Appendix D (Building Interface) - Carrier ComfortLink 6 Series Controls, Start-Up, Operation, Service, And Troubleshooting

Building Interface —
The 30GXN,GXR,HX chiller can
be interfaced with multi-vendor control systems through 3 levels
of inter-operability using BacLink, DataPort™, or DataLINK™
devices. BacLink functions as a gateway between a CCN and a
BACnet system to facilitate the passing of data from the CCN to
BACnet. The Carrier DataPort is an interface device that allows
other HVAC control systems to "read only" values in system
elements connected to a CCN communication bus. The Carrier

DataLINK device is an interface device that allows other HVAC
control systems to read and change ("read/write") values in
system elements connected to a CCN bus. Both DataPort and
DataLINK devices request data from a specified CCN system
element and translate this data into ASCII characters off
network. Information from the 30GXN,GXR,HX chiller control
to support interface are listed in the following tables.
