2 BUS EXPANSION CARD ADDENDUM

INTRODUCTION

This document supplements the ADAM System Installa­tion Guide, document number 9330-7467-000. It de­scribes the usage of Bus Expansion (BX) cards with the
intercom system.

GENERAL DESCRIPTION

Bus Expansion (BX) cards permit interconnection of mul­tiple ADAM frames to increase the size of an intercom
system beyond a single frame. When a single ADAM
frame is used in a stand-alone configuration, it provides
up to 136 intercom ports, with 8 intercom ports being pro­vided by each of the Audio I/O cards in the frame. Stan­dard configurations for a single-frame intercom system
are diagrammed in the ADAM-101 through ADAM-108
Drawings in the ADAM System Installation Guide.

To increase the intercom system size, Bus expansion (BX)
cards are substituted for Audio I/O cards in selected card
slots of each frame. Coax cables interconnect the BX
cards to allow communication between the frames. Each
frame requires a separate BX card to communicate with
each of the other frames in the system. Table
total number of ports provided, and the number of BX
cards required as frames are added. Tables 2 through 6 on
pages 6 through 8 summarize how the card slots are allo­cated for various sizes of intercom systems.

DIP switches on the BX cards specify the frame number
where each BX card is used and also the total number of
ADAM frames in the expanded intercom system. Settings
for these DIP switches are summarized in Tables
on page 9. Additionally, there is a DIP switch on each BX
card to enable/disable test audio. This feature allows the
BX cards to perform certain self diagnostic functions that
may help the system to recover if the communication path

1 shows the

7 and 8

is temporarily lost. The setting of this switch is described
in the installation notes which follow.

In multi-frame systems, it is necessary to define one
frame as the master frame (frame #1) and all other frames
as slave frames. This is accomplished by DIP switch S1-7
on each Master Controller card. This DIP switch should
be set to "on" for both Master Controller cards in the mas­ter frame. It should be set to the "off" position for all other
Master Controller cards in all other frames.

The Master Controller cards also require different firm­ware, dependent on how many frames are being intercon­nected, and whether a card is intended for use in the
master frame or a slave frame. To distinguish between
cards with different firmware, a 3-digit suffix number is
stamped on the card after the assembly part number (for
example, Master Controller cards for the master frame in
a 3-frame system will be stamped with assembly part
number 9030-7514, and the suffix number will be -300) .
The various suffix numbers are indicated in Tables

2

through 6.
Each ADAM frame requires its own Master Controller

Breakout Panel. The Master Controller Breakout Panel for
frame #1 has a special function. It provides the connec­tions for the configuration computer and any program as­sign panels or UIO-256 frames that are used by the
intercom system. The Master Controller Breakout Panels
for the remaining frames are then connected back to the
primary Master Breakout Panel for Frame #1. Connec­tions between the primary Master Controller Breakout
Panel and the other Master Controller Breakout Panels are
summarized in Table

9 on page 9.

For proper operation, the BX cards must be intercon­nected in a specific pattern. Card interconnections are
summarized on page 5.

The general method of connecting Station Breakout Pan­els to all ADAM frames in an expanded system is the
same as for a single-frame system. Typical connections of
Station Breakout Panels are diagrammed in the ADAM­101 through ADAM-108 drawings in the ADAM System
Installation Guide. However, note that the addition of BX
cards causes some of the port numbers to shift to new
slots. The port numbering information contained in Tables

2 through 6 in this addendum can be used to label the Sta-

tion Breakout Panels in an expanded intercom system.
Once all components of the expanded intercom system are

properly connected, operation is identical to a single­frame intercom system.
