G150 Trip Modes & Overview of Operation
Published November 30th, 2023 by Brandon MacKenzie
Extended Trip Modes Overview For firmware version 1.4 and earlier on the G150, the G150 uses exactly the same trip mode configuration as most other hard-wired devices. For firmware version 1.5 and later, the G150 has extended operational modes. For the basics on hard-wired device operations, see Hard-Wired Devices: Overview of Operation. 1. Two Trac
Default I/O Mappings [G150]
Published November 27th, 2023 by Brandon MacKenzie
These are the Default I/O Mappings for the G150. You can change some of these mappings on OEM server; however, we do not recommend changing these unless you know what you are doing. Additionally, some firmware features provide their 'result' as a Digital Input flag - i.e. Idling flag. It is important when configuring these inputs to avoid clashing w
Configuring Ground Mode When Unlocked
Published December 8th, 2025 by Brandon MacKenzie
Note Some of the configuration options in this article require the unlocking of Ground Mode using an async message. This applies for devices running Fw v1.7+. For configuration options on locked devices (default), see this article. The Griffin Air features ‘Ground Mode’, which is an advanced detection mechanism for determining whether a device is in
G150 Harness Definition
Published November 27th, 2023 by Brandon MacKenzie
The G150 has two harness headers, which cover 10 pins each. The G150 comes with a single harness. This covers powering the device plus commonly used IOs. If the application requires additional IOs - the second harness should be purchased when ordering G150s. Both harnesses are identical and can be used as either Harness 1 or Harness 2. Specificatio
G150 - How does it compare to the G120?
Published February 13th, 2024 by Brandon MacKenzie
In many ways, the G150 is one of the natural successors to the G120. Therefore, the functionality of the two devices is interchangeable in many cases. However, there are a few variations and additions to highlight. Connectivity The G150 is part of our Global device range (Cat1-bis + 2G fallback). This differs from the G120 which comes either as a 2G
G150 Accelerometer Sampling
Published November 20th, 2023 by Brandon MacKenzie
Application The G150 can be configured to capture accelerometer data continuously. This is useful for intensive kinematic analyses. By continuously sampling the acceleration of a device, it is possible to reconstruct the orientation and movement of an asset, or assess the impacts, vibrations and forces endured by it. In doing so, it is possible to m
