Setup and adjustments

Important: 

Electrostatic discharge can damage controller components. Use proper

electrostatic discharge precautions during installation, setup, and servicing to avoid damaging

the controller.

Setting the device address

FX-PCV18 controllers are subordinate devices on N2 buses. Before operating field controllers on a

bus, you must set a valid and unique device address for each controller on the bus.
You set a field controller’s device address by setting the positions of the switches on the Device

Address DIP switch block at the top of the controller (Figure 3). Device addresses 1 through 253 are

the valid N2 addresses for these N2 controllers.

Note: 

The FX-PCV18 is an N2 controller, but it is also capable of being field-converted to

BACnet MS/TP. Valid MS/TP addresses for wired FX-PCV controllers are 4 through 127, and valid

addresses for wireless FX-PCV controllers are 132 through 255. We recommend you consider

using the BACnet MS/TP addressing scheme to simplify the BACnet MS/TP conversion process.

The DIP switch block (Figure 13) has eight switches numbered 128, 64, 32, 16, 8, 4, 2, and 1.

Switches 128 through 1 are device address switches.

Figure  13: Device address switches set to 21

To set the device addresses on an FX-PCV controller:

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 eight address switches (128 through 1) to ON, so that the sum of the

switch numbers set to ON equals the intended device address. 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 to ON, followed by Switch 1

(16+4+1=21). See Figure 13.

3.  Set a unique and sequential device address for each of the field controllers connected on the

N2 bus, starting with device address 1. To ensure the best bus performance (if the protocol is

changed to BACnet MS/TP), set sequential device addresses with no gaps in the device address

range (4, 5, 6, 7, 8, 9, and so on). The field controllers do not need to be physically connected

on the bus in their numerical device address order.

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

the controller’s cover.

Refer to the 

N2 Communications Bus Technical Bulletin (LIT-636018)

 for more information on field

controller device addresses and how to set them on N2 buses.
