GO8 RUGGED support document

Technical specifications and installation instructions for the GO8 RUGGED device.

Geotab GO8 RUGGED — Ruggedized Telematics Device

The GO8 RUGGED is a ruggedized telematics device that offers state-of-the-art GPS technology, g-force monitoring, Geotab IOX expandability, and engine and battery health assessment with the added feature of communicating on the LTE network. Geotab’s patented tracking algorithm accurately recreates vehicle trips and analyzes incidents. The GO8 RUGGED is ideal for: heavy equipment, yellow iron, agricultural machinery, and oil field equipment; the tracking of powered trailers and assets; and installations where the Geotab GO™ device is exposed to the elements.

Over The Air (OTA) Support

Firmware Updates: For maintenance, new features, and custom applications

Parameters: For turning additional features on/off

Almanac/Ephemeris Data: For quicker GPS latch

Voltage Recording

Curve-based voltage logging to detect weak batteries, failing alternators, and failing starters.

32-Mb Non-volatile Flash Memory

Main Data Memory: Up to 80,000 logs in offline mode (out of coverage)

Accident Data Memory: Buffer records over 100 minutes of second-by-second data

(6,000 logs). Last 72 records (1.2 minutes) are sent instantly on accelerometer-triggered accident-level events.

Recording Parameters

Patented curve-based GPS/voltage/accelerometer/engine data logging algorithm for fewer, more accurate data points.

Can be downrated to a basic trailer tracking configuration.

Intelligent Ignition

Non-engine-based ignition detection voltage and movement, allowing for 3-wire installation. Ideal for older vehicles with no engine information and covert installation for asset recovery.

Differences between GO8 and GO8 RUGGED

Engine communication

The GO8 RUGGED does not support the following engine protocols and corresponding engine information:

  • Single-wire CAN: Seat belt and odometer data on some GM, Fiat, and Dodge vehicles

  • Medium speed CAN: Ford Transit and Mazda seat belt.

Buzzer and other IOX add-ons

The GO8 RUGGED is made for external environments and can be installed outside of a vehicle; as such, there is no internal buzzer. The IOX-BUZZ (external buzzer) or IOX-GOTALK can be installed if driver feedback is required. The HRN-RX06S4 is required to install any IOX.

Harness options

The GO8 RUGGED requires the following harnesses for successful vehicle and/or IOX installation:

  • HRN-GR09K1 — Universal Rugged Heavy-Duty T-Harness Kit (IP67)

  • HRN-RMRCA1 — Required for connecting to CAT vehicles (also requires HRN-GR09K1)

  • HRN-RS12S2 — Required for connecting to the vehicle diagnostic port or to an existing harness.

  • HRN-RW03S4 — Required for connecting to an external power source

  • HRN-RX06S4 — Required for connecting your GO8 RUGGED to any IOX.

Harness pin diagram and description for ALDL and IOX

For professional installation where specific cable routing is required, the terminals on the weather-resistant connectors can be depinned on both the GO8 RUGGED and the corresponding HRN-RS12S2 and HRN-RX06S4 harnesses. This allows the installer to route the wires through a smaller opening. The wires can then be repinned into the connectors per the tables below. In this manner, the GO8 RUGGED can be installed in restricted spaces while maintaining its IP67 rating.

The GO8 RUGGED and its connectors are IP67-rated. The HRN-RX06S4 and HRN-RS12S2 are only IP67-rated in part, and the gray connectors are the only weatherproof elements. Removal of the gray connectors on either the GO8 RUGGED or its harnesses will reduce the overall weatherproofing of the system. The diagram below shows the scope of the weatherproofing for the GO8 RUGGED and its harnesses. IP67 rated parts are highlighted in blue.
