IRQ 5 is use d b y System Refer to item 4-2)

When you service the units in the field, take special care not to install the combination of an old Main PWB and a new VGA PWB or a new Main PWB and an old VGA PWB. Please modify Main PWB’s in the following methods:

To modify Main PWB’s from old to new, please refer to item 5-1) please refer to item 5-1) How to modify old Main PWB’s to new Main PWB’s. With this modification implemented, old Main PWB’s function as new Main PWB’s.

To modify Main PWB’s from new to old, please refer to item 5-2) How to modify new Main PWB’s to old Main PWB’s With this modification implemented, new Main PWB’s function as old Main PWB’s.

Important: The old VGA PWB’s cannot be modified to the new VGA PWB’s, or vice ve rsa.

Refer to items 2 and 3-1). Refer to item 3-2).

2) IRQ signal compatibility

The old Graphics Controller does not use an IRQ, while the new Graphics Controller uses IRQ5. To avoid IRQ collisions, Please assign IRQ’s other than IRQ5 to the other devices. The following chart shows IRQ’s available to optional devices.

ISA PC board can built in UP-5350 up to two. 5V PCI board can built in UP -5 350 instead of an ISA PC bo ard . This has to satisfy the power consum pti on .

3-6. SHUTDOWN SWITCH

The shutdown switch is used when the OS or applica tion programs are straying and the system can not return to the normal state.

You must not use this sh utdown s witch whe n the UP- 5350 is r unning normall y. Use th is swit ch only wh en the mai n power sour ce is n ot cut off even if the main unit power switch is set to OFF position. The UP-5350 is turned OFF and the hardware is reset by turning the main power switch OFF and th en pressing the shutdown sw itch .

12345678

Shut down switch

[OUT LINE]

The shutdown switch is a si ng le shu t type . (Normally OFF position) Push ON: This position is used to reset the stand-by mode for

power supply unit during softw are hang ups.

Release OFF: Usually the shutdown switch needs to be set to this

position when the UP-5350 is operating.

[OPERATING METHOD]

The shutdown switch is a push switch. If it is pushed to ON, the UP-5350 stops supplying the power when the power switch is set into stand-by mode.

NOTE:The shutdown operation will be ignored when the power switch

is set to power-on position.

Power switch :

[OUT LINE]

The power switch has the positions ON and OFF (Stand-by) ON position: Usually the power switch needs to be set to this posi-

tion when the POS-terminal is operated .

OFF position: This position can be used to for the stand-by mode.

When the power switch is set to this position, the power supply stops automatically. But if the software program co ntrols the power supply t o hold, ev en if the power switch is set into this position, the power supply will stay on until the software program allows a power supply to turn OFF.

[OPERATING METHOD]

The power switch is a see-saw switch, and it can be tipped toward the ON or OFF position.

2. CAUTIONS ON HANDLING CPU AND POWER FAN

When removing or performing maintenance activities on the CPU and POWER FAN, be sure to handle them with care, because it may cause abnormal sounds or deteriorate th eir performance if th ey are dropped or exposed to a heavy impact.

3. NOTE FOR HANDLING OF TOUCH PANEL

• The transparency of the touch panel should be vitally important.

Use clean gloves and masks.

• For handling, do not hold the transparent area, and do not hold the

heat seal connector section to assure reliability.

• Do n ot o verl ay to uch panels. The edge ma y damage the surface.

• Do not place heavy things on the touch panel.

• Do not apply a strong shock, and do not drop it.

• When attaching the protection film again, carefully check for dirt. If

there is any dirt, it is transferred.

• To clean dirt on the surface, use a dry, soft cloth or a cloth im-

mersed in ethyl alcohol.

• Check that the housing does not give stress to the touch panel.

• Be care ful no t to to uch the touch panel with tools.

• Th e he at sea l se ctio n is easily disconnected. Be carefu l not to pl ace

stress to the heat seal section wh en installing.

• The touch panel is provided with an air groove to make the external

and the internal air pressure equal to each other. If water or oil is put around the air groove, it may penetrate inside. Be careful to keep the air groove away from water and oil.

• Do n ot u se sharp objects when making in pu t entrees.

4. NOTE FOR HANDLING OF LCD

• The LCD elements are made of glass. BE careful not to expose

them to strong mechanical shock, or they may be broken. Use extreme care not to break them.

• If the LCD element is broken and the liquid leaks, avoid contact with

your mouth or eyes . If th e liq uid co mes in c ontac t with y our s kin or clothes, immediately clean w ith soap.

• Use the unit under the rated conditions to prevent against damage.

• Be careful not to place water or o the r liquids on the display surface.

• The reflection plat e and the polarizing pl ate are easily scra tched.

BE careful not to touch them with a hard object such as glass, tweezers etc. Never hit, push, or rub the surface with hard objects.

• When installing the unit, be careful not to apply stress to the LCD

module. If excessive stress is applied, abnormal display or uneven color may result.
