e CR206, CR211, and CR216 dataloggers replaced the CR205, CR210, and CR215 dataloggers on September 15, 2005. e newer dataloggers
re ect changes incorporated in the RF401, RF411, and RF416 Spread Spectrum Radios, which replaced the RF400, RF410, and RF415 radios in
May 2005. e newer dataloggers can be con gured to be used in systems that contain the retired dataloggers and retired radios.

Campbell Scienti c is increasing the nal storage memory from 128 kbytes to 512 kbytes. Dataloggers with the increased memory have 512k on
their label.
Features
Campbell Scienti c’s smallest, lowest cost datalogger•
Optimal for measuring one or two simple sensors•
512 kbytes of Flash nal storage memory; approxi-•
mately 128,000 data points
2
Fastest scan rate of once per second•
12-bit analog to digital conversions•
Gas Discharge Tube (GDT) protected inputs•
Data values stored in tables with a time stamp and •
record number
Battery-backed SRAM and clock that ensure data, •
programs, and accurate time are maintained while
a CR200-series datalogger is disconnected from
the main power source
PakBus® communication protocol used, which is a •
simpli ed variation of Internet protocols.
Input/Output Channels
Gas discharge tubes provide rugged electrostatic
discharge protection for the inputs. The CR200-
series loggers have five single-ended analog inputs,
one switch closure pulse input, one low level ac
pulse input, two control ports, two excitation chan-
nels (2.5 or 5 V), and one switched battery output.
One of the control ports can be used as an SDI-12
port. Input voltage range is 0 to +2500 mV with
0.6 mV resolution. Please note that differential
measurements are not supported.
Program/Data Storage
Programs and data are stored in a non-volatile Flash
memory. Final storage has 512 kbytes of memory that
provides approximately 128,000 data points in the
table-based memory structure.
{
Antenna Connector:
Connects to a whip
antenna or an antenna
cable (CR206, CR211,
and CR216 only).
Input/Output
Connections:
Measure, commu-
nicate with, and
power sensors.
LEDs: Indicate
datalogger is scan-
ning, transmitting,
or receiving.
RS-232 Port: Supports
communications with a com-
puter. The CR295 has a second
serial port dedicated for satel-
lite communications.
