Chapter 4: E2 Controller
A workgroup should ALWAYS start with controller address 1 and go up from there. DO NOT skip over controller addresses. The
list of suitable controller/display terminal address pairs is shown below:
Table 4-11. Corresponding Controller to Terminal pLAN Addresses.
Controller (I/O board) 1 2 3 4 5 6 7 8
Display Terminal 32 31 30 29 28 27 26 25
You must assign the terminal and controller I/O board addresses for each controller to be grouped. Review Sections 4.6.2.1 to
4.6.2.3 first, before turning power on and assigning addresses. Do not interconnect the controllers together before assigning their
terminal and I/O board pLAN addresses.
The first step is to change the terminal address of each controller to 0, referring to Section 4.6.2.1 below. You must set the
terminal address to 0 before you can assign the controller (I/O board) address.
NOTE: If the terminal remains inactive (no key is pressed) for more than 30 seconds, the group setup procedure is exited
automatically, without saving any changes.
4.6.2.1 Configure the Terminal Address
The address of the terminal (display) can only be configured if its telephone jack is connected to the I/O control module in the
electric box and power is turned on. The factory default value for the display terminal address is 32. To reassign the terminal
address, press and hold the (up-arrow ( ), down-arrow ( ) and Enter ( ) keys simultaneously for five seconds until the
Address Configuration screen shown below appears with the flashing cursor in the top left corner:
Figure 4-68. Terminal (Display) Address screen.
1. To change the address of the terminal (Display address setting), press the Enter key once. The cursor will move to the
address field (nn).
2. Use the up and down arrow keys to select the desired value (0), and confirm by pressing Enter again.
Figure 4-69. Display Address screen.
The Display Address Changed screen will appear, indicating the display address selected is not the same as the one saved
previously and the new value will be saved to the permanent memory.
3. Once the terminal address is set to zero, cycle the power to the unit Off and then back On.
NOTE: If the “Display address setting:__" field is set to 0, the terminal will communicate with the controller (I/O board) using
point-to-point protocol (not pLAN). The display field “I/O Board address:__” will disappear as it has no meaning until you
set the controller (I/O board) pLAN address.
