8. Enter the Priority IP Address One, which is the IP address that will have priority when communicating
with the CDDP-A.
9. Enter the Priority IP Address Two, which is the second IP address that will have priority when communi-
cating with the CDDP-A.
10. Enter the Idle Timeout value, in minutes. The Idle Timeout is the amount of time that elapses after a
connection has been lost and before the Modbus will close the connection, typically one minute.
11. Determine if you should enable White Listed IP Addresses. If this box is NOT checked, then all IP
address within the network will be able to connect to the CDDP-A. If this IS checked only the IP
addresses listed below will be able to connect to the CDDP-A. You can enter up to six IP addresses
that will be allowed to connect to the CDDP-A. If you wish to view a list of what devises are already
connected to the welder, press the Connected Devices button. If any device is connected to the welder
a light will appear next to the Connected Devices button. If not devices are connected the light will be

12. Once the above settings have been entered, press the Submit Modbus Settings button to submit and
save all settings. At this point the CDDPA is ready to connect and communicate through the Ethernet/
IP connection.
13. Plug the CDDPA Ethernet port into the network using a Cat5e/Cat6 cable.
Note: You can control the CDDP-A using many dierent software applications. In this documentation, instruc-

php. The diagnostic tool allows you to communicate with
the CDDP-A. While the diagnostic tool is for testing, and not
intended for a production environment, it is useful to show
communication between Modbus and the CDDP-A.
• The diagnostic tool will display the Conguration screen.
If not, choose Connection Setup from the File menu. See
