1. CONNECTING KEYBOARD + MOUSE

Normal operation of Tango does not require a keyboard or mouse to be

connected. However, most debug operations on Tango will require a keyboard

and mouse to allow access to Windows components such as Windows Explorer

or the control panel. Use a USB keyboard and mouse and connect these devices

to the rear USB ports on Tango as shown below.

Note: The motherboard in Tango is a lower power design and does not

support high power USB devices. You will likely experience problems trying

to connect USB powered devices such as KVM boxes, USB hubs, illuminated

keyboards, etc.

2. TANGO SOFTWARE SHUTDOWN

While most debugging/configuring of the console can be performed while the

Tango software is operating, it may be necessary to close the software to perform

some operations. The following steps outline how to close the console software

applications without shutting down the entire console (as would be the case if

you used the SHUTDOWN command in Tango).

• Press Alt + Tab until the “Smart AV Console Monitor” application is

active.

• Click on the “Kill All” button to close all the Tango applications.

• De-select the “Hide Taskbar” checkbox so that the taskbar is displayed.

• Minimize the Console Monitor window by clicking on the Minimize

button.

3. GRAPHICS PROPERTIES

Graphics problems with the console can be divided into 2 categories, hardware

problems or driver / configuration problems. When the console first boots, the

BIOS will display the message “Console Starting. Please Wait……..” in a

diamond shape. If you can see this message clearly then the display hardware is

most likely OK and you should proceed through this section to resolve a graphics

driver properties problem. If the display is blank, fuzzy or a series of striped

lines during this stage of bootup you need to check the hardware (see section 11).

If the boot message is displayed correctly but then the screen is blank (white) or a

series of horizontal or vertical lines, try pressing CNTRL + ALT + F3 on your

keyboard and wait a few seconds. If the display does not return you will need to

open the upper module of the console and connect a VGA monitor directly to the

motherboard to diagnose the graphics driver properties.

The graphics card in Tango is integrated into the motherboard within the

console. This graphics card is configured to drive 2 displays within Tango, the

main 22” LCD (driven directly via LVDS – like in a notebook PC) and an optional

external DVI LCD (used for the passive extension bay). The connector for this is

on the rear of the console. There is also a VGA output on the motherboard (only

accessible within the console) which may be useful for debug purposes.

Resolving any display problems with Tango should start with a check of the

graphics driver properties / settings.

• On the keyboard, press the “Windows” key and then select “Control

Panel” from the start menu.

• From the control panel, select “Intel Extreme Graphics”

• In the graphics driver window, click on the “Display Devices” tab and

check the settings are as shown below. The secondary device is the

external DVI for the extension bay and should be set to “Digital Display”.

You will only be able to select this setting if you have a DVI monitor

selected. If you don’t you can simply leave it set to “Monitor” as shown

below. You will need to revisit this setting if you connect an extension bay

in the future.

NOTE: The primary device must always be set to Notebook. If it is

incorrectly changed the display will go blank when you click Apply and

problems could arise.

• If you need to change any settings click on the “Apply” button when you

are done and then click “OK” to confirm the new settings. If you make a

mistake and the display goes blank or to an unsupported resolution where

you can’t see anything, don’t click “OK” to confirm and it will revert to the

original settings after 15 seconds so please wait.

• Now click on the “Display Settings” tab and then “Notebook” and check

the settings are as shown below, particularly the resolution and rotation.

14th Oct 2009 7

• If you need to change any settings click on the “Apply” button when you

are done and then click “OK” to confirm the new settings. Again, if you

make a mistake and the display goes blank or to an unsupported

resolution where you can’t see anything, don’t click “OK” to confirm and

it will revert to the original settings after 15 seconds so please wait.

• If you have an extension bay connected to the DVI output, click the other

tab and make sure the settings for this display are the same.

NOTE: If the display on your console is blank (as a result of incorrect

adjustments or for some other reason) you should try pressing CNTRL + ALT

+ F3 on your keyboard and wait a few seconds. The monitor should come

back on and then you can proceed through these steps again with the correct

settings. This key press switches the Primary Monitor back to Notepad. If

this fails you will need to open the console and connect a VGA monitor to

proceed.

At this point you display should be functioning correctly again. If you were

unable to select the correct resolution (1680 X 1050) in the steps above you need

to check the following Windows settings.

• On the keyboard, press the “Windows” key and then select “Control

Panel” from the start menu.

• From the control panel, select “Display”.

• Select the “Settings” tab and click the “Advanced” button.

• Select the “Monitor” tab and make sure the checkbox labelled “Hide

Modes That This Monitor Cannot Display” is unchecked.

4. TOUCHSCREEN DRIVER

If the touch screen fails to function the first step is to check the driver and

associated settings. Firstly check the driver is correctly enabled (a reboot of the

console may also fix a problem here).

• On the keyboard, press the “Windows” key and then select “Control

Panel” from the start menu.

• From the control panel select “System” and then select the “Hardware”

tab.

UNCHECK

IMPORTANT: Before proceeding with any touchscreen repairs

you should ensure the display is thoroughly cleaned as per the

notes in the installation guide. This must include cleaning around

the bezel area using compressed air. Dust in this bezel area is a

common cause of touchscreen failures.

USB Interface 6001u Rev 1”. Make sure there is not a red cross or yellow

“!” displayed on this device (either would indicate a problem).

• If there is a problem with this device, right click (on the device) and select

“Disable” from the menu.

• Wait 5 seconds and then right click and select “Enable” from the menu.

This will have re-started the driver.

If this device does not exist in the list or you have not been able to resolve your

problem using the above steps, you most likely have a hardware problem or the

driver has been un-installed or corrupted. You will need to go to the hardware

section of this manual and check all the touchscreen connections and/or re-

install the touchscreen driver. If you are unable to re-install the driver, check for

a hardware problem (see section 12).

Once you download the touchscreen driver from the Smart AV website, install it

as follows:-

• Insert your USB stick containing the driver files (unzipped) into the upper

USB port on the rear of the console (beside the power switch).

• Click on the “Start” menu and select “Run” to open the “Run” window.

6. CONSOLE BIOS

NOTE: Any changes to BIOS settings can be dangerous and may render the

console un-useable. Incorrect display selection in the BIOS will disable the

console LCD and will require considerable disassembly of the console.

The BIOS settings of the console should not require any changes by the user or

during servicing. The selected settings are the default that will remain, even if

the BIOS battery goes flat.

The BIOS start-up messages are hidden from the user and a simple message

stating “Console Starting. Please Wait…..” is all that is displayed.

If this “Console Starting. Please Wait…..” message is not displayed or the screen

displays a funny pattern or series of lines during boot then there could be a

problem with the BIOS settings (if you suspect they have changed – otherwise

check the display hardware first). You will need to disassemble the console to

access the VGA port inside and then see section 11 for the correct BIOS settings.

7. OPENING THE CONSOLE – UPPER MODULE

The console upper module can be opened for servicing by following the steps

below. Care must be taken to ensure no damage is done to the black painted

surfaces or the acrylic lens material on the top surfaces. Both of these can be

easily scratched if not handled carefully.

• Ensure the console is powered off and all external connections are

removed from the console.

• Remove the aluminium end panels from both sides of the console. This is

done by removing the 6 x M6 CSK screws that secure each end panel.

These screws require a 2.5mm Allen Key for removing them. The location

of these screws is shown below.

WARNING:

The chassis of the Tango console has some flexibility when the top

modules are removed. You must service the console on a flat work

surface and take precautions to ensure the chassis is not excessively

twisted or stressed while disassembled. Failure to take these

precautions could result in damage to some of the internal

components.

• Remove the 3 x M3 screws from each side of the upper module (see

below).

• Carefully open the upper module from the bottom edge. The best

approach is to hinge the module open like a car bonnet.

NOTE: Take extra care with this step so that the acrylic lenses are not

damaged at the point where the 2 modules meet. The best way is to slide the

module upwards first and then lift the bottom edge once it is clear of the lower

module.

You now have access to all the major components inside the console. You may

be able to services some components by having an assistant hold the upper

module open while you work within the console. If you wish to remove the

module completely, proceed as follows, taking careful note of the various

connections as this will help with re-assembly.

• Remove the LVDS cable from the monitor. You will need to cut the cable

tie that is securing this cable.

• Remove the Inverter cable from the inverter PCB.

• Remove the Touch Screen cable from the touch controller module.

• Disconnect the upper USB cable.

• Remove Power Switch cable by disconnecting the spade terminals from

the main power switch.

• Lift the upper module clear of the console.

To re-assemble the upper module into the console, proceed as follows.

• Re-connect all 5 cables. Note there is no polarity for the Power Switch

cable and that the metallic surface of the LVDS connector should be facing

the LCD monitor (the polarity of this connection is difficult to see).

• Carefully lift the upper module back into position.
