and IP connection
DIP Switch shown :Not
Terminated
Push both white switches down to
enable BACnet, Lonworks, or
Modbus termination.
There are pin headers located on the control (‘U’ shaped) that
the Protocessor bridge module plugs in directly. Align the
sockets on the Protocessor with the pin headers on the
control, then press into place. All power for the bridge is
supplied by the version 2.x control. Communication from the
Protocessor bridge to the H-Net control is also handled
through the sockets.
Next, connect the BACnet or LonWorks network cable to the
Protocessor module or configure the bridge using the
software tools. Once connected use the DIP switch to enable
termination.
NOTE: Do not plug the Protocessor
module in with power on or
Protocessor module may be damaged.
Additional Bulletins and Instructions for Configuring BACnet or LonWorks are available on the website.
