Errata for viewLinc™

viewLinc version 3.4.100.533

Issued April 26, 2010

General:

- To ensure data timestamp accuracy, verify that the viewLinc server time is set accurately before installing the viewLinc software. The viewLinc server and logger host should also be set to have its time synchronized with an accurate source once a day at a minimum.

- When entering text in various fields of the forms, it is necessary to tab out of the field or select another field for the new values to be saved.

Alarms:

- Ensure that the delay for Calibration Alarms is set to 0. This is to prevent artificial ballooning of the historical database.

- When a logger has been set to start in the future a communication alarm is generated instead of a configuration alarm.

System:

- On large systems (1000 or more channels) timing parameters in the configuration file may need to be modified to ensure optimum performance. Please see the readme file or contact Technical Support for more information if you are using a system of this size.

- When deactivating or reactivating loggers, the UI may timeout and report that the operation failed, even though it< succeed. Pressing the Refresh button on the System tab toolbar will update the tables to show the correct results of the operation.

- Ensure that only one viewLinc administrator is activating, deactivating or swapping loggers at a time.

Reporting:

- When a manual report is started during a time when scheduled reports are running or other users are generating
reports, the status of the manually generated report is listed as “Queued”. The status will remain “Queued” until the queue gets to this report. This could be a significant period of time depending on the size and quantity of reports already in the queue.

- Due to the time required to generate reports, it is recommended that scheduled reports be set up to start during nonpeak times and have at least 15 minutes between each report. This will reduce the chance of a scheduled report delaying a manually requested report. It is also best not to schedule reports with large data sets to start at the same time.

- For reports based on a fixed period in the past, alarm duration may be calculated incorrectly, if alarm deactivation was not covered by the report time range. The workaround for this is to try to extend report time range to include the entire lifespan of the alarm.

Logger Swapping:

- When swapping loggers it is important to allow the new Logger to come to equilibrium before placing it on the COM port. This will ensure that data recorded from outside of the environment is not included on reports.

Real-Time Display:

- In Channel View, vertical axis sometimes shows values formatted incorrectly (e.g. 10.10 instead of 11.0). There is currently no workaround for this.

- If a channel that used on a POS display is deactivated, the POS display will show "Host error", even though the rest of its channels are available. The workaround for this is to remove the channel ID from line for that POS display in the config file and then restart POS service.
