5.3.1.1 Method 1: Define the Endpoints

The host can configure the scaled integers just by defining the endpoints (x

1

,y

1

 and x

2

,y

2

) 

for the line shown Figure 5-1 .

The 3095FB will reject endpoints that do not conform to the following limits.

The values for x

1

 and x

2

 should be configured for the current unit codes. If the host 

changes unit codes after the scaled integers are configured using Method 1, the values for 
x

1

 and x

2

 will be changed to reflect the new unit codes.
