9.1 General Information
The ITX-N-3900 includes a BIOS from AMI stored in Flash ROM. Access setup
information through the BIOS setup utility to modify basic system configuration. The
configuration is stored in CMOS RAM (it is retained during power-off). When power is
applied to the system, the ITX-N-3900 communicates with peripheral devices and
checks hardware resources against the configuration information stored in the CMOS
memory. If during startup an error is detected or the CMOS parameters need to be
initially defined, the diagnostic program prompts the user to enter the SETUP program.
Some errors are significant enough to cause the startup to fail.
9.2 Entering Setup
To enter setup, apply power to the computer and then press the DELETE key or the ESC
key. Either of these keys must be pressed when either the splash screen is displayed
(during the system power-on self test, POST) or when the following prompt message is
displayed. It may take a few seconds before the main setup menu screen is displayed.

10. Troubleshooting
This section provides useful tips to get the ITX-N-3900 operating. For basic hardware
installation and configuration, refer to “Installation and Connections” on page 7. This
section addresses system integration issues in terms of BIOS setting and OS
diagnostics.
10.1 BIOS Settings
This section assumes that you have correctly selected and connected all the devices
with the required cables before applying power. If this is in question, inspect the
connection and application of each of the following components: 204-pin DDR3
Memory, keyboard, mouse, SATA hard disk, VGA connector, power cable of the device,
and all ATX accessories. Failure of any of these components can cause system failure.
It is recommended that you press the DELETE or ESC key and enter the BIOS setup
menu during the initial boot-up sequence to configure a stable BIOS configuration that
can be woken.
ITX-N-3900/Troubleshooting
10.1.1 Loading the Default Optimal Settings
NOTE If the system appears to be unstable during its startup, you can try loading the default
BIOS configuration to see if this solves the issues.
When prompted in the main setup menu, load setup defaults:
1. Apply power to an installed ITX-N-3900 and press the DELETE or ESC key to enter
the BIOS setup menu.
2. Select the Save & Exit menu and then scroll to Restore Defaults.
3. Press Enter.
4. To load the default optimal BIOS setup, select Yes. This forces the BIOS setting
back to the initial factory configuration.
10.1.2 Reset CMOS BIOS Configuration
Jumpers can be used to reset the BIOS CMOS settings to the factory default. Enable/
disable the Clear CMOS Function hardware circuit, by placing or removing the jumper
from JP3 as needed (see “CMOS Clear (JP3)” on page 23).
To reset the BIOS CMOS configuration to the factory default settings:
1. Remove power from the ITX-N-3900.
2. Find JP3.
3. Remove jumpers from pins 1-2.
4. Install jumpers on pins 2-3 and wait five seconds.
5. Replace jumpers back on pins 1-2.
v1.0 www.winsystems.com Page 54
10.1.3 Update BIOS
1. Obtain the ROM file and flash utility. See “Cables and Software Drivers” on page 55.
2. Extract the files from the zip archive to the root directory of a bootable USB flash
drive. The three required files are: Shell Flash 32.efi, temp.bin, and Update.nsh.
3. Insert the USB flash drive in USB port of the ITX-N-3900 and apply power to the
board.
4. Boot to EFI-Shell mode.
5. At the prompt, enter the command fs0: to change to the root directory of the USB
drive.
6. At the root directory of the USB drive, enter the command update to start the
updating the BIOS.
7. When the update has completed, there will be a 5-second pause and then the
computer automatically restarts.
8. Press the DELETE or ESC key to open the BIOS setup menu and select Restore
Defaults.
9. To finish the update, select the Save & Exit option.

Appendix A. Best Practices
This section outlines the best practices for operating the ITX-N-3900 in a safe and
effective manner that does not damage the board. Please read this section carefully.
Avoid Electrostatic Discharge (ESD)—Only handle the circuit board and other bare
electronics when electrostatic discharge (ESD) protection is in place. Having a wrist
strap and a fully grounded workstation is the minimum ESD protection required
before the ESD seal on the product bag is broken.
Power Supply
Power Supply Budget
Evaluate your power supply budget. It is usually good practice to budget twice the
typical power requirement for all of your devices.
Zero-Load Power Supply
ITX-N-3900/Best Practices
Use a zero-load power supply whenever possible. A zero-load power supply does not
require a minimum power load to regulate. If a zero-load power supply is not
appropriate for your application, then verify that the single board computer’s typical
load is not lower than the power supply’s minimum load. If the single board computer
does not draw enough power to meet the power supply’s minimum load, then the power
supply will not regulate properly and can cause damage to the ITX-N-3900.
Use Proper Power Connections (Voltage)—When verifying the voltage, measure it
at the power connector on the ITX-N-3900. Measuring it at the power supply does
not account for voltage drop through the wire and connectors.
Power the ITX-N-3900 using J1 (+12 V DC) or J12 (ATX 4-pin connector). Verify the
power connections. Incorrect voltages can cause catastrophic damage.
Power Harness
Minimize the length of the power harness. This will reduce the amount of voltage drop
between the power supply and the ITX-N-3900.
Gauge Wire
Use the largest gauge wire available for your application and connector. Most connector
manufacturers have a maximum gauge wire they recommend for their pins.
Contact Points
For maximum reliability, WinSystems boards typically use connectors with gold finish
contacts. It is critical that the contact material in the mating connectors is matched
properly (gold to gold and tin to tin). Contact areas made with dissimilar metals can
cause oxidation/corrosion, resulting in unreliable connections.
v1.0 www.winsystems.com Page 56
ITX-N-3900/Best Practices
Pin Contacts
Often the pin contacts used in cabling are not given enough attention. The ideal choice
for a pin contact uses a design similar to Molex’s or Trifurcon’s design that provides
three distinct points to maximize the contact area and improve connection integrity in
high shock and vibration applications.
Power Down
Make sure that power has been removed from the system before making or breaking
any connections.
Power Supply OFF—The power supply should always be off before it is connected to
the I/O Module. Do not hot-plug the ITX-N-3900 on a host platform that is already
powered.
I/O Connections OFF—I/O Connections should also be off before connecting them to
the embedded computer modules or any I/O cards. Connecting hot signals can cause
damage whether the embedded system is powered or not.
Conformal Coating
Applying conformal coating to a WinSystems product will not in itself void the product
warranty, if it is properly removed prior to return. Coating may change thermal
characteristics and impedes our ability to test, diagnose, and repair products. Any
coated product sent to WinSystems for repair will be returned at customer expense and
no service will be performed.
Operations/Product Manuals
Every single board computer has an Operations manual or Product manual.
Periodic Updates—Operations/Product manuals are updated often. Periodically check
the WinSystems website (https://www.winsystems.com
Check Pinouts—Always check the pinout and connector locations in the manual before
plugging in a cable. Many I/O modules will have identical headers for different functions
and plugging a cable into the wrong header can have disastrous results.
Contact an Applications Engineer—If a diagram or chart in a manual does not seem to
match your board, or if you have additional questions, contact a WinSystems
Applications Engineer at: +1-817-274-7553.

licensed hereunder which have been developed or manufactured by WinSystems shall be free of any defects and shall perform
substantially in accordance with WinSystems' specifications therefor. With respect to any Products or Software purchased or
licensed hereunder which have been developed or manufactured by others, WinSystems shall transfer and assign to Customer
any warranty of such manufacturer or developer held by WinSystems, provided that the warranty, if any, may be assigned. The
sole obligation of WinSystems for any breach of warranty contained herein shall be, at its option, either (i) to repair or replace at
its expense any materially defective Products or Software, or (ii) to take back such Products and Software and refund the
Customer the purchase price and any license fees paid for the same. Customer shall pay all freight, duty, broker's fees,
insurance, charges and other fees and charges for the return of any Products or Software to WinSystems under this warranty.
WinSystems shall pay freight and insurance charges for any repaired or replaced Products or Software thereafter delivered to
Customer within the United States. All fees and costs for shipment outside of the United States shall be paid by Customer. The
foregoing warranty shall not apply to any Products or Software which have been subject to abuse, misuse, vandalism, accident,
alteration, neglect, unauthorized repair or improper installation.
THERE ARE NO WARRANTIES BY WINSYSTEMS EXCEPT AS STATED HEREIN. THERE ARE NO OTHER WARRANTIES EXPRESS
OR IMPLIED INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. IN NO EVENT SHALL WINSYSTEMS BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL OR SPECIAL
DAMAGES FOR LOSS OF DATA, PROFITS OR GOODWILL. WINSYSTEMS' MAXIMUM LIABILITY FOR ANY BREACH OF THIS
AGREEMENT OR OTHER CLAIM RELATED TO ANY PRODUCTS, SOFTWARE, OR THE SUBJECT MATTER HEREOF, SHALL NOT
EXCEED THE PURCHASE PRICE OR LICENSE FEE PAID BY CUSTOMER TO WINSYSTEMS FOR THE PRODUCTS OR SOFTWARE
OR PORTION THEREOF TO WHICH SUCH BREACH OR CLAIM PERTAINS.
Title to the Products shall remain vested in WinSystems until complete payment is made by Customer. Title to any Software shall

during and after the term of the License. Nonpayment when due of the purchase price for any Products or the License fees for
any Software, or, if applicable, taxes and/or the cost of any freight and insurance for any Products and/or Software, shall entitle
WinSystems to take possession of the Products and/or Software without notice to Customer or prejudice to WinSystems' rights
under contract or any other legal remedy.
Until title to the Products pass in accordance with the provision set out above, except with the prior written approval of
WinSystems, no Products shall be modified, altered, moved or in any way assigned, sublet, mortgaged or charged nor may
Customer part with possession of all or part of the same.
There are no understandings, agreements or representations, express or implied, other than those set forth herein. This Order
embodies the entire agreement between the parties and may be waived, amended or supplemented only by a written instrument
executed jointly by WinSystems and Customer as evidenced only by the signature of duly authorized officers of each party. The
foregoing terms and conditions of any order which may be issued by Customer for the purchase of Products or licensing of
Software hereunder.
In the event this Order is placed in the hands of an attorney or collection agency by WinSystems to collect any sums due
hereunder to WinSystems, Customer shall pay all reasonable attorney's fees, expenses, collection and court costs incurred by
WinSystems.
THIS AGREEMENT SHALL BE GOVERNED AND CONSTRUED UNDER THE TEXAS UNIFORM COMMERCIAL CODE AND THE
APPLICABLE LAWS OF THE STATE OF TEXAS. THE PARTIES ACKNOWLEDGE THAT ANY ACTION BROUGHT HEREUNDER
SHALL ONLY BE BROUGHT IN A COURT OF COMPETENT JURISDICTION IN TARRANT COUNTY, TEXAS.
