ROS
The Raven Operating Software, or ROS, assists with managing an implement fleet and multiple equipment
operators.
Secure User Login
Multiple user profiles allow the system administrator to set up unique Personal Identification Numbers (PIN) to
secure the application system from unauthorized use. As well as secure access, each user profile may
configure various user preferences such as language and display units to ensure that each operator is
comfortable operating the system.
Widget Based Field Operation Displays
The ROS features widget based screens for field operation and guidance. The operator may select from
various widgets to customize the information displayed on the screen during field operations and may
customize the widget layout to keep important operation information or operation tools available at a glance.
Each screen profile may be saved and recalled quickly to view additional information as necessary or as
different tasks become more critical for the field operation.
Note: Refer to the Raven Operating Software (ROS) Basic Operation Manual for additional information
about creating, saving, and using screen widget profiles.
Machine Configurations
Machine Configurations allow the system administrator to configure multiple machine profiles. As the ROS
device is moved from implement to implement, the device will automatically detect the machine configuration
for the implement on which the device is currently running to simplify set up and preparations for field
operations.
Product Configurations and Job Profiles
Preconfigured product configurations and job profiles allow the system administrator to set up product and job
information and allow the operator to quickly select the product loaded and the job or operation to perform to
begin field work.

Viper® 4 and 4+ Introduction and Technical Specifications
Enclosed Display
The Viper 4 and Viper 4+ enclosures are designed to resist the conditions experienced in the field to help
ensure that the field computer is ready to operate when you are. The enclosed case design provides dust and
splash resistance, even in open or exposed cabin vehicles and tractors. The lightweight magnesium alloy
provides excellent heat transfer properties to keep the Viper 4 and Viper 4+ operating efficiently, even in direct
sunlight.
Note: The case is designed to allow a small air gap 1/8 inch [3 mm] between the mounting bracket and
the case to allow air flow over the case cooling fins. Do not seal or obstruct this air gap, or
otherwise modify the case.
It is normal for the case to become warm to the touch while in operation.
Touch Screen
Viper 4
Transflective screen technology provides clear screen visibility across a range of lighting conditions and even
in direct sunlight. Resistive touch screen functionality places menus and options at the operator’s finger tips. A
12.1 in. [30.7 cm] high resolution display provides a large viewing area and easy to read display that allows the
operator to quickly reference information during in field operations.
Viper 4+
In addition to the standard Viper 4 features, the Viper 4+ utilizes an enhanced brightness display and a
Projected Capacitance (PCAP) touchscreen for added visibility and functionality.
Two and Three Dimensional Field Operation Views
During field operations, the Viper 4 and 4+ provide either a two or three dimensional view of the equipment
location within the field area. The ROS is capable of providing swath guidance for the configured equipment
using the configured equipment geometry to assist the operator and keep the equipment on track during the
field operation.
Note: Swath guidance may also be used by automated steering systems such as Raven SmarTrax to
automatically steer the equipment onto the displayed swath guidance line. These systems are
available to help reduce operator fatigue and can allow the operator to monitor various input or
application systems during the field operation.
Contact a local Raven dealer for additional information about automated steering systems
available for use with the Raven Viper 4.
On-Screen Mapping and Job Reporting
During field operations, the Viper 4 and Viper 4+monitors and tracks the vehicle location and records input or
application systems. As active sections or the working equipment width covers field area, the Viper 4 and Viper
4+ create live maps of previous equipment coverage. When the job is complete, the Viper compiles the
location and any population, rate, or yield information into a report file for transfer to a home or office computer.
The reports may be edited and used for customer billing, tracking product input or application for governmental
agencies or environmental purposes, or to help plan future crop inputs and field operations.
