3. A Tour of IVNT-03 Hardware

Warning

Warning: Do not attempt to open the case unless specifically instructed to do so by an Intrepid Control Systems technician, or you risk possible injury or damage to the unit.

3.1. Case and Overall Design

The IVNT-03 is enclosed in a sturdy, black-anodized metal case.

The label of the IVNT-03 contains reference information, including the device serial number, pinouts of its DB-9 connectors. Pinouts for the IVNT-03’s connector and cables can be found in Chapter 8.

There are 2 LEDs on the device signifying status of the device power and the vehicle power.

3.2. Front Side Interfaces and Connectors

The front side of the IVNT-03 contains the following components from left to right: the Micro DB-9 Connector, USB host port, USB “B” connector, microSD Slot, a set of green LEDs, Gnd offset banana jacks, HS CAN banana jacks, HS CAN termination selector, MS CAN termination selector, MS CAN banana jacks, and a vehicle GND banana jack.

3.2.1. μDB-9 (Micro DB-9) Connector

This connector carries LIN and miscellaneous I/O signals to and from the INVT-03. A micro DB-9 was used to allow the device to be made more compact; a provided cable converts from this smaller connector to the standard DB-9 commonly used in the automotive industry.

3.2.2. USB “B” Connector

This is the “square” connector for USB devices that use detachable cables. (The standard “rectangular” connectors found on PCs are “A” connectors, which is why the cable supplied with the IVNT-03 is often called a “USB A/B cable”.)

3.2.3. USB Host Port

The USB “A” connector allows the IVNT-03 to act as a USB host, so other devices can plug into it. Please see Section 6.2 for more details.

3.2.4. microSD Slot and Cover

This slot holds the microSD card that stores data logged or captured by the IVNT-03. You can download the contents of the installed microSD card over USB, or for larger data sets, remove the card and use the provided external card reader.

3.2.5. Green LEDs

The IVNT-03 must be powered by an external 12 volt adaptor. The top LED will be lit when the IVNT-03 is powered by the external power adaptor. The bottom LED will be lit when the vehicle battery is connected to the HD26 pin connector on the rear panel.

3.3. Rear Side Interfaces and Connectors

Contains three components: the HD-26 connector, the power connector, and the power switch.

3.3.1. HD-26 Network Interface Connector

This male, high-density, 26-pin D-subminiature connector is the primary means by which the IVNT-03 interfaces with vehicle networks. One of two network interface cables is connected to this port, enabling CAN, LIN and Ethernet messages to be passed between the network and the IVNT-03. This connector also provides vehicle power to the device.

3.3.2. Power Connector

This is the round connector for the 12 volt power adaptor.

3.3.3. Power switch

This rocker switch controls the IVNT-03 power from the 12 volt power adaptor. It does not affect the vehicle power.

3.4. Cable Options

There are three cables available for the IVNT-03. These cables include the OBDII Cable, Deutsch 9 Pin, and CAN Channel Splitter.
