MS/TP Network Wiring Principles
Use the following principles when connecting a controller to an MS/TP
network:
• Use 18 gauge, twisted-pair, shielded cable with capacitance of no
more than about 50 picofarads per foot for all network wiring.
Belden cable model #82760 meets KMC requirements.
• Connect the –A terminal in parallel with all other –A terminals. Con-
nect the +B terminal in parallel with all other +B terminals.
• Connect the shields of the cable together at each controller. For KMC
BACnet controllers other than the FlexStat, use the S terminal. For
the FlexStat, use a wire nut.
• Connect the shield to an earth ground at one end only.
• To maintain communications in case of an open conductor on the
network cable, redundant wiring routed separately enhances reli-
ability.
• Connect no more than 128 addressable BACnet master devices (total)
to one MS/TP network. The devices can be any mix of controllers or
routers. (Up to 127 slave devices can also be connected.)
• Limiting the MS/TP network size to no more than about 60 BAC-
A1616BC, BAC-5800, BAC-7000, and FlexStat series controllers will
optimize network performance.
• Use a KMC KMD-5575 repeater after every 31 MS/TP devices or if
the cable length exceeds 4,000 feet (1,220 meters). Generally, use no
more than four repeaters per MS/TP network. Do not connect the
cable shield to the circuit GND terminal on the KMD-5575. For each
network segment, connect the shields to a good earth ground at only
one end of the segment; tape back the shield ground at the other end.
• Place a KMC KMD-5567 surge suppressor in the cable where it exits
a building.

tional information about installing controllers.
