (SLA) battery only.
• When using 12 to 30 V DC, connect the 12 to 30 V DC + to pin 2 and connect the ground to pin 3.
• When using main dc power with a back up battery (default configuration), connect the incoming main power pin 2 (+)
and to pin 3 (-). Connect the 12 V sealed lead acid battery to pin 4 (+) and pin 5 (-). The incoming main power must
be 15 to 30 V dc to charge the battery.
4.2.2 Supplying Power from a Solar Panel
To power the DXM100-Sx Modbus Slave from a 12 V dc solar panel, connect the solar panel to power pins 2(+) and 3(-).
Connect a 12 V dc sealed lead acid (SLA) rechargeable battery to pins 4(+) and 5(-).
The factory default setting for the battery charging configuration assumes you are using 12 to 30 V DC power to recharge the
battery. If the incoming power is from a solar panel, you must change the charging configuration.
The battery charging configuration defaults to a battery backup configuration. To change the charging configuration from the
menu system:
1. From the DXM100 LCD menu, navigate to System Config > I/O Board > Charger.
2. Select Solar for solar panel configurations or DC for battery backup configurations.
To change the charging configuration by writing to Modbus register 6071 on the I/O base board (Slave ID 11):
1. Write a 0 to select the solar power charging configuration.
4.3 Connecting the Communication Pins
The base board communications connection for external Modbus device uses the primary RS-485.
RS-485. The primary RS-485 bus is a common bus shared with the ISM radio board (Modbus Slave ID 1).
RS-232. The RS-232 bus is not currently defined.
