Introduction

Guide to Reader

This manual provides information on the complete procedure for the installation and commissioning of the Stentofon TouchLine Display System.
The manual deals with the installation and commissioning of Display System only, and not the standard installation and commissioning of the TouchLine exchange (refer to the standard "Installation & Commissioning Manual" for TouchLine exchanges).
The manual shows how to add the Display System to an existing TouchLine System. It is divided into the following parts:

• A short description of the necessary equipment
• Installation
• Programming
• Upgrading (to DCB 03.00/Customizing
• Troubleshooting
• Appendixes

In the Appendixes you will find the necessary cable drawings, technincal specifications, additional programming information, information on connection and set-up of terminals, schematics, and the stanard screen/display texts.

General Description of the STENTOFON TouchLine Display System

The Display System requires the following equipment:

• Display Stations
• ABD2/ABD Board (Subscriber Board with data transmission)
• PMFR board (or PMF with software version 01.30)
• DCB Board (Display Controller Board)
• Data Terminal (to program the DCB Board)

The Display System provides a great number of useful display features for the Stentofon intercom user.

The following paragraphs gives a brief electrical description with a Block Diagram of the Stentofon TouchLine Display System:

• The PMFR board continously reports the status of all stations in the system through Port B (standard exchange output)
• The DCB board identifies the status of each station and serially transmits appropriate display infromation
• The serial display information is modulated. The data is transmitted together with audio to oudspeaker through the a/b circuit
• The Display Station provides a demodulator and microprocessor which receives data and controls the display

The Reader

This manual is aimed at personnel who have earlier installed TouchLine Exchanges, and people trained at STENTOFON's installation courses.

Limitations

Maximum Number of Display Stations when using ABD boards 1000610110

Due to the high power consumption when using Display Stations, the number of Display Stations connected to each exchange is limited to 75% of the total number of subscriber boards when ABD boards are used. The limitation concerns all exchanges, except for Exchange 52/8.
The table shows the maximum number of ABD boards 1000610110 and Display Stations which can be used in different exchange sizes. As a general rule, a maximum of 15 ABD boards can be installed in each BWAP Module.
NOTE:

When using ABD2 boards 1000610120 each BWAP module may be fully equipped with 20 ABD2 boards.

The PMFR board fits into the PMC/PMF position in the modules BWCPR, BWSPR, BWFP or BWBP.

Display Controller Board DCB 1000638740

This board has standard display software, and is required when using Display Stations. The board provides a modulator circuit which enables data transmission to the Display Stations through the loudspeaker (a/b) circuit. One board is required in each exchange.
The DCB board fits into the PMX position in all exchanges in the modules BWCPR, BWSPR, BWFP or BQBP.

Data Terminal

When programming the TouchLine Display System (the DCB board), a data terminal is required. The data terminal must provide an RS-232 or RS-422 port interface. In Appendix H you will find information on terminal types and set-up standards.

Installation

Installation Overview

This section shows how to prepare and install the necessary equipment when adding a Display System to an existing TouchLione System.
The installation consists of the following step:

• Planning the installation
• Transferring Customer Data from PMC/PMF to PMFR (if necessary)
• Installing ABD2 boards or ABD boards
• Plugging in Display Stations
• Executing the Basic Test for Display Stations (as for standard stations)
• Installing the DCB board
• Installing the Display Data Cables
• Cable connection between the PMFR board and the DCB board
• Connectiong a data terminal to the DCB board

Planning the installation

Display Stations can be used together with other standard stations in the same exchange, but Display Stations must be connected to an ABD2 or ABD board. Each board contains circuitry for 4 stations, which either can be Display Stations or tandard sations.
The board must have the correct switch settings according to the type of stations that are connected to the corresponding Physical Positions. Both boards provide a 4-pole dip-switch. Each switch refers to a physical position.

► First, always decide which physical positions in your exchange are to be prepared for Display Stations. Make a note (for example "DS") for each of these Physical Positions in the column for "Special Notes" in the "Programming Journal".

► If ABD boards are used, remember the limitations, section 1.4.

Your starting point determines how the installation and commissioning of the STENTOFON TouchLine Display System is executed:

► If you are going to update an existing TouchLine System, proceed through this manual section by section.

► If you are going to carry out an installation and commissioning of a complete STENTOFON TouchLine Display System from scratch, refer to standard "Installation & Commissioning" instructions for TouchLine exchenges.

Remember that the PMFR bord (or PMF with software version 01.30) must be installed during the standard installation and commissioning. Install all board, except for ABD2/ABD boards which are installed at a later point.

When the standard installation and commissioning is completed, continue by following all procedures in this manual, except for subsection 3.3, "Transferring Customer Data from PMC/PMF to PMFR".

Transferring Customer Data from PMC/PMF to PMFR

The STENTOFON TouchLine Display System requires the microprocessor board PMFR 1000631690 (orPMF with software version 01.30). If the existing exchange is equipped with PMC or PMF board, customer data must be transferred from the PMC/PMF board to the PMFR board.

► Skip this subsection and go to the next (3.4) if this is an installation and commissioning of the complete STENTOFON TouchLine Display System from scratch.

Depending on what kind of microprocessor board your exchange is equipped with, transfer data by doing one of the two following operations:

1) When replacing PMC or PMF without EEPROM back-up with PMFR, normal tape back-up procedures must be used to transfer customer data from PMC to PMFR.

• First, dump the customer data from the PMC board onto a tape.
• Verify the tape content by running a verify sequence.
• Load the customer data from the tape onto the PMFR board.
• Verify the loading.

A detailed description of this procedure is included in the "Installation Manual"" and "Programming Guide" for TouchLine exchanges.

2) When replacing PMF board 1000631600 (EEPROM back-up for customer data) with PMFR, the following procedure is required:

If your EEPROM back-up has to be updated:

• Prepare the existing PMF board for dumping. Insert the EEPROM's and set the dip-switches in the correct standard position according to the type of EEPROM which is used.
• Dump the program (from the Programming Panel: Dial E25 + EEEE + ACT).
• Insert the EEPROMs on the PMFR board.
• Load with E26.

If your EEPROM back-up is updated:

• Insert the EEPROMs on the PMFR board.
• Load with E26.

A detailed description of this procedure is included in the "Installation Instructions" for the PMFR board, IM-1567.

Installing ABD2/ABD Boards

ABD2 Boards

Each module may be fully equipped with ABD2 boards (maximum 20 ABD2 boards in a BWAP module).

ABD Boards

If ABD boards are used, remember the maximum number of ABD boards in an exchange, refer to the table in section 1.4.1.

Board Position

The following modules provide AB positions for ABD2/BAD boards (or AB boards):

• BWAP module
• BWCPR module
• BWSPR module

Switch Settings

Each ABD2/ABD board must have the correct switch settings according to the type of stations that are connected. There are 4 dip-switches, each one referring to a physical position.

For ABD2 boards:

Switch 4 refers to the uppermost Physical Position on the backwiring - switch 1 to the lowest Physical Position.

for ABD boards:

Switch 1 refers to the uppermost Physical Position on the backwiring - switch 4 to the lowest Physical Position.

► A Physical Position is prepared for a Display Station when the corresponding switch is in ON position.

► A Physical Position is prepared for a standard station when the corresponding switch is in OFF position.

The following example shows how to set the switches when two Display Stations and two standard stations are connected to Physical Positions in an AB position (Physical Position 50, 51, 52 and 53):

Settings on ABD2:

Position:	Switch	ON/OFF
50	4	ON
51	3	ON
52	2	OFF
53	1	OFF

Settings on ABD:

Position:	Switch	ON/OFF
50	1	ON
51	2	ON
52	3	OFF
53	4	OFF

● Set the correct switch settings according to the notes you have made in the column for "Special Notes" in the "Programming Journal".

Inserting the board

NOTE!

• Before inserting or removing any of the printed circuit boards, make sure that the mains power is OFF.
• Be aware of static electricity.

• Set the correct switch settings according to the notes you have made in the column for "Special Notes" in the "Programming Journal".
• Insert the boards in the selected AB positions in the exchange.

► The boards are testet by establishing connection to all Display Stations to the boards (refer to subsection 3.6).

Plugging in the Display Stations

Your TouchLine Exchange is now installed, programmed and testet according to standard "Installation & commissioning" instructions for TouchLine Exchanges. All necessary boards, including the ABD2/ABD boards.

● Plug the Display Stations in the correct wall sockets according to the plan you have made in the "Programming Journal".

► Remember, the corresponding Physical Positions must be prepared for Display Stations!.

► At this point the Display Stations are installed for the Basic Test of standard intercom features, not Display Features.

Basic Test of Display Stations

The following procedure describe the basic test of standard intercom features for the Display Stations. During the test, connection is established to all Display Stations. In this way, the ABD2/ABD boards are also tested, except for display features. The test procedure may vary a bit depending on the type and size of the exchange which is installed. The following instructions describe therefore the test in general:

• Set up conversation between the two stations by dialling from A to B, and then from B to A.

- Test the voice switching (Duplex) and the manual switching (Simplex).

- Test the cancelling from either side and the "Do not Disturb" (Private/Open) features.

• Check the following points on all the Display Stations:

- The keyboard 0-9

- The volume control

- The PRIVATE/OPEN switch

- The M-key

- The C-key

- The Display Station's own number

► The station verifies the correct number by responding with a rapid "attention" tone (-very rapid pulses for four seconds, followed by a normal, muted busy tone).

• Continue connecting the remaining Display Stations, one at a time. Repeat the test procedures for each new Display Station (for example, set up conversation between two stations by dialling from C to B, and then from B to C, and so on).

• If faults appear, refer to Faultfinding Procedures in the standard "Installation & Commissioning" instructions for your exchange.

► For detailed information on test procedures, refer to standard "Installation & Commissioning" instructions for TouchLine Excheanges.

Do not recharge the battery.
Do not dissemble or incinerate the battery.
Do not expose the battery to heat above 85°C.

● Insert the DCB board in the PMX2 position in your exchange.

► PMX2 position is recommended. If you already have an additional feature board in this position, the PMX1 position can be used. Make sure that the Display Data Cable, the cable between PMFR/DCB and the Terminal Cable on the back-wiring is connected to the corresponding PMX position.

Connectiong the Data Terminal to the DCB Board

In order to program the DCB board, a terminal is required. The data terminal must provide an RS-232 or RS-422 interface. Remember that switch S15-5 on the DCB board must be set according to the type of terminal which is used (Section 3.7.4). For further information on terminal types, refer to Appendix H, "Connection and Set-up of Terminals".
If the terminal has an RS-232 interface, the terminal must be connected to the RS-232 input port on the DCB board (position PMX2), i.e. side A.
If the terminal has an RS-422 interface, the terminal must be connected to the RS-422 input port on the DCB board (position PMX2), i.e. side B.

● Consult the drawing and connect the terminal to the TouchLine exchange.

LED Behaviour

There are 3 different LEDs on the DCB board (RUN, IDLE and STATUS), situated on the upper right corner:

RUN - This LED is lit (steady light) during normal operation. 
A blinking LED indicates that the processor is not running due to some hardware error, or a software configuration problem.
IDLE - This LED is off when the processor is not working. The LED lights up when the processor is working (transmitting/receiving data).
STATUS - This LED is mostly off (it flickers randomly) during normal operation.
When the DCB board is in programming mode (the green button is pressed quickly), the LED blinks with a fixed frequency of approximately 0,5 Hz. 
Neither the displays nor the terminal will work when the DCB board is in this mode.

(The menu for function names/numbers appears only if you have a standard display system with the default name lengths).

<br\> TIP: You may wish to add a #secret" subscriber name/number to the system, so that the name and nnumber of a subscriber is not included in the Name List (directory), but shown only on the terminal and on your display station during connection with this subscriber. To hide this subscriber number/name, you have to enter a sorting code (digit) for this subscriber that is not listed in the above table (for example 0 or *. <br\>

b) If you have entered an ordinary subscriber number/name (not a function), the following applies:

● To indivate that the subscriber has a display station (x), press digit 1 (similar to dialling 789 on a station). (To remove a station's display status, press digit 1 once more.

● To indicate that the subscriber has a Pager (x), press digit 2.

● If you want to save the existing programming for the Single Touch keys 8 and 9, press digit 3 (required e.g. for ITS stations). If not, the system will automatically assign the "Directory" and "Info" to these keys.

<br\>

● When all information is entered, return to System Setup Menu by pressing "ESC".

If you want to list all the names you have entered, you can execute command 2 "List All Subscribers". Refer to subsection 4.8.3. <br\>

Changing Password

Step 4: Change Password (command 7) The very first time command 7 is executed, you can use "Enter" (as the "old" password does not exist"). The "new" password may then be entered. This password must be digits between 0 to 9 and letters A to F. The System Setup Menu is protected by this password to avoid unauthorized change of programming. (In addition, command 4 and 5 should be given special access restrictions, refer to Section 4.8.3).

● Press digit 7 and write old password, or press "Enter".

● Write new password (4 characters), then press "Enter".

A wrong password entry will reveal an error message: "Wrong Password". If the wrong password is entered by mistake, press "ESC" and try again.

When the password is entered, the system will automatically return to the System Setup Menu.

Identifying the Display Stations

At this point, you have entered the Display Stations' intercom number/name and display indication (Di) via a terminal. If all the display stations were plugged in the wall sockets during installation (Section 3.5), the general display layout will automatically appear on the display (refer to Section 4.6). The date, time, number and name is shown (the following is an example):

1993-02-12 09:58
299 Bolten M.A.

► The station identification code 789 must be dialled whenever a station looses power due to unplugging.

If you have not plugged a display station in its wall socket, plug it in, and the following message appears on the display after a short moment:

Activate With
789

● Dial the station identification code 789.

The identification takes a couple of seconds.

  Own Number
299 PII54 Ri3800

After a short moment the display shows the following information:

1993-02-12 09:58
299 Bolten M.A.

General Display Layout

The Display Station has a display (LCD) with two lines of 16 characters each. The following example shows the display information when a station is in "stand-by" mode (normal idle). The display indicates the date, the time and the owner's staion number/name (may vary depending on language):

1993-02-12 09:58
299 Bolten M.A.

Numbers for the "Directory" and "Info" Feature

The Name List in the system makes it possible to have a "help" feature. This feature makes it easy for the intercom user to search for functions (after pressing the "Info" key), or to search for an intercom number for any subscriber in the system (after pressing the "Name" key).
In order to use the "Directory" and "Info" Feature, two Single Touch keys are assigned these features:

Key 8 is assigned the "directory Feature"

Key 9 is assigned the "Info Feature"

The keys are automatically assigned the "Directory" and "Info" Feature during station identification (unless you have "locked" the existing programming for these keys in the System Setup Menu "Enter Subscriber Name and Information").

Commands Used for Service And Customizing

routine Inspection / Correction of Tables

Every time a routine inspection/correction of tables is done, the followng operations must be done first:

● Dial E62, press READ, DCB0, then ACTIVATE.

If no communication is possible using E62:

● Press the green button until the lowet LED starts flashing. This will program the data line speed to 9600, and displable the software (both terminal and station displays are "dead" when the lowest LED flashes).

The subscriber names are listed alphabetically. Use the <ARROW> key to move to the next page.

● To search for a specific name, press ● and the first letter(s) in the name.

The screen will show the name(s) of the person(s) you have searched for.

You can also perform a general search, using one or several criterias. You can search for names or functions by entering variuos search texts, for example, numbers, names, functions, subscribers with display indication (Di), subscribers with pager indication (Pg), etc.

● Use the <ARROW-right> key to position the cursor straight above the first character in the search criteria(s) you are to use.

● Enter the search text, then "Enter"

Example: You want to search for all the subscribers who have pagers:

● Position the cursor straight above P (in the text Pg) and write Pg, then press "Enter"

Example: You want to search for all the subscribers who have pagers and those with names starting with B:

● Position the cursor straight above the letter N (in Name) and write B.

● Position the cursor straight above the letter P (in the text Pg) and write Pg, then press "Enter".

Customizing Screen / Display Texts

Command 4 "Customize Display Text" and command 5 "Customize Screen Texts" should be given special access restrictions to avoid unauthorized changes. To execute these commands, value 0001 must be set to adress A208 in the operator's communication code E62 (refer to Appendix G). The default setting is 0000.

● If you are not planning to customize the screen/display texts, make sure that value 0000 is set to adress A208 in the E62 table.

Section 5.3, "Customizing Screen/Display Texts", provides detailed information on the necessary preparations and procedures.

Upgrading / Customizing

Introduction

The current version of the DCB board, version A6, is prepared for;

● EEPROM Back-up of Name Tables

● Customizing scrren texts

● Customizing display texts

DCB Firmware

To upgrade earlier versions of DCB boards (A5 or earlier), you need:

● EEPROM for back-up

Type 28256 - position F

● EPROM - DCB software version DCB 03.00

Type 27512 - position A

● EPROM for Screen/Display Texts - DCB 03.00

Type 27256 - position G

Upgrading to Software Version DCB 03.00

To upgrade your DCB board, perform the following procedure:

CAUTION

Before inserting or removing the DCBboard, make sure that the mains power is OFF. Be aware of static electricity.

● Remove the DCB board.

● Carefully remove "old" EPROMs, and insert new ones in the correct positions:

- EPROM (DCB version 03.00) in position A

- EPROM (DCB version 03.00) for screen/display texts in position G

● If you already have an EEPROM backup of the name tables (applies to software version DCB 02.00 only), do not remove this one (position F).

● If you do not have an EEPROM for back-up, insert the EEPROM in the correct position:

- EEPROM for back-up in position F

● Make sure that the straps are correctly set;

    ●●●●

To execute these commands, value 0001 must be set to adress A208 in the operator's communication code E62. The default value for this adress is 0000 (refer to appendix G).

● From the Programming Panel, set value 0001 to adress A208 in the E62 tabe.

● To customize screent texts or display texts, enter the System Setup Menu on your terminal and execute command 4 or commmand 5, respectively.

● Use the <ARROW-Up> key or <ARROW-Down> key to move to the next or previous text.

Appendix J provides a default list of the default Screen Texts and Display Texts which are used in the Display System.

● When you have found the text you wish to change;

- use the <ARROW-right> key to move to the first letter in the text and overwrite the existing text with the new one.

- if necessary, use the <SPACE> key to delete a single letter.

● Press <ENTER>

Applies to Screen texts only:

If you want to see the changes you have done before you continue editing the next text, press <ESC> three times.

● When you have completed the procedure, press <ESC> to return to the System Setup Menu.

● To restrict access to command 5 and 5, set value 0000 to adress A208 in the E62 table.

Troubleshooting

This section provides a check list. It is intended to be a guide for the technician during commissioning of the STENTOFON TouchLine Display System.

● If problems occur, go through this check list.

CHECK LIST CABLING Check that the Display data Cables are connected to the correct positions on the back-wiring. Check that the cable between the PMFR board and the DCB board is connected to the correct positions on the back-wiring. Check that the cable from the terminal is connected to the correct position on the back-wiring (Position PMX2 -Port B). Check that the cable connections to the terminal are correct according to the specific terminal type. CIRCUIT BOARDS Check that circuit boards PMFR, ABD2/ABD and DCB are inserted in the correct positions. Check that the ABD2/ABD boards are inserted in the correct positions according to the plan you have made in the "Programming Journal". Check taht the DCB board is inserted in the correct position (PMX2) according to the cabling (Display Data Cables, cable between PMFR/DCB and cable to the terminal). SWITCH SETTING Check that each ABD2/ABD board has the correct switch setting according to the type of stations that are connected to the corresponding Physical Positions. Check that the DCB board has the correct switch setting. Note the switch that represents Port B (RS-232 or RS-422 interface for terminal. PROGRAMMING If necessary, repeat the entire programming (Section 4). If the screen on the terminal is not correct, you may have selected the wrong terminal type in the "System Cold Start" procedure. Repeat the command, and make sure to enter the value for the correct terminal type. Appendix A - Display Data Cables - Exchange 52/8
