Campbell Scientific CDM-VW300 Series Dynamic Vibrating-Wire Analyzer System - Manual (Page 56)

CDM-VW300 Series Dynamic Vibrating-Wire Analyzers
• These dataloggers get into a state wherein they measure and store so
intensely that little time remains to communicate with LoggerNet or
RTDAQ software.
The CR3000 datalogger is the only datalogger currently available (as of August
2013) that will allow near real-time monitoring of events.
7.8 Operating System
The following components of a dynamic vibrating-wire data-acquisition system
require an operating system (OS):
• CDM-VW300 series analyzer
• Datalogger
• SC-CPI interface
Operating systems may be updated on occasion to address new or enhanced
features, or bugs fixes. The frequency of updates decreases as a product
matures. If a product is received within six to twelve months of its first
shipment, check the operating system identifiers against those listed at
www.campbellsci.com/downloads upon receipt. The CDM-VW300 series
analyzers and SC-CPI interface were first shipped in April of 2013.
Updating an operating system usually clears all settings. Always
save the current settings of the device before loading an
operating system. NOTE
Use DevConfig to update the CDM-VW300 operating system. In the
DevConfig CDM-VW300 option, check the operating system version in the
Settings Editor tab. Download operating system updates in the Send OS tab
by following the instruction outlined therein.
7.9 Power-Up Sequence
Switch power to the CDM-VW300 analyzers, the datalogger, and the SC-CPI
interface simultaneously.
If powering devices sequentially is necessary, first switch power to each
analyzer. The COMM Status LED on each analyzer will flash orange,
meaning that the device has not yet established a connection with the SC-CPI.
Next, switch power to the datalogger and the SC-CPI. The SC-CPI will begin
initializing the CPI network. The COMM Status light on the analyzers may
flash both green and red intermittently. When the SC-CPI is finished
initializing the network, the CPI Status and Serial Status LEDs will flash
green, as will the COMM Status light for each analyzer. If initialization fails,
LEDs on all devices will flash red.
If the datalogger or SC-CPI interface loses power, and the CDM-VW300
analyzers do not, the COMM Status light on each device will change to red
indicating that the connection to the CPI network is lost. Usually, restoring
power to the datalogger (assuming it is still running a CDM-VW300 enabled
program) and SC-CPI will automatically reinitialize the network.
