Select colour palette where x = 0 to 5 

 

 

 

 

0 = white hot, 

 1 = black hot, 

 2 = ironbow 

 

 

 

 

3 = inverse ironbow, 4 = red-black, 

 ‘5 = black-red

Zoom mode where L = zoom level 0 to 2,  

0=X1, 1=X2  2=X4 

xxx,yyy = top left corner of picture. 

For e.g. >0Z2080080 

For L= 0 i.e. zoom x1 the top left hand position  xxxyyy is not
