Using Removable Media to View and Capture Screens

The XL7 OCS File System uses bitmap files with the .BMP extension or JPEG files with the .JPG extension

to store XL7 OCS graphic screen captures.

To view a captured XL7 OCS screen, use the Removable Media Manager to find and highlight the desired
.BMP or .JPG file, and then press Enter.

To capture an XL7 OCS screen, turning On the assigned Screen Capture Control Register will capture the

current XL7 OCS graphics screen and write it to the MicroSD card using the assigned Screen Capture

Filename.

Before capturing an XL7 OCS screen, Cscape must first be used to assign a Screen Capture Control

Register and Filename in the application. To do this, first open the Graphics Editor by selecting the View

/ Edit Screens item on the Cscape Screens menu. Next select the Screen Capture item of the Graphics

Editor Config menu and then enter a Control Register and Filename.

must be limited to the “8.3” format where the filename contains eight characters a period then a three-

character extension. The entire filename including any path must be less than or equal to 147
