connector. Tighten screws on control connector.
c. When using Biphase, and the dome is in a star
configuration (or is the last dome on a daisy chain), it
requires a 110
Ω
terminating resistor (included) across
pin 8 (C+) and pin 9 (C–).
Daisy chain configuration is not possible if fiber optic
accessory is used.
