OPERATING INSTRUCTIONS
BACNET CONTROLLER- EVAP
The BACnet Controller is a native BACnet®, fully programmable, direct digital controller. It provides a
communication link between a BAS (Building Automation System) and the Cambridge unit. The
controller provides precise monitoring and control of connected points.
BACnet®MS/TP compliant operating at up to 76.8 kilobaud
BTL-certified controller
Standard input points for fan status, cooling status, discharge temperature, zone temperature, and
outdoor temperature
Standard output points for fan control, cooling control and fill and drain valves
Selectable operating modes (fan off/on/auto, cooling off/on/auto, heating off/on/auto)
Removable screw terminal blocks
Onboard USB port for firmware upgrades
Local user interface display for commissioning and monitoring

MS/TP NETWORK CONNECTION
Use stranded 3-wire twisted pair,
shielded cable to connect to FC BUS
(blue) terminals.
Run all low-voltage wiring and cables
separate from high-voltage wiring.
Connect the – terminals in parallel with
all other – terminals and the + terminals
in parallel with all other + terminals.
The FC bus Shield (SHD) terminal is
isolated and can be used to as a shield
drain connection.
END-OF-LINE TERMINATION
If a controller is on either end of a BACnet
MS/TP network an EOL terminator (JCI # MS-
BACEOL-0) must be installed for proper
network operation.

NETWORK PARAMETERS
Before operating controllers on a bus, you must
set a valid and unique device address for each
controller on the bus through the local display or
MAP gateway. Device addresses 4 through 127
are the valid addresses for these controllers. The
MAC address is set for a default of 4.
The baud rate is set for a default of Auto. The
controller will listen for the bus supervisor to
communicate first; then automatically set its
baud rate to the bus supervisor’s baud rate. If
you anticipate critical peer-to-peer
communication and therefore do not want the
controllers to wait for the bus supervisor to
establish the baud rate, you can specify the baud
rate for each device immediately at startup.
To change any of the network settings (Device
Name, Description, Address, Device Object ID)
go to Controller > Network from the local
display or MAP gateway.
NOTE: When changing any network parameters
it is recommended that the controller be
disconnected from the network while the
changes are being made and that the power be
cycled to the controller after all changes have
been made before reconnecting the controller to
the network.
