CSAT3B Three-Dimensional Sonic Anemometer For an application that requires SDM communications from multiple CSAT3Bs in series, or with a daisy-chain topology, first connect to each CSAT3B as described in Section 7.1, Settings, to ensure each sensor has been assigned a unique SDM address. Connect a CSAT3BCBL1 to the Power/SDM port of the terminal CSAT3B. The opposite end will have an M16 connector that mates with one of the split M16 connectors on the Power/SDM splitters (pn 30293). Next, screw the side of the splitter with only one M16 connector to the Power/SDM port of the second CSAT3B. Connect another CSAT3BCBL1 to the splitter and down to the next CSAT3B. Continue the daisy-chain until the last CSAT3B. The final CSAT3BCBL1 should have pigtail wire ends to connect to the SDM and 12 V ports of a datalogger. If several CSAT3Bs using SDM communications are being connected in parallel or with a star topology, connect a CSAT3BCBL1 cable to the Power/SDM port of each CSAT3B, and connect the other wire leads on the pigtail end of the cables to a HUB-SDM8 bus (see Section 5.2.4.3, HUBSDM8). Connect the wires so that all wires of a common color or signal are on the same rail. Then, use a CABLE5CBL with pigtail wire leads to connect the HUB-SDM to the SDM and 12 V ports of a datalogger. 34

CSAT3B Three-Dimensional Sonic Anemometer
For an application that requires SDM communications from multiple
CSAT3Bs in series, or with a daisy-chain topology, first connect to each
CSAT3B as described in Section 7.1,
Settings
,
to ensure each sensor has been
assigned a unique SDM address. Connect a CSAT3BCBL1 to the
Power/SDM
port of the terminal CSAT3B.
The opposite end will have an
M16 connector that mates with one of the split M16 connectors on the
Power/SDM splitters (pn 30293).
Next, screw the side of the splitter with only
one M16 connector to the
Power/SDM
port of the second CSAT3B.
Connect
another CSAT3BCBL1 to the splitter and down to the next CSAT3B.
Continue the daisy-chain until the last CSAT3B.
The final CSAT3BCBL1
should have pigtail wire ends to connect to the
SDM
and
12 V
ports of a
datalogger.
If several CSAT3Bs using SDM communications are being connected in
parallel or with a star topology, connect a CSAT3BCBL1 cable to the
Power/SDM
port of each CSAT3B, and connect the other wire leads on the
pigtail end of the cables to a HUB-SDM8 bus (see Section 5.2.4.3,
HUB-
SDM8
).
Connect the wires so that all wires of a common color or signal are on the
same rail.
Then, use a CABLE5CBL with pigtail wire leads to connect the
HUB-SDM to the
SDM
and
12 V
ports of a datalogger.
