9. BIOS Settings

9.1 General Information

The ITX-N-3800 includes a uEFI BIOS from Phoenix Technologies 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 poweroff). When power is applied to the system, the ITX-N-3800 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 F2. This key (F2) must be pressed when either the splash screen is displayed (during the system power-on self test, POST) or when the Press F2 for Setup message is displayed. It may take a few seconds before the main setup menu screen is displayed.

ITX-N-3800/BIOS Settings

Press F2 to enter SETUP

If the message disappears before responding and you still wish to enter Setup, restart the system by pressing the RESET button. It can be also restarted by pressing the Ctrl,

Alt, and Delete keys on the keyboard simultaneously.

Press <F1> to Run General Help or Resume

The BIOS setup program provides a General Help screen. The menu can be easily called up from any menu by pressing F1. The Help screen lists all the possible keys to use and the selections for the highlighted item. Press Esc to exit the Help screen.

1. Remove power from the ITX-N-3800.

2. Find JP7/JP8.

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 41

10.1.3 Update BIOS

1. Obtain the ROM file and flash utility. See “Cables and Software Drivers” on page 43.

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-3800 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 F2 to open the BIOS setup menu and select Load Setup Defaults.

9. To finish the update, select the Exit Saving Changes option.

ITX-N-3800/Troubleshooting

10.1.4 Install USB 3.0 Windows 7 Driver

The ITX-N-3800 uses the Bay Trail platform. This platform requires the following configuration to be able to use the USB 3.0 driver needed for the Windows 7 Operating System (OS). Perform this procedure before installing Windows 7.

NOTE Windows 8 can use the USB 3.0 driver directly; this procedure is for Windows 7.

1. Restart the computer and then press the F2 key to open the BIOS setup menu.

2. From the Advanced tab on the USB Configuration screen:

– Set XCHCI Mode to [Disable]

Appendix A. Best Practices

This section outlines the best practices for operating the ITX-N-3800 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-3800/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-3800.

Use Proper Power Connections (Voltage)—When verifying the voltage, measure it at the power connector on the ITX-N-3800. Measuring it at the power supply does not account for voltage drop through the wire and connectors. Power the ITX-N-3800 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-3800.

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 44

ITX-N-3800/Best Practices

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-3800 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 (http://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.
