Section 4. The RTDAQ Main Screen
4.6.3 Datalogger Menu
4.6.3.1 Connect/Disconnect
This option provides the same function as the Connect/Disconnect button on
the main toolbar (see Section 4.7).
4.6.3.2 Update Table Definitions
When a CRBasic datalogger is configured for the first time or when a new
program is sent, RTDAQ queries the datalogger for its table definitions.
Whenever a new program is loaded into the datalogger, the table definitions
will automatically be sent to RTDAQ. When using the real-time screens to
view data, RTDAQ requires the latest table definitions in order to work
properly. To avoid unnecessary data throughput on a datalogger, this
information is not sent to RTDAQ with every configuration change, but only
when deemed necessary, such as when a program changes.
If you find the table definitions in RTDAQ to be mismatched with the
datalogger program, you can update those definitions manually. To update the
table definitions for a datalogger manually, connect to that datalogger and
select Update Table Definitions from the Datalogger menu.
4.6.3.3 Status Table
CRBasic dataloggers include a default data table called the Status Table, which
displays key values about the condition of the datalogger. The Datalogger |
Status Table menu item opens a window to display that information. Records
from the datalogger’s status table are generated on demand. Each datalogger
has its own list of status fields, but they typically include such information as
the hardware operating system version, the name of running program, battery
voltage, various error counters including watch dog and low battery
conditions, and an estimate of how many days it will take for data tables to
begin overwriting their oldest records. Detailed information on the status table
for each datalogger can be found in the operator’s manual for that particular
datalogger.
