The D4412 and D6412 use SDI addresses 150 and 151 to communicate with the DX3010 Octo-Output Expander.
Up to two DX3010 Octo-Output Expanders may be used for adding Programmable Outputs (PO) to the control panel. PO 5-12 are added with a DX3010 addressed as 150, PO 13-20 are added with a DX3010 addressed as 151. Troubleshoot the error based on the following:
-
Not using DX3010 Octo-Output Expanders and dislaying: Missing SDI 150: Verify programming for PO 5-12 are set to (0,0)
-
Not using DX3010 Octo-Output Expanders and dislaying: Missing SDI 151: Verify programming for PO 13-20 are set to (0,0)
-
Using a DX3010 and dislaying: Missing SDI 150 or SDI 151: Verify correct wiring of the data wires from the panel to the DX3010. Inspect for opens or shorts.
