DESCRIPTION
IHMI v2
Open embedded solution for onboard vehicle computing and multimedia applications
The IHMI v2 is a compact and cost-effective solution for equipping transport systems. It can be installed in
buses, coaches, or light vehicles.
Based on a PC compatible architecture, the computer is easy to implement. Its innovative mechanical design
and safety system allow fanless operation.
System specifications
This panel is composed of a case, a 7” 800x480 TFT display with LED backlight and a resistive touchscreen.
It also includes an embedded computer based on the Intel BayTrail processor, a GPS and a stereo audio
amplifier with one microphone and two loudspeakers.
The PC architecture is composed of an IHMI-MPC baseboard with an MPC form factor processor board.
System functions are described in the IHMI-MPC user’s manual (DOC02097) and MPC-BayTrail user’s
manual (DOC02106).
This basic system can be equipped with extensions (WiFi, Bluetooth etc.). A dedicated location is provided to
receive a GSM (GPRS/EDGE/2G/3G) optional module.
Optionally, an external Mixing Panel PDB (DOC08024) can also be used with the IHMI v2 in order to add
remote interfaces such as serial com ports, automotive inputs/outputs, CAN Bus, audio Line out/microphone,
etc…
General specifications
Electrical:
12 or 24V power supply voltage (8V to 36V Max)
Computer consumption : 15 W max. with extensions
Environmental:
Operating temperature: -40°/ +65°C (*)
Storage temperature: -40 / +85 °C
Relative humidity: 10 to 90% without condensation
Relative humidity: 5 to 95% without condensation (storage)
Dimensions:
Case : 196 x 124 x 57 mm
(*) - Internal operating temperature is deliberately limited to 85°C, this temperature corresponds to a ca se
temperature of approximately 65°C. Beyond this limit, the internal power supply is turned off to prevent
the system to operate outside the component manufacturers' specifications.
- In similar manner, the power supply is turned off when the internal temperature is less than -40°C.

BIOS setup
As a PC compatible system, the BIOS includes a SETUP utility. An USB keyboard is required to access it.
If the initialization messages are not disabled (Quiet boot : No): SETUP is enabled by pressing the <Del> key
within 3 seconds after the corresponding prompt message or the logo is displayed. If an error is detected on
the POST, the <Del> key enables the SETUP and the <Esc> key is used to continue without SETUP.
If the initialization messages are disabled (Quiet boot : Yes): SETUP is enabled by pressing the <Del> key
within 1 second after the 'System loading …' message or the logo is displayed.
SETUP cannot be entered if its access is locked (locked or absent keyboard, missing or faulty display). It
consists of a menu and dialog boxes. The top part of the screen describes the computer resources. The first
line indicates the title and the last line displays current help on the keys.
If the SETUP parameters are updated, both the CMOS and the E2PROM memories of the processor board
are updated. The E2PROM acts as a backup memory for CMOS and is read by the POST if the CMOS is
faulty.

- Do not introduce a thin rod in a LED hole. It will damage the LED.
DOC 02110-1 ACTIA PCs Page 19 / 52
INSTALLATION
Cautions
- This system is designed for negative ground 12V or 24V operation only.
- To avoid IHMI v2 damage, remove the battery power before connecting (or disconnecting) the mixing
panel connector. This can be done by removing the PDB fuse.
In this configuration, the IHMI v2 is automatically powered up when the vehicle ignition is switched on. When
the ignition is switched off (for more than 10 seconds), the operating system is notified in order to shut down
properly. After shutdown, the IHMI v2 is powered down.
Note: If the system does not shut down within 10 minutes (standard profile or 45 minutes with aggressive
profile or 4 hours with relax profile) after the ignition was switched off, power down is forced to preserve
battery life.
If IHMI v2 cables are not fully installed, the antenna cables, the mixing panel and Ethernet cables and the
cable cover must be set following the next 3 paragraphs.
DOC 02110-1 ACTIA PCs Page 20 / 52
Antenna cables
The GPS, GSM and WiFi antenna cables must be attached to the IHMI v2 housing. They are maintained by a
bridge and a screw (tightening of 0.6Nm). The unsheathed portion of the antenna cables must be located
under the bridge.
Antenna cables Bridge M2.5x6 Torx screw (cylinder head)
Bridge
A multi-function antenna must be mounted on the roof of the vehicle. A separate cable must be installed for
each function. Use the shortest possible length of antenna cable.
