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.
