Power In
•
Power Supply: External battery is connected to and Battery-
terminals. Review power requirements and power supply options in
CR200(X) Power Supply
(Appendix p.
30
)
before connecting power.
•
Input voltages in excess of 18 V may damage the CR200 and/or power
supply. Power to charge a 12 V lead-acid battery (16-22 VDC) must be
connected to the and Charge- terminals NOT to and
Battery-.
Power Out
•
Peripheral 12 V Power Source
: 1 terminal (SWBattery) and the associated
ground (G) supply power to sensors and peripheral devices requiring
nominal 12 VDC. Sensors and peripheral devices may also share a
connection to the and Battery- terminals which is the same as
connecting them directly to the battery. This supply may drop as low as 7
VDC before datalogger operation stops. Precautions should be taken to
minimize the occurrence of invalid data from underpowered sensors.

Overview
(p. 133).
The CR200(X) is equipped with an RS-232 communications port. This port
allows the CR200(X) to communicate with other computing devices, such as a
PC, or with other Campbell Scientific dataloggers.
Note
RS-232 communications normally operate well up to a transmission cable
capacitance of 2500 picofarads, or approximately 50 feet of commonly available
serial cable.
•
9-pin RS-232
: Non-isolated port for communicating with a PC through the
supplied serial cable, serial sensors, or through 3rd party serial
telecommunications devices. Acts as a DTE device with a null-modem
cable.

APPENDIX. Serial Port Pin Outs
(Appendix p. 21).
Some versions of the CR200(X) include an optional spread spectrum radio for
wireless communication with other devices equipped with a spread spectrum
radio.
