RS-232 connection using a null modem cable
Null Modem Cable is used to connect the module to the CR3000, CR800, CR2XX, CR300
series, or CR1000 RS-232 port. Power is provided from the 12V or SW12V port of the data
logger.

CR1000X or CR6 RS-232 connection using a CPI/RS-232 cable
RS-232/CPI RJ45 to DB9 Male DTE is used to connect the module to the CR6 or CR1000X.
Power is provided from the 12V or SW12V port of the data logger.

6.3.2 Module power connections
When connecting through the CS I/O port, power for the module is provided by the data logger.
When connecting through the RS-232 port, power must be supplied through the Power In
connector.
Controlling power to the CELL200 series
(p. 58) provides an example CRBasic program using the
IPNetPower()
instruction to control power to the CELL200 series. This functionality is
available in the CR300 series (all operating systems), the CR6 series with operating system 09.00
or greater, and the CR1000X with operating system 03.00 or greater. To control power in these
data loggers with older operating systems or any CR1000, CR800 series, or CR3000, you will need
to use a SW12V port on the data logger and communicate over RS-232.
Alternatively, CR1000X series, CR300 series, CR6 series, CR1000, CR3000, CR800 series, CR5000,
and GRANITE 6/9/10 can use terminal commands to control power. Search for
