Pearl Mini User Guide Crop a video source
If you use a non-monospaced font, the size of the text overlay changes as the letters, numbers, and
the length of words change. Use a monospaced font to maintain a consistent size for the text overlay
(assuming the total number of characters in the text string doesn't change).
The RS-232 SET command syntax in this case is VAR.SET. <name> = <value> , for example:
VAR.SET.gpsvar1=N103 68201 W765 29712
where <name> is gpsvar1 and <value> is N103 68201 W765 29712.
There are no limits for the frequency of system variable commands using RS-232. However, only one command
can be issued at a time.
HTTP system variable commands are issued at a frequency of 5 per second. You can include up to six variables
in a single HTTP SET command. After issuing a SET command, all channels using the specified variables are
updated.
System variables are considered volatile. They are deleted when a Pearl system reboots.
To learn more about global variable command syntax and important considerations when using them, see the
Pearl System API Guide for details.
