Configuring Power-Up State - Omega Engineering OMB-CHARTSCAN 1400 User Manual

Appendix C

Configuring Power-Up State

ChartScan has an internally stored factory default configuration that can be recalled at any time. You can
program the ChartScan to power-up in a "user-defined" state, or if desired, can configure the unit to power-up
with the default configuration.
During normal operations the factory defaults may be recalled by issuing the Restore Factory Defaults (*F)
command. When this command is processed, ChartScan loads the factory default configuration and operates
accordingly. This command, however, may not be issued while an acquisition is currently configured.
ChartScan is usually configured to power-up with the last known configuration (from when the unit was
powered-down). Last-configuration power-ups will also occur when a Power-On Reset (*R ) command is used.
You can configure the unit such that it will always power-up with the factory default configuration by issuing the
Power-up Settings (*S1) command. Note that issuing an *S0 (power-up under last-known configuration)
command causes the unit to power up under the last known configuration.
Note:
The following table lists the execution steps and effects when the ChartScan is configured to power-up under the
factory default configuration.
