before you switch the device off. This allows the drive to come to a
complete stop and ensures optimal protection.

3. Unplug all the connecting cables.

4. Close the covers protecting the ports and connections on the right-hand
and left-hand side panels.

5. Bring the unit into an upright position.

6. Raise the keyboard and lock it by pressing it against the front panel of the
unit. The latches on the right and left snap in. Make sure that both catches
are properly locked.

7. If you only want to carry the unit for a short distance, use the handle.

8. If you want to move the PG 720 over larger distances, pack the unit and
all its accessories in the carrying bag supplied.

Depending on the gray tone or color shade in the display, passive STN
displays are subject to varying degrees of interference known as the Moiré
effect. This is a physical characteristic and is not a fault.

Caution

!

Risk of injury!
If a display is damaged, liquid crystals may escape. Do not touch this liquid

or allow it to come into contact with your skin in any way, and do not breath
in the vapors. If you do come into contact with the liquid, wash those parts
of the skin affected immediately with alcohol, and rinse with plenty of water.
Then consult a physician immediately.

Use only a cotton cloth and a neutral cleansing agent to clean the display. Do
not use water or aggressive solvents (such as alcohol or acetone). Never
touch the display with hard, sharp objects. Avoid exerting any pressure on
the display surface.

Figure 3-13 External Power Supply Unit

Caution

Danger of overheating!
The external power supply unit can be damaged if it is covered.

Battery

The PG 720 has an integrated NiMH (nickel metal hydride) rechargeable
battery . This makes the device portable, meaning you can use it without the
external power supply. The battery also prevents data loss occurring on
power failure.

Once the external power supply unit is connected, the battery is charged. The
following conditions are important:

 When charging, the battery temperature must be between + 5° C and

+ 40° C (40° F and 100° F).

 When the device is switched off, charging takes approximately 2 hours

(fast charging).

 When the device is switched on, charging takes approximately 6 hours

(reduced charging current).

 Charging stops as soon as the battery is fully charged.
 In storage, a fully charged battery runs down in approximately 2 months.

It must then be recharged.

4.2 Battery Operation

Installing and Operating the PG 720

Battery Operation

If no external power supply unit is connected, you can operate the PG 720
using the integrated battery.

1. Switch on the device. Make sure that the battery is sufficiently charged
before you start work. The power LED is lit green as long as the battery is
sufficiently charged.

2. Work as normal with your PG 720.

3. As soon as the power LED lights up red in battery operation, this
indicates that the battery is almost run down. Stop working and save your
data.

Note

You should only begin working in the battery mode when the battery is
completely charged. Only then can you be sure that the full operating time is
available and that the battery running down will be indicated in good time. The
battery is fully charged when the power LED changes from charging (orange)
to charged (green) after switching on with the unit connected to the mains power
supply .

When you first start up, the battery may be partly or completely discharged (for
example, self-discharge). Connect the programming device to the power supply
using the power supply unit to charge the battery.

As soon as the device is connected to the external power supply, the connected
battery will be immediately recharged if it has been discharged. If the device
is switched off, this will take approximately 2 hours (fast charging); if the device
is switched on, the charging will take approximately 6 hours with reduced
charging current.

Interfaces with
Line Current
(TTY, 20 mA)

Rules

In this section, you will learn how to connect your PG 720 to a programming
device or S5 programmable logic controller using a point-to-point
connection.

You can establish a point-to-point connection by connecting the PG 720 to
another programming device or a programmable logic controller using

 An RS-232 connection
 A TTY connection

T o ensure reliable data transfer, several factors must be taken into account.

You can reduce interference by choosing the right transmission cable and
connecting it properly, and by observing the following guidelines:

 Use a shielded cable with a low line resistance (130  / km) (about 40 

kft) and low capacitance (< 90 pF/m) (about 27 pF/ft). Twisted-pair cables
are less susceptible to noise and interference. A low line resistance results
in reduced voltage excursions and shorter charge reversal times. The line
resistance decreases with increasing conductor cross-section for the same
length of cable.

 The shorter the transmission link, the higher the maximum possible data

transfer rate.

 If there is an active sender and an active receiver at the same end of the

transmission link, the sequence of access priority to the transmission circuit
must be taken into account in order to achieve the longest possible
transmission link.

 Signal lines and power lines must not run together. Signal lines must be

installed as far away as possible from sources of strong interference (for
example, 400 V 3-phase power cables).

 The active TTY interface with a 12 V no-load voltage has been tested on a

100 m (1100 ft) long cable at a transmission rate of 9600 bps in an
environment with normal levels of noise (field strength < 3 V/m or 1 V/ft).
If a shielded LiYCY 5 x 1 x 0.14 shielded cable is used, reliable transmission
is possible over a distance of up to 100 m (1100 ft). The AS51 1 protocol (only
one transmitter at a time) was used for testing.

Note

The interference field of the source decreases exponentially with the
distance.

Caution

Risk of damage!
The electronic components of the printed circuit boards are extremely

sensitive to electrostatic discharge. Certain precautionary measures are
therefore necessary when handling such components. These measures are
explained in the guidelines for handling electrostatically-sensitive devices at
the end of this manual.

Installing the
DIMM Cards

!

Installation

T o plug in expansion submodules, proceed as follows:

1. Open the unit as described in Section 5.1.

2. Plug the cards into the slots. Note the safety recess on the connector side
of the DIMM card.

3. Push the card down applying light pressure until it locks into place.

4. Close the unit (see Section 5.6).

Caution

Risk of damage!
Make sure that the cards sit securely in the slots, otherwise they can fall out

and be damaged.

5.5 Replacing the Backup Battery

PG 720 Expansions

Battery Power
Supply for
Real-Time Clock
and Configuration

Battery V oltage
too Low

Replacing the
Battery

A backup battery (3.6 V lithium battery) powers the real-time clock even
after the PG 720 is switched off. In addition to the time of day, all the
information about the PG 720 (device configuration) is stored in RAM. If the
backup battery fails or is removed, all these data are lost.

The clock uses very little power and the lithium battery has a high capacity
so that the battery can provide backup power for the real-time clock for many
years and seldom needs to be replaced.

If the battery voltage is too low, the time of day and the device configuration
data in the RAM are lost.

In this case, you must replace the backup battery. The battery is located on
the drive mounting.

T o change the battery, proceed as follows:

1. Switch off your PG 720 and remove the power cable and all the connecting
cables.

2. Open the unit as described in Section 5.1.

3. Now change the battery by removing the connector and releasing it from the
clip.

4. Push the new battery firmly into the clip.

5. Close the unit as described in Section 5.6.

Caution

Risk of damage!
Only replace the lithium battery with an identical battery or with a type

recommended by the manufacturer (Order No.: W79084-E1003-B1).
Dispose of used batteries in keeping with local regulations.

After you have changed the battery, you must set the configuration data of
your unit again using the SETUP program (see Chapter 6).

Starting SETUP

Your PG 720 device configuration is set for working with the software
supplied with the unit. You should only change the preset values if you have
modified your PG 720 in any way or if a fault occurs when the unit is
powered up.

The SETUP program is in the ROM-BIOS. Information about the system
configuration is stored in the battery-backed RAM of the PG 720.

You can use SETUP to set the hardware configuration (for example, hard
disk type) and define the system characteristics. You can also use SETUP to
set the time of day and date.

If incorrect SETUP data are detected when you boot the system, the BIOS
prompts you to:

 Start SETUP by pressing F2 or
 Continue booting by pressing F1.

On completion of the startup test, the BIOS gives you the opportunity of
starting the SETUP program by displaying the following screen prompt:

PRESS <F2> to enter SETUP

SETUP Menus

T o start SETUP, proceed as follows:

1. Reset your PG 720 (warm or cold restart).

2. Press the F2 key as long as the BIOS prompt appears on the screen.

The various menus and submenus are listed on the following pages. You can
get all the information you need for the SETUP entry selected from the

“Autotype Hard
Disk” Field

Figure 6-3 “Hard Disk Drive IDE Adapter” Submenu

The parameters which you can select here are usually saved on the respective
IDE drive, and are read from the drive and entered on the screen when you
select the option “Autotype Hard Disk”.

CD-ROM drives with an IDE interface (ATAPI) are not entered here.

The standard parameter “AUTO” is entered in this field. This enables the device
to recognize the hard disk parameters automatically. If you select the “Autotype
Hard Disk” field for a hard disk which does not exist, an abort is executed after
a maximum of five minutes as a result of a timeout, and the existing entries
remain unchanged. It is therefore only meaningful to carry out an autotype for
hard disks present in the system.

In the standard configuration of your programming device, only one hard
disk is entered as the master at IDE adapter 0.

In certain circumstances, it may be necessary to deviate from the proposed
hard disk parameters. In this case, select the corresponding menu option and
then the desired value using the [+] and [–] keys. Enter “none” in the “T ype”
field if an IDE hard disk or an IDE CD-ROM is not connected, or a number
from 1 to 39 if a predefined type of hard disk is to be used.

Select “User” if you wish to define your own type of hard disk; you must
then additionally enter the hard disk parameters in the fields “Cylinders”,
“Heads”, “Sectors/Track”, “Write Precomp”.

The number of sectors which are transmitted per interrupt are transferred in the
“Multi-Sector Transfers” field. The value depends on the drive and should only
be set using the autotype function.

Disabled 1 sector
2,4,6,8,16 Sectors

“Enabled” in the “LBA Mode Control” field (enabled, disabled) means that hard
disk capacities greater than 528 MB are supported. The value depends on the
drive and should only be set using the autotype function.

The type of access to the drive is defined in the option ”32 Bit I/O”:

Disabled 16-bit access
Enabled 32-bit access

The transmission rate to the IDE drive is set in the “Transfer Mode” field. The
value depends on the drive and should only be set using the autotype function.

The following settings are possible:
Standard, Fast PIO1, Fast PIO2, Fast PIO3, Fast PIO4.
You should never set a higher Fast PIO mode than that set by the autotype

function.
We recommend that you use the autotype function.
With specific operating systems, such as SCO OOT3.0, SORIX, etc., you may

have to set the “LBA Mode” to “disabled”.

A cache is a fast intermediate memory located in the CPU. Repeated memory
access operations can be carried out more quickly via the fast cache,
provided the feature is enabled. It may be necessary to disable the cache
when using certain hardware or software, because intentional program run
times or delay times are prevented by the fast cache.

8.2 Interrupt Assignments

Interrupt
Assignment

Priority

I/O Addresses of
the Interrupt
Controllers

The PG 720 uses the two integrated interrupt controllers of type 82C59 to handle
the 16 hardware interrupts (IRQ 0 to IRQ 15).

The INT output of the slave controller is connected to the IRQ 2 input of the
master controller. Interrupt 9 (IRQ 9) can be used on the bus for the assigned
interrupt 2 (IRQ 2). In the initialization phase, IRQ 9 is assigned to the software
interrupt vector 0A H (IRQ 2) by the ROM-BIOS.

The priority of the interrupts is in the reverse order of their numbering. This
means the following:

 Interrupt IRQ 0 has the highest priority and interrupt IRQ 7 the lowest.
 For triggering IRQ 2, interrupt IRQ 8 has the highest and IRQ 15 the lowest

priority. Interrupts IRQ 8 to IRQ 15 therefore have higher priority than
interrupts IRQ 3 to IRQ 7.

 The interrupt vectors are initialized and masked when the PG 720 is powered

up.
