Do not store the jumpers between any other pins in the
block as this may switch the module into a factory
calibration mode, which may result in abnormal operation
and change of output accuracy. CAUTION
The jumper settings can be overridden by the datalogger program, if required,
using special commands. Please contact Campbell Scientific for details.
4.4 SDM Address Setting
Each SDM-CVO4 can have 1 of 16 addresses. The factory-set address is 00.
Table 4-2 shows switch position and the corresponding address. Figure 4-4

you will have to remove the right-hand mounting bracket to gain access to this
switch.
