621-3560 Honeywell Power module Brand new

Matched terminating resistors are required at each end of
a segment bus wired across (+) and (-). Use matched
precision resistors rated 1/4W ±1% / 80 - 130 Ohms.
Ideally, the value of the terminating resistors should
match the rated characteristic impedance of the installed
cable. For example, if the installed MS/TP cable has a a
listed characteristic impedance of 120 Ohm, install 120
Ohm matched precision resistors.
NOTE: The controller does not provide any network biasing.
Shield Terminating
Following proper MS/TP cabling shield grounding
procedures is important to minimize the risk of
communication problems and equipment damage caused
by capacitive coupling. Capacitive coupling is caused by
placing MS/TP cabling close to lines carrying higher
voltage. The shield should be grounded on only one end of
the MS/TP segment (typically the router end). Tie the
shield through using the SHLD (terminal 4) on the Spyder
BACnet Controller.
Sylk

Bus
Sylk is a two wire, polarity insensitive bus that provides
both 18 VDC power and communications between a Sylkenabled sensor and a Sylk-enabled controller. Using Sylkenabled sensors saves I/O on the controller and is faster
and cheaper to install since only two wires are needed and
the bus is polarity insensitive. Sylk sensors are configured
using the latest release of the Spyder Tool for WEBPro and
WEBStation.
