In pLAN network, both the dap4 controller and the display have separate addresses. “Display Ad-
dress” is he address of the display and I/O Board Address is the address of the dap4 controller.
In a Zone Master network where all units are connected via pLAN, each unit and its display must
have different addresses. Below is the recommendation addresses combination:
Table 1: Recommended Addresses in Zone Master control
Unit 1 Unit 2 Unit 3 Unit 4 Unit 5 Unit 6 Unit 7 Unit 8
dap4 pLAN address 12345678
Display Address 32 31 30 29 28 27 26 25
Unit 9 Unit 10 Unit 11 Unit 12 Unit 13 Unit 14 Unit 15 Unit 16
dap4 pLAN address 9 10 11 12 13 14 15 16
Display Address 24 23 22 21 20 19 18 17
2.0.3 Changing the address of the dap4 controller:
Since all units will be shipped as Unit #1, a change of Controller Addresses needs to be done in
order to establish a Zone Master communication.
Follow this procedure to set pLAN address to each dap4 controller in the zone:
• Press button A for 5 seconds by using a small screw driver or a small pin. The pLAN ad-
dress will start fl ashing.
• Press repeatedly or hold the button until reaching the required address (2, 3, 4…16).
Note: You can set up dap4 address from 1 - 16. Address 17 to 32 are reserved for display mod-
ules. Follow the table on previous page to set the display module address.
• Wait until the address starts fl ashing rapidly. In this stage the address has been saved but it
not yet active for the application program. Power down the controller.
• Power up the controller again. The address is now set to the dap4
