Commnd B – Upload a bitmap to the instrument

This command enables you to upload a 128 × 64 pixel bitmap that the
instrument uses as a ‘splash’ screen when you switch the instrument ON. You
can use this feature to include a special logo or other screen. The first byte of
the bitmap forms the top left corner of the screen.

Example

Transmit

B

Wait to receive

D

Command C – Clear bitmap

This command restores the instrument’s default ‘splash’ screen.

5.8

Command i - Screen dump

The screen dump tells the instrument to transmit binary data to the PC that
represents the screen that the instrument is displaying currently. The first byte
transmitted is for the top left corner of the screen.

The screen dump command cannot be used at intervals shorter than 2 seconds.
This delay is necessary to allow the data to be transmitted successfully.
