Communication-Link Wire
BMTW-SVN01F-EN 63
Figure 30. Comm5 Daisy Chain Repeater Connection
* A continuous shield is required when shielded
wire is used. If unshielded communication wire is
used, no shield connections are necessary. At each
controller, splice shield wire and tape back to
prevent grounding. Connect shield wire to earth
ground at BCU and repeater.
**The value of the termination resistor is
dependent on the wire type: 105 Ω for 22 AWG,
Level 4 wire and 82 Ω for 18 AWG, Trane
“purple” wire.
