3.3 Command Format<br />
3.4 Startup<br />
When entering commands, remember that:<br />
<br />
<br />
<br />
<br />
A carriage return (CR) ends each command.<br />
Values in square brackets are optional.<br />
The camera will answer each command with either a carriage return and line<br />
feed followed by "OK >" or "Error x: Error Message >". The ">" is always the<br />
last character sent by the camera.<br />
The following parameter conventions are used:<br />
t = tap number<br />
i = integer value<br />
f = real number<br />
s = string<br />
[ ] = optional parameter<br />
When the camera is first started, it must perform several actions before it is ready for<br />
imaging. This startup routine takes approximately 15 seconds, and follows this sequence:<br />
1. Initializes the camera and all internal hardware.<br />
2. Loads the last settings saved to non-volatile memory.<br />
3. Restores user settings if previously saved, otherwise factory settings.<br />
4. Performs a memory test and voltage test and reports an error if any occurred.<br />
After this startup sequence has completed, the camera will return either the prompt<br />
"OK>" if no error occurred, or an error code if a problem has been discovered.<br />
3.5 Saving and Restoring Settings<br />
The camera provides a number of commands for restoring, storing, and saving settings.<br />
<br />
To restore the original factory settings, use the command rfs.<br />
