Issue
Trying to add B3 controllers to BCX and they are not coming online.
Product Line
Andover Continuum
Environment
- BCX 4040
- Continuum 1.9X
- B3XXX controllers
Cause
BacNet wiring can not be in a star configuration. There can not be more than two terminating 120 Ohm resistors.
Resolution
- The Bus must be wired in series with end line 120 Ohm resistors.
- Install a B-Link if the bus path cannot be wired in series.
Please see the BacNet Technical Reference manual for wiring examples.
