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.
