The OE367-22 BACnet ® Link provides bi-directional translation of
data and information between BACnet ® devices and Orion VAV/CAV,
CW/HW and MUA II unit controllers.
Up to 16 total, Orion VAV/CAV, CH/HW, MUA II or any combination
of these controllers may be connected to each BACnet
® Link. Up to 4
BACnet ® Links can be used on a Orion Controls system allowing for
a maximum of 64 total controllers to be used.
Data Sharing
The BACnet ® Link interface provides the following data sharing capa-
bilities:
• Provides values from points on the Orion side of the
gateway to BACnet
® devices as if the values were
originating from BACnet ® objects.
• Allows BACnet ® devices to modify point values on the
Orion controller side of the BACnet ® Link by using
standard BACnet ® write services
Scheduling
• Ability to allow BACnet ® devices to send Schedule events
to the Orion controller side of the gateway by using
standard BACnet
® services
Hardware Specifications
Table 1 below contains the hardware specifications for the BACnet ®
Link interface.
