Chapter 1 Introduction
1.1 Overview
Introducing the most compact in-vehicle fanless controller supporting PGA-type 3rd-Gen
i7/i5 processor!
Neousys’ Nuvo-3100 series features the dimension of only 212 mm x 165 mm x 62 mm.
While other compact fanless controllers adopt low-voltage, BGA-type i7 CPU (17W TDP),
Nuvo-3100 supports standard voltage, PGA-type i7/i5/i3 CPU for flexible CPU installation.
To solve the trade-off between heat-sink size and operating temperature, a unique feature,
configurable CPU power mode, is developed for Nuvo-3100 series. According to ambient
condition, users can configure the system to operate in maximal performance, reduced
performance or extended temperature mode.
Plenty of I/O functions, such as Gigabit Ethernet, USB 3.0, SATA, COM ports, mini-PCIe
and isolation DIO are provided in Nuvo-3100’s compact chassis. Nuvo-3100 series
supports 8~35V DC input to be deployed in various environments.
As the designated model for in-vehicle applications, Nuvo-3100VTC further integrates IEEE
802.3at PoE, intelligent ignition power control and a hot-swappable HDD tray. It carries
E-Mark to meet the requirements of European UN regulations for in-vehicle usage.

2.2 Front Panel I/O Functions
On Nuvo-3100 series, plenty of I/O functions are provides on front panel and back panel so
you can easily access them. Most common computer I/O functions are placed on the front
panel. In this section, we’ll illustrate each I/O function on the front panel.
2.2.1 Power Button
The power button is a non-latched switch for ATX mode on/off operation. To turn on the
Nuvo-3100VTC/3120, press the power button and the PWR LED is lighted up. To turn off
the Nuvo-3100VTC/3120, you can either issue a shutdown command in OS, or just simply
press the power button. In case of system halts, you can press and hold the power button
for 5 seconds to compulsorily shut down the system. Please note that a 5 seconds interval
is kept by the system between two on/off operations (i.e. once turning off the system, you
shall wait for 5 seconds to initiate another power-on operation).
2.2.2 Reset Button
The reset button is used to manually reset the system in case of any abnormal condition.
To avoid unexpected operation, the reset button is hidden behind the front panel. You need
to use a pin-like object to push the reset button.

2.2.5 USB 3.0 Connectors
Nuvo-3100 series offers four USB 3.0 (SuperSpeed USB) ports on its front panel. By BIOS
default, these USB ports are operated in xHCI (eXtensible Host Controller Interface) mode
and are compatible with USB 3.0, USB 2.0, USB 1.1 and USB 1.0 devices. Legacy USB
support is also provided so you can use USB keyboard/mouse in DOS environment. To use
USB 3.0 ports in Windows environment, you need to install corresponding USB 3.0 driver.
Please refer to section 4.4 for information of driver installation.
Note
1. Intel USB 3.0 driver does not support Windows XP. In Windows XP, all USB 3.0 ports will work
in USB 2.0 mode.

2.2.7 DVI/HDMI Connectors
Nuvo-3100 series supports triple independent display outputs via a DVI-I/HDMI connector
(front panel) and two DisplayPort connectors (back panel). The DVI-I connector on the front
panel offers DVI/HDMI and VGA display outputs. The DVI/HDMI output can be either DVI
signals or HDMI signal depending on the display device connected and support up to 1920
x 1080 resolution. The VGA output supports up to 2048x1536 resolution.
For VGA monitor, Neousys offers a dedicated DVI-to-VGA adapter as an accessory
shipped with Nuvo-3100 series. This adapter supports VGA DDC signals and thus
eliminates compatibility issues with VGA monitors. Or you can use a DVI-I to VGA+DVI-D
Y-cable to support two independent display outputs.
DVI-to-VGA Adapter DVI-I to VGA+DVI-D Y-Cable
Due to the limitation of Intel® QM77/HM76 PCH, the feature of triple independent display
outputs is only available via the configuration of DVI+DisplayPort+DisplayPort or
VGA+DisplayPort+DisplayPort. You also need to install corresponding graphics driver for
Windows XP/7/8 to enable this feature. Please refer to section 4.4 for information regarding
driver installation.
Note
If you want to connect to a VGA monitor via DVI-I connector, please use the DVI-to-VGA adapter
shipped with Nuvo-3100 series. Some off-the-shelf DVI-to-VGA adapters may have incompatible
pin definition and cause compatibility issue with DVI-I output of Nuvo-3100 series.

IGN Ignition signal input. Connected to ACC power of vehicle
Caution
1. Please make sure the voltage of DC power is correct before you connect it to
Nuvo-3100VTC/3120. Supplying a voltage over 35V will damage the system.
2. The IGN input accepts ACC power of car (12VDC) or bus/truck (24VDC). Supply a voltage
over 35V to IGN input to will damage the system.
