Campbell Scientific CR200/CR200X-series Dataloggers - Manual (Page 144)

Section 13. Telecommunications and Data Retrieval
NOTE: The CR200(X) operates at a baud rate of 9600 baud. Attempting to
connect at a higher baud rate will result in communications errors.
13.2 Protocols
The primary telecommunication protocol for the CR200(X) is PakBus ( PakBus
Overview (p. 133)). ModBus is also supported on board ( Alternate Telecoms
Resource Library (p. 139)).
13.3 Initiating Telecommunications
Telecommunications sessions are initiated by a PC running Campbell Scientific
datalogger support software ( Support Software p. 143). Once
telecommunication is established, the PC issues commands to send programs,
set clocks, collect data, etc. Because data retrieval is managed by the PC, several
PCs can have access to a CR200(X) without disrupting the continuity of data.
13.4 Data Retrieval
Data tables are transferred to PC files through a telecommunications link
( Telecommunications and Data Retrieval (p. 131)).
13.4.1 Via Telecommunications
Data are usually transferred through a telecommunications link to an ASCII file
on the supporting PC using Campbell Scientific datalogger support software
( Support Software (p. 143)). See also the manual and Help for the software
package being used.
13.4.2 Data Format on Computer
CR200(X) data stored on a PC via support software is formatted as either ASCII
or Binary depending on the file type selected in the support software. Consult
the software manual for details on the various available data file formats.
