Configuring the Ruler
3.1
Configuration Hierarchy
The following information uses the same hierarchy as in the parameter editor in Ranger
Studio. This means that the settings are grouped into the following configurations:
Ethernet
Set-up of the communication between the Ruler and the PC.
System
Set-up of the Ruler system.
Image
Used when the Ruler is running in Image mode, for example for setting up
of Region-of-Interest.
Measurement
Selection and set-up of the measurement method to use when measuring
profiles.
Which measurement method to use is specified by the measurement
component that is included in this configuration.
3.2
Ethernet Configuration
The Ethernet configuration is used for communication set-up.
Redundancy packages are used for recovering lost packages and can be used for safer
communication between the Ruler and the PC. Each redundancy package can be used for
recovering one lost package since the previous redundancy package was sent. For exam-
ple, if
Redundancy frequency
is set to 10, one package out of ten can be lost without
losing any data.
The maximum package size depends on whether or not the Network Interface Card in the
PC and all other equipment involved in the communication can handle Ethernet “Jumbo
frames”.
Input parameters
Redundancy frequency
Number of data packages sent between each redundancy
package 0 – 100. Default value 10.
A low value means higher security but also higher load on
the PC.
Max package size
States the maximum size of the Ethernet data package.
The bigger the package – the lower the CPU overhead for
the communication. 100 – 4054 bytes.
Default value 1472.
1472 Maximum size without Ethernet Jumbo frames.
4054 Maximum size if all equipment can handle
Ethernet Jumbo frames.
3.3
System Configuration
The System settings are used for switching the laser off in order to increase the laser’s life
time.
Input parameters
Laser On
Laser Off/On. 0 – 1. Default value 1.
0 = Laser Off.
1 = Laser On.
