1.5. USB Subsystem
1.5.1. General
USB is standard serial bus for connecting peripherals to your PC. USB is the key to true Plug and
Play capabilities of your PC.
- USB enables you to attach and detach new peripherals while your PC is running.
- You don’t have to wonder about which port of the PC you should use when plugging in a
peripheral. since all four---pin USB connectors accept any USB peripheral to be connected, there
isnowaytodoitwrong.
- Also the need for configuring and booting in adding or removing new peripherals disappears.
USB itself detects and configures peripherals as soon as they are attached or deattached.
- It allows your system to grow in response to your needs without extra costs. In theory USB
supports up to 127 devices.
- USB has a wide industry support among leading computer, telecommunications, electronics and
software companies.
USB requires one host in any USB system: it is normally the PC. Only one USB device has to be in
direct connection to the PC and the others can be connected through USB hubs. Each hub has
downstream ports for attaching peripherals and one upstream port for connection towards the host.
The picture below illustrates the USB system.
HUB HUB HOST
Keyboard Monitor PC
Mouse Speaker Micro--

1 Upstream port
USB has two data bandwidths, which can be in use simultaneously:
- The high-speed bandwidth (12Mbps) supports multimedia and telephony devices
- The low-speed bandwidth (1.5Mbps) is dedicated for low-end devices like keyboards and mice
USB enables transferring compressed video for teleconferences, but it cannot handle moving video
with high resolution.
USB devices can be divided into two categories, namely bus-powered and self-powered devices:
- Self-powered devices take their power from the mains supply
- Bus-powered devices rely on the power supplied by the USB cable. In the picture before low-
power devices like keyboard and mouse can be called as, low power, bus-powered devices (3
100 mA)
Each USB cable segment provides +5 volts of power. The maximum length of USB cable segment
is 5 meters.
The host in the system is responsible for allocating USB bandwidth for transferring information. Data
transfer over the USB cable starts with synchronization information. This information is called the
Token Packet. It includes information about the type and the direction of the transfer, USB device
address and an endpoint number. After that follows the actual Data Packet or control information.
The destination of the transfer answers with a Handshake Packet as a mark of a successful transfer.
USB error rate is very low, but in case of an error USB hardware will retry sending three times before
informing the software about the error
In addition the host (or the PC) detects the attachment or removal of any USB device. All USB de-
vices are attached to the USB through hubs. They indicate the removal or attachment of a USB de-
vice in their port status.
After that the host of the system enables the port and defines a unique USB address for the device.
In case of a device removal the hub disables the port and gives an indication of device detachment
tothehost.Iftheaddedorremoveddeviceisahubtheaboveproceduremustbeperformedforall
the attached peripherals.

1.5.2. Bus powered connections
Low power: All power to these devices comes from USB connector. They may draw no more than
one unit load (100 mA)at any time.
High power: All power to these devices comes from USB connector. They must draw no more than
one unit load upon power up and may draw up to five unit loads after being configured.
1.5.3. Universal Serial Bus Hub
The USB provides Plug and Play capabilities for peripherals. The bus physical interconnection is a
tiered star topology. USB system provides hub for four downstream devides.
1.5.4. USB ports
Unit is capable to handle 4 connected downstream USB devides from the HUB. There are so 4 pcs
serie A and one piece serie B for upstream (root) connectors in the rear of the monitor. These can
be used for any PC based application as keyboard, mouse, printer, scanner, modem, etc.

1.5.5. USB connectors
The data is transferred differentially meaning low radiation. The driver delivers initially ≥2V swing to
the cable of Z0=90τ±15%. Data signal rise time is 4 nsmin and 20 nsmax. A d d --- o n j i t t e r f r o m
driver is < 3 ns. Maximum cable length is 5 m.
The differential receiver sensitivity is at least 200 mv. Maximum allowed jitter is 25 ns.
The port supplies 4,75V --- 5,25V having current up to 0.5 A to the peripherals. Combined 3 port cur-
rent limitation is provided for safety reasons. Current of the 0.5 mA is taken in suspend mode and
starting current of 0.1 A is quaranteed.

1.6. Monitor Connection
Make sure that the monitor is disconnected from mains and the power switches of
the computer and all attached devices are turned off before connecting the monitor.
- Connect the signal cable plug to the videocontroller connector at the back of the computer.
- Tighten the screws on the plug by hand.
- Connect the power cord first to the monitor and then to a grounded power outlet.
1.4.1. If your monitor is DDC compatible (PC)
- Do not use any adapter when connecting signal cable to your computer.
- Do not extend the signal cable with extension lead. The DDC signals will not accept extended
cable.
1.4.2. If there is no DDC in your computer (PC)
- Normally there is no need for adaptor when connecting signal cable to your computer.
- Use MAC adaptor in signal cable when connecting the monitor to an Apple
Macintosh computer.
- If the computer is equipped with separate display adapter card. It may have a standard
D---SUB connector. In that case MAC adaptor is not needed.

When the power is turned on, the power-- on indicator will light.
The colour of the the power---on light indicates the operating state of the monitor.
- Green: The monitor is in normal operation or stand ---by state.
- Blinking Green: The monitor is in automatic suspend or power off state.
- Not illuminated: The monitor is turned off with power switch or disconnected from mains outlet.
If the power management function working properly in your computer, you do not need to switch the
monitor on or off. It happens automatically.
The power switch does not disconnect the
monitor from mains. In oder to make the monitor
completely powerless, unplug the power cord

2. Site Preparation
2.1. Location
This Monitor is designed for normal office conditions. It is equipped with own power supply. It is not
to be serviced or repaired on site
2.2. Troubleshooting
Local service facilities should perform simple maintenance such as trimming. More advanced main-
tenance and repair that requires replacement of components which in turn requires testing and re-
trimming should be carried out in a central workshop.

fects If colour defect is repeated without the monitor having been moved, it is possible
that the monitor is influenced by a strong magnetic interference field (near to
a high power cable, for example). Try to find a better location for the monitor or
the interference source. Note that another monitor placed too near (less than
30 cm.) may also generate interference in the picture.

Open the Miscellaneous/Selftest menu. Check the color of the Red, Green and
Blue bars. If they have pure colors, the fault is not in the monitor. Check signal
cable connectors and the computer. If the menu itself and the color bars are
discolored, the monitor is obviously damaged.

3. Controlling the Memory for Picture Adjustments
Thepictureadjustmentvaluesarestoredinnon-volatilememory.Thememoryhasseparatedareas
for User Adjustments and for Factory Adjustments.
3.1. Memory for User Adjustments
3.1.1. Adjustment
1If there are values available in the memory for user adjustments, corresponding to the present
timing signals, they are always used.
2New user made adjustments are stored to the memory for user adjustments.
3.1.2. Resetting the User made settings
3User memory can be emptied from user made settings. Resetting affects only the timing
which is currently active. The reset function is inhibited if no corresponding factory preset dis-
play mode exists.
After resetting all picture properties are coming from memory for factory adjustments.
3.2. Memory for Factory Adjustments
3.2.1. Adjustment
4Factory adjustments can be updated with service menu in service mode. If there is no location in
factory adjustment memory for timings currently in use, the adjustment affects the memory for
user adjustments.
- If the memory location mentioned in case 1is empty, the picture adjustment values are read
from memory for factory adjustments. Factory adjustments, corresponding to the current tim-
ings, are transferred to user memory if any picture property is adjusted. After that the operation
is as in case 1.
