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.

The DXM Configuration Software allows the user to adjust parameters that govern the operation of the DC latch outputs.
Most applications will not require any changes for correct operation. Software parameters include:
•
Enable H-Bridge
—Enable or disable the H-bridge output. Default Enabled.
•
Voltage
—The voltage applied to the output when the output is activated. Default 13 V dc.
•
Cap Warmup Time
—The amount of time given to charge the output capacitor. The more time given to charge the
output capacitor the more energy will be available to turn on the output. Default 80 ms
•
Switch Time
—The amount of time the output is turned on to be able to change the solenoid output. Default 40 ms
