Descripción detallada
The SW12 provides similar functionality as a data logger's switched 12 V terminal. Therefore, this power switch is typically used with older data loggers (e.g., CR510, 21X, CR7) that do not have a switched 12 V terminal.
The SW12V consists of a cable that connects to the data logger, and a terminal block for connecting the external device.
The SW12V has a shrink wrap that lists the function of each wire by color. Wiring to the power source should be red to positive (12 V), black to ground, and green to control (on a Campbell Scientific data logger this is a control port labeled with a “C” or a universal port labeled with a "U."). Power out (to the device being powered) requires a 12 V connection and a ground connection.
Power is distributed to the remote device when the control wire is activated. Wire the power (+ lead) from the device being powered to a connection labeled “SW12V” on the SW12V green connector. Wire the ground (─ lead) to the G terminal on the SW12V green connector.

Because of the thread type used for the two sensors/rods, it is physically impossible to interchange the rods.
- The 20 cm rods used with the CS658 are not compatible with the CS659.
- The 12 cm rods used with the CS659 are not compatible with the CS658.
If measurements are needed for both depths, both the CS658 and CS659 must be used.
