CAUTION:
Possible equipment damage if miswired.
CAUTION:
Exceeding the power output (maximum 50W) of the 2-Series
integrated dual bus control system can result in system shutdown or a blown fuse.
NOTE:
Do not power up system until all wiring is verified. Care should be taken to
ensure date (Y,Z) and power (24,G) connections are not crossed. Data "Y" was data
"+". Data "Z" was data"-".
NOTE:
The cable consists of 1-#18 AWG twisted pair, tinned copper 1-#22 AWG
twisted pair with shield, tinned copper. There are six twists per foot per pair. The
jacket is teal color and labeled "CRESNET" every two feet. Liberty Wire carries the
cable (reference: CRESNET) and it is available in plenum or non-plenum versions.
NOTE:
Each 2-Series integrated dual bus control system has one 4-pin network
connector. Use the following Crestron products to interconnect to other devices
within a network (some permit network testing):
- CNTBLOCK, Network Terminal Block
- CNHBLOCK, Multi-Type Network Distribution Block
- CNXHUB, Cresnet Hub/Repeater
- ST-CNB, SmarTouch/Cresnet Terminal Expander
When calculating the wire gauge for a particular network run, the length of the run
and the power factor of each network unit to be connected must be taken into
consideration. If network units are to be daisy-chained on the run, the power factor
of each network unit to be daisy-chained must be added together to determine the
power factor of the entire chain. The length of the run in feet and the power factor of
the run should be used in the following resistance equation to calculate the value on
the right side of the equation.
