You need to set the sub module address via DIP before installation.
Steps:
1. Remove the rubber cover on the sub module rear panel to expose the DIP switch.
2. Set the sub module address according to the DIP rules, and re-install the rubber cover
Important:
- DIP 1, 2, 3, 4 are used to code the sub module address; DIP 5, 6, 7, 8 are not used.
- Valid sub module address range is 1 to 8.
- The No. should be unique for sub modules that are connected to the same main unit.
