About this task

ZEC controllers are master devices on BACnet® MS/TP sensor or zone buses. Before operating field controllers on a bus, you must set a valid and unique device address for each controller on the bus.

To set a field controller’s device address, change the positions of the switches on the device address DIP switch block, at the top of the controller. Device addresses 4 through 127 are the valid addresses for the ZEC and BYP controllers.

Note: The ZEC and BYP controllers ship with all address switches set to ON. Set a valid and unique device address on the field controller before applying power to the controller on the bus.

The DIP switch block has eight switches numbered 128, 64, 32, 16, 8, 4, 2, and 1.

To set the device addresses on a field controller, follow these steps:

Procedure

  1. Set all of the switches on the field controller’s device address DIP switch block (128 through 1) to OFF.
  2. Set one or more of the six address switches (32 through 1) to ON, so that the sum of the switch numbers set to ON equals the intended device address.
  3. Set the highest number switch that is less than or equal to the intended device address to ON. Then continue setting lower numbered switches until the total equals the intended address. For example, if the intended device address is 21, set Switch 16 to ON first, then set Switch 4 ON, followed by Switch 1 (16+4+1=21).
  4. Set a unique and sequential device address for each of the field controllers connected on the System Bus or Zone Bus, starting with device address 4.

    To ensure the best bus performance, set sequential device addresses with no gaps in the device address range (4, 5, 6, 7, and so on). The field controllers do not need to be physically connected on the bus in their numerical device address order.

  5. Write each field controller’s device address on the white label below the DIP switch block on the controller’s cover.
