Robust, Stylish and Extremely Small
You should have held it in your own hands to experience how small it
actually is. Barely 1.35 litre in volume, its rigid steel chassis design
meets the high standards towards quality a nd stability that are
essential for professional applicat ions like digital signage. Despite its
diminuti ve size, the processing power inside the DS77U5 is sufficient to
meet the needs of the most demanding multimedia and computational
workloads. The well-designed interior of the DS77U5 makes installations
and upgrades effortless . Its sleek and stylish loo k blends seamlessly in
both home and office en vironments.
What does Barebone mean?
The Shuttle XPC slim Barebone DS77U5 consists of a stylish metal case
with pre-installed mainboard includ ing processor, cooling s ystem and
external power adapter. Desp ite its small form factor it offers
outstanding connectivity, functionalit y and performance. For a
complete Mini-PC system, a few components still need to be added.
The Mini-PC can be custom ised by installing the following components
i.e. peripherals:
up to two DDR4 SO-DIMM memory modules
(max. 2x 16 GB DDR4-2133)
one 2.5” storage drive (hard disk or SSD)
one SSD card in M.2-2280 form factor (PCI e or SATA)
keyboard, mouse and operating system
Once the desired operation system is installed, the DS77U5 is ready to
use.
Ease of installation thanks to bay covers
The Shuttle XPC slim Barebone DS77U5 features two practical bay
covers at the bottom of the chassis which makes the installation or
upgrade of hardware components a breeze. No cable is required and
no cooling system needs to be installed - setup is quickly compl eted.
24/7 nonstop operation and 0~40°C temperature range
The Shuttle XPC slim Barebone DS77U5 is officially approved for 24/7
permanent operation. Thanks to its low power consumpt ion and
completely passive cooling, this PC runs highly reliably making it
perfectly suitable for digital signage and POI/POS applications – even
at ambient temperatures of up to 40 ° C. [5]
Conditions for permanent use:
- Free circulation of air amongst the PC must be guaranteed
- Ventilation holes must stay clear
- If a hard disk is installed, this must also be approved for permanent
operation by its manufacturer
- For high ambient temperatures higher than 35 °C we strongly
recomm end to use an SSD instead of an HDD.

No fan noise
A large heatsink is con cealed behind a plastic c over and cools down
the processor in a pass ive way without any fan. Using an SSD dri ve
instead of a hard disk makes the system virtually noiseless and hence
perfectly suitable for noise-sensitive environments like e.g. a library,
living room, music stud io or even a b edroom.
Energy-saving
Power consumption mainly depends on system load. Equipped with a
2.5” SSD drive, the system consumes about 7-8 W in idle mode. If the
device is running 5 days a week for eight hours a day in idle mode, the
annual consumption would amount to less than 17 kWh which would
mean just 4~5 Euros on the power bill (25 Euro ct/kWh) - way less than
a conventional desktop PC draws.
Energy-efficient Intel® Kaby Lake-U Processor
The Shuttle XPC slim Barebone DS77U5 is equipped with an Intel® Dual
Core processor of the Kaby Lake-U series which is soldered to
mainboard and passively cooled by a large h eatsink. This ultra low
voltage (ULV) processor belongs t o Intel's s event h-generation Intel Core
processor family (codename: "Kaby Lake") manufa ctured in a new
energy-efficient 14 nm architecture. As a result of further integration, it
comes as a system-on-a-chip (SoC) without the need of an extra
chipset. The integrated Intel HD-Graphics-610/620 engine supports
DirectX 12 and Ultra HD / 4K resolution via DisplayPort 1.2 or HDM I 1.4a.
Great Connectivity
Despite its small size, the Shuttle XPC slim Barebone DS77U5 sports a
wide range of I/O connectors. Bes ides an SD card reader, it comes with
a couple of USB 3.0, USB 2.0, Gigabit -LAN, digital vid eo, audio and
serial ports.
Triple Display with 2x HDMI and DisplayPo rt
The DS77U5 features three digital video outputs: 2 x HDMI and
DisplayPort. This multi -monitoring technology offers multiple display
support on up to three separate monitors. This helps improve on
productivity by allowing for spreading mult iple windows across three
monitors while working with them simultaneo usly.
Note: the DisplayPort of DS77U5 does not support aud io output
Supports 4K Ultra HD at 60Hz
The Shuttle XPC slim Barebone DS77U5 supports displays running at 4K
(3840 x 2160 / 2160p) high resolution at 60 Hz frames per second when
connected to its DisplayPort video output. Being the successor to the
Full HD standard, Ultra HD delivers a four times higher resolut ion with a
wider colour space and colour depth.

Dual Intel Gigabit LAN Network
Today’s media -rich communications across the internet and within
enterprises create new demands for clients in Local Area Networks. For
that reason, Shuttle applies Gigabit L AN performance to this Mini-PC
and the Shutt le XPC slim Bareb one DS77U5 even supports two such
interfaces. Intel network adapters are popular for their excellent
performance and driver compatibility and ar e the preferred choice for
professional environments.
COM ports with plastic caps
RS-232
RS-422
RS-485
RS-232
Two serial ports
Many PCs do not have these legacy ports any longer, since they have
been superseded and replaced by USB for most consumer appli cations, but they are still commonly used for applicati ons such as
industrial automation s ystems, scientific analysis, POS sys tems and other
such fields of application. The Shuttle XPC slim Bareb one DS77U5
features two seria l RS-232 ports which also support both 5 and 12 V
auxiliar y voltage. The left COM port ( COM 1) also supports the RS422
and RS485 standard. The COM ports are prot ected by b lack plastic
caps.
COM port Pin 9 Configuration
Pin 9 of the COM-Port is a multi-functional signal (see red circle on the
photo). Based on the Jumper JP1 configuration on the mainboard, it can
be configured as Ring Indicator (RI) or external power supply with a
voltage level of either 5 V or 12 V (each COM port can be configured
separately).
USB 3.0
The Shuttle XPC slim Barebone DS77U5 has six USB ports, two of which
are USB 3.0. USB 3.0 "SuperSpeed" provides a significant
performance increase over previous USB generations making it the
ideal interface solution for demanding , external peripherals. USB 3.0
supports up to 5Gb/s full duplex which means an up to 10 times greater
performance t han USB 2.0.
M.2-2280-Slot for SSD cards
The M.2-2280 slot supports M.2 SSD storage cards with SATA or with the
more advanced PCIe interface with NVMe support.
Type 2280 means, it supports the usual M.2 cards with a width of 22
mm and a length of 80mm , but also 2242 and 2260 standard cards
are supported .
SD Card Reader
The built-in SD card reader at the front side makes file transfer from
and to a digital camera easy. It takes SD, SDHC and SDXC memory
flash cards in standard size format and also supports booting from
bootable SD cards.

External power button by separate remote line
If space is an object (e.g. in c ase o f a f ixed installation) and the
machine cannot be switched on by pressing the front power button, it
can be powered on by a separate remote line. An appropriate fourpin-connector “SW2” can be found at t he ba ck panel of the Shuttle
XPC slim Barebone DS77U5 (pitch 2.54 mm). In addition, this connector
also provides the Clear CMOS function and an external 5 V DC voltage
supply.
Connect external power button (us e a t empor ary switch)
Close these pins f or 3 seconds to perform a Clear CMOS
External + 5 V DC voltage (Pin 3 = Ground).
Power on after Power fail
The BIOS setup provides a "Power-On after Power Fail" function that can
be found under "Power Management Configuration". As the name
indicates, this fu nction det ermines the PC's behaviour after power
failure: (1) unconditional power on , (2) restore former status, (3) keep
system turned off or (4) PowerOn by LAN. As a matter of the nature of
this function , it may fail after short power failures. This is why the DS77U5
also comes with a hardware-based solution. By r emoving Jumper J9
(see qui ck guide) the system will start unconditionally once power is
applied.
Kensington Lock
This is a small, metal-reinforced hole as part of an anti-theft syst em. The
Shuttle XPC s lim Barebone DS77U5 provides an appropr iate hole on
both sides of its chassis . The lock-and-cable is not included.
VESA mount
The supplied 75/100mm VESA mount allows the S huttle XPC slim
Barebone DS77 U5 to be wall-mounted or just to be affixed on the rear
side of a monitor which is particularly inter esting for the industry
segment, company buildings and public institutions. B esides, the
chassis of the Shuttle XPC s lim Bareb one DS77U5 provides numerous
threaded holes (M3) enabling it to be fitted almost anywhere.
Supplied accessory: VESA mount with screws

The DisplayPort output can be con verted to HDMI or DVI by an additional, passive adapter cable. For example:
DELOCK 82590: 1m, DisplayPort (male, 20p) to HDMI -A (male, 19p)
DELOCK 82435: 5m, DisplayPort (male, 20p) to DVI-D (male, 24p)
The integrated graphics automatically detects the connected display and puts out the appropriate electric signal either DisplayPort (without an adapter) or HDMI/DVI (with an adapter).
However, a monitor with a DisplayPort connector cannot be connected to t he HDMI port with a simple, passive
adapter.
