Illustration 9—Ethernet Network Connection ("E" Models)
Connect (Optional) MS/TP Network
CAUTION
To avoid damage from ground loops
and other communication issues in
networked MS/TP model FlexStats,
correct phasing on MS/TP network
and power connections on ALL the
networked controllers is critically
important!
NOTE:
See the
for additional wiring
considerations.
1. For the non-E models (only), connect the BAC-
net network to the
BACnet MS/TP terminals
using shielded twisted-pair cable.
NOTE:
Use 18 or 22 gauge AWG shielded
twisted pair cable with maximum
capacitance of 51 picofarads per foot
(0.3 meters) for all network wiring. Log
Recommendations Technical Bulletin
for recommendations. For principles
and good practices when connecting
BACnet Networks (Application Note
A. Connect the
–A
terminals in parallel with
all other
–A
terminals on the network:
B. Connect the
+B
terminals in parallel with all
other
+B
terminals on the network.
C. Connect the
shields
of the cable together
at each device using a wire nut (or the
S
terminal in other KMC BACnet controllers).
CAUTION
When re
installing the cover on
the backplate, be careful not to
damage or dislodge any wiring or
components. Do not use excessive
force. If there is any binding, pull
off the cover and examine pins and
terminal socket connectors.

1. For BAC-19xxxxC
E
models (only), plug an
Eth-
ernet patch cable
into the back of the FlexStat.
NOTE:
The Ethernet patch cable should be
T568B Category 5 or better and a
maximum of 328 feet (100 meters)
between devices.
