Matrix Orbital GLK12232-25-SM - Manual (Page 39)

Description This command shifts the strip chart left or right. [ref] determines both
which strip chart is used and which direction it will shift. The direction
is selected by the most significant bit (MSB):
• MSB: 0 shifts left
• MSB: 1 shifts right
For example if [ref] is 1:
• 254 107 1 (hex FE 6B 01) shifts left
• 254 107 129 (hex FE 6B 81) shifts right
This command shifts the contents of the area defined in the Initialize
