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.
