CDM-VW300 Series Dynamic Vibrating-Wire Analyzers
7.5.3 Operating System Version
This field reports the version of the CDM-VW300 operating system. This
setting is viewable only in DevConfig.
7.5.4 Operating System Date
This field reports the release date of the CDM-VW300 operating system. This
setting is viewable only in DevConfig.
7.5.5 Analyzer Serial Number
This field reports the serial number of the CDM-VW300. The same serial
number is on a tag on CDM-VW300 case. This setting is viewable DVWTool
and DevConfig.
7.5.6 Display Rate
This setting specifies the rate at which PC displays are updated. This is not an
option in the CRBasic datalogger instruction setup.
7.5.7 Dynamic Sample Rate
This setting is entered in units of Hz (hertz) in DVWTool and DevConfig.
Options are 20, 50, 100, 200, or 333.3 kHz. This is set for lab mode using
DVWTool. In field mode, it is determined automatically from the Interval
argument CRBasic program Scan() instruction. It is calculated for the Interval
parameter as:
Interval = (1 / DVWTool Scan Rate • 1000).
7.5.8 Device Type
This setting specifies whether the analyzer is a CDM-VW300 (Option 0) or
CDM-VW305 (Option 1).
7.5.9 CPI Bus Address
Each CDM-VW300 series analyzer must be given a unique address on the CPI
bus using DVWTool or DevConfig software. This address is used as the
argument in the CPIAddress parameter in the CRBasic program instruction
CDM_VW300Config(). For more information about the operation of the CPI
bus, see Appendix B, SC-CPI Datalogger to CPI Interface. Addresses range
from 1 to 120.
7.5.10 System Options
This setting determines if a numeric value or NAN will be stored in the
datalogger when a flag condition occurs, and whether or not the diagnostic
LEDs are on or off. This option is available for only the CRBasic datalogger
program. Options are 0, 1, 10, and 11.
