3.1.2 I/O Board Jumpers for the B1 and S1 Models
Hardware jumpers on the DXM I/O board allow the user to select alternative pin operations. Turn the power off to the device
before changing jumper positions.

Analog output characteristics for
AO2 (pin 19) and AO1 (pin 20)
Defines current (0–20 mA) or voltage (0–10 V) for analog output 1 and 2.
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.

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.
1 Must be in the ON position for the -S1 and -S1R2 model)
2 Uses value in Modbus register 6804.
