NOTE:
l
The SDM-SIO2R Input connector can handle wire sizes ranging from 14-28 AWG.
l
The SDM-SIO2R6- Pin and 4-pin sensor communication connectors can handle wire
sizes ranging from 16-24 AWG.
o
When using 20-24 AWG ferrules on the SDM-SIO2R 6-pin communication
connectors, longer ferrules must be used (for example, Campbell Scientific pn
40233).
If necessary, a connector can be removed from the device by unlocking the slide bar. See
Figure 6-7. Connector release slide bar
NOTE:
The 12V power ground for the SDM-SIO2R must be common ground with the data logger in
order for the C1/C2/C3 communications to work.
