4. Select a COMM port from the drop-down list and click Connect.
5. Click on the Register View tab on the left part of the page.
6. Change the Source Register selection to I/O Board Registers.
7. In the Write Registers area, write Modbus register 4908 to 1 to enable counting on the rising edge of the input signal.
8. 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. Connect the DXM Controller to the PC.
2. Launch the DXM Configuration Tool software.
3. Connect to the DXM Controller by selecting the Device > Connection Settings menu option. You may connect using
either USB or Ethernet.
4. Select a COMM port from the drop-down list and click Connect.
5. Click on the Register View tab on the left part of the page.
6. Change the Source Register selection to I/O Board Registers.
7. Write a 3 to Modbus register 3326 on Modbus Slave ID 200 (I/O board).
8. Cycle power to the device.
9. 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. Connect the DXM Controller to the PC.
2. Launch the DXM Configuration Tool software.
3. Connect to the DXM Controller by selecting the Device > Connection Settings menu option. You may connect using
either USB or Ethernet.
4. Select a COMM port from the drop-down list and click Connect.
5. Click on the Register View tab on the left part of the page.
6. Change the Source Register selection to I/O Board Registers.
7. 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.
8. Write a 3 to Modbus register 4008 on Modbus Slave ID 200 (I/O board).
9. Cycle power to the device.
10. Using the Register View tab, read register 4008 to verify it is set to 3.
