Cat® Terrain for Track-Type Tractor with Blade Control Caterpillar

Component Overview

The on-board system consists of machine hardware components and software components.

The hardware components include the following:

• G610 display module

• Miscellaneous harnesses and connectors

• MS952 Satellite receiver

• Implement ECM

System Software

The on-board software is the main application for displaying operating information to the operator.

The on-board software performs the following tasks:

• Calculates the position of the machine

• Determines the productivity of the machine

• Displays information about the site and about the machine movement to the operator

• Displays the task list

Hardware Components

The on-board software relies on the following hardware components:

• Satellite receiver

• Display module

• Harnesses and connectors

• Additional components

• Radio module (not supplied)

MS952 Satellite Receiver

The MS952 satellite receiver (1) consists of an integrated GPS/GNSS receiver and antenna. The antenna receives ranging information from the GPS/GNSS satellite constellation. The receiver calculates the machine position. The receiver uses the satellite data from the antenna and correction information from a reference station via the radio network.

With this type of system, the power is conditioned by a separate uninterruptible power supply (UPS).

Dual Receiver Systems

Dual receiver systems (also called dual antenna systems), such as those used on hydraulic excavators, use two receivers and calculate two separate positions.

When two receivers are on the same machine, the position of the left antenna on the machine is known as the master. The right receiver (looking forward from the seat of the operator) is known as the slave. The position of the master receiver is corrected by the data from the reference receiver coming through the radio network. The position of the slave receiver is calculated relative to the position of the master receiver. Both receivers send a position to the display module.

Display Module

The display module (2) is mounted inside the cab. The module consists of a touchscreen LCD display and an integrated computer that runs the on-board software. The touchscreen display utilizes several small adjustable windows. The windows display the appropriate information for any given machine.

Management personnel configure toolbars with tools that help operators easily adjust the views of the display module.

Reference: For additional information on configuring the tools that are used in the on-board software, refer to Systems Operation, KENR8277, "Cat^® Terrain for Grading and Loading", "Display Configuration Tools".

The display module performs many functions, including the following:

• Displays information about the site and the machine movement to the operator

• Enables machine operators to send productivity messages to the office

• Manages power up and power down of the system components

• Manages system communications

• Provides data to the operator about the system

• Provides an interface between the on-board software and other systems on the machine

• Calculates information about machine movements

• Diagnoses errors in the system

Harnesses

The following harnesses are included:

Main harness - Connects the satellite receiver and the display module

Machine interconnect - Connects the machine battery +, battery -, and the RUN terminal of the keyswitch to the main harness

Interconnect - Connects between the on-board radio module and the satellite receiver

Additional Components

The following are additional components:

• Measurement sensors (pitch, angle, slope, and others), as required

• Service connections for a keyboard and a serial cable

• Wiring harnesses to connect power and the main hardware components

Reference: For additional information regarding the machine hardware components, refer to the Installation Special Instruction for your machine and Systems Operation, KENR8277, "Cat^® Terrain for Grading and Loading", "System Components".

Radio Module (not supplied)

A radio module is not supplied with Terrain. The 389-0333 Cable As (radio Ethernet) connects to the 383-3028 Wiring Harness (main rear) using a 12-pin (key D) connector. The opposite end of the radio harness employs a standard RJ-45 Ethernet connector with power provided through the connector for a third-party radio.

The on-board radio module provides communications with Cat MineStar System. The radio module also receives position corrections from the reference station. The radio module has two ports for communication. The first port receives position reference data. This data is passed to the receiver in the satellite receiver. The second port provides data communications between Cat MineStar and the display module.

Reference: For detailed information regarding use of a customer supplied radio for Terrain or a TC900x radio for CAESultra, refer to Systems Operation, KENR8277, "Cat^® Terrain for Grading and Loading", "Machine Hardware".

Radio Network Status

The on-board software provides the operator with visual information about the radio network status and records the status in diagnostic files. The status appears in the following three ways on the display module:

• Text in Digital windows

• Color of Digital windows

• "FTP File Transfer Diagnostics" window

The network status appears as specific text or as a specific background color in a digital window.

In Illustration 2 the text indicates "Network Up" against a green background.

Table 1 shows the text and the associated background colors used in a digital window.

Illustration 3	g03367662
Left-hand top of Terrain window

The network status also appears as shown in Illustration 3 in the "FTP File Transfer Diagnostics" window. Table 2 shows the text and the associated colors used in the window.

The on-board software manages the situation where a network is down in the following ways:

• For an FTP network, the on-board software suspends file transfer to the office.

• For networks that use file transfer over TMAC, the on-board software continues to try to send the file.
