2. Address Configuration: Each Modbus device on a single network must have a unique address. Set the switch block to assign
a unique address before the device is connected to the Modbus RS-485 network. If an address is selected that conflicts with
another device, neither device will be able to communicate.
3. The E34 uses two logical addresses. Panel 1 uses the base address as set on the DIP switches. Panel 2 uses this base address +
1. Address the E34 as any whole number between and including 1-246. Each unit is equipped with a set of 8 DIP switches for
addressing. See the diagram below.

1 2 4 8
4. To determine an address, simply add the values of any switch that is on.
For example:
LSB
Switch number 4 has an ON Value of 8 and switch number 6 has an ON Value of 32. (8 + 32 = 40). Therefore, the address for
Panel 1 is 40, and the address for Panel 2 is 41.
See the Address Selection section for a pictorial listing of the switch positions for Modbus address selection.
