Possible Cause The PPDA does not allow JPDC and JPDS terminal boards to be mixed. The PPDA has detected both
JPDC and JPDS terminal boards connected through ribbon cables to the PDM.
Solution
• Verify that there are only JPDC or JPDS boards present, but not both.
• Verify that the ToolboxST configuration matches the hardware configuration.
• Reboot the PPDA after the hardware connections are corrected.
