This manual describes the installation, configuration and use of the OPTCJ BACnet fieldbus 
adapter from Eaton’s electrical business. The OPTCJ is a plug-in board that is compatible 
with any open or enclosed drive product that uses an SVX or SPX processor module 
(including the HVX9000 or CPX9000 family). The OPTCJ adapter can be used in slots D or E of 
the processor module. 
BACnet is an acronym for “

etwork”. BACnet is a true non-
proprietary communication protocol conceived by a consortium of building management 
and system users. BACnet has been adopted by ASHRAE (American Society of Heating 
Refrigeration and Air-conditioning Engineers) as its standard network protocol, and is rapidly 
gaining international acceptance. BACnet is used in building automation, lightning control, 
air-conditioning and in heating automation. The protocol is suitable for enterprise wide 
communication in large building automation projects.
The OPTCJ BACnet adapter is an MS/TP (Master-Slave/Token-Passing) device that supports 
RS-485 physical layer.
WARNING
 
Internal components and circuit boards are at high potential when
the drive is connected to the power source. This voltage is
extremely dangerous and may cause death or severe injury if you
come into contact with it.
