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.

BUS EXPANSION CARD ADDENDUM 3

INSTALLATION NOTES

When installing Bus Expansion cards to create multi­frame ADAM Intercom systems, refer to the following
notes as a supplement to the ADAM System Installation
Guide.

DIP switch S6-4 on each BX card is a test audio dis-

●

able switch:

On (closed) disables test audio
Off (open) enables test audio

Notes to Paragraph 2 of the ADAM System Instal­lation Guide: Mounting the Central Matrix Com­ponents

Label the ADAM Card Frames as “Frame 1”, “Frame 2”,
etc. The numbering of the frames is completely arbitrary.
However, the configuration computer must be connected
to the Master Controller Breakout panel for whichever
frame you designate as frame 1. If your intercom system
uses a Trunking Master Controller, or Program Assign
Panels, or UIO-256 Frames, these must also be connected
to the Master Controller Breakout Panel for frame 1.
Therefore, you should number the ADAM Card Frame
which is closest to these devices as “Frame 1”.

Notes to Paragraph 3 of the ADAM System Instal­lation Guide: ADAM Circuit Cards

All Cards

Install all cards in the proper slots using the slot usage ta­ble that is appropriate for your intercom system (Tables
through 6 on pages 6 through 8). Be sure to read the fol­lowing notes for each card type before installation.

Master Controller Cards, Suffix Numbers

Check the suffix number on each Master Controller card
to make sure it is being installed in the correct frame. The
suffix numbers are summarized in Tables 2 through 6 of
this Addendum.

2

The test audio provides enhanced error correction for
communication between the ADAM frames. When
interconnecting more than two frames, always leave
DIP switch S6-4 in the “Off” position on all BX
cards. In a two-frame system, you can also set S6-4 to
the “Off” position; however, you will not be able to
use ports 125 through 128 of frame #1 and ports 253
through 256 on frame #2, since these ports must be
used for the test audio.

DIP switch S6-8 on the BX cards is not used, and the

●

position does not matter.

Notes to Paragraph 9 of the ADAM System Instal­lation Guide: Connections to the ADAM Card
Frame

Connections to Audio I/O Cards and Master Con­troller Cards

Connections to the AIO and MC cards for all frames are
as shown in the ADAM-101 through ADAM-108 Draw­ings in the System Installation Guide. The only differ­ences are that the slot numbers and port numbers for the
Audio I/O cards will vary. (Use the slot numbers and port
number shown in Tables
place of the slot and port numbers shown in the ADAM­101 through ADAM-108 drawings.)

Master Controller Breakout Panel Interconnec­tions

2 through 6 of this Addendum in

Master Controller Cards, Master vs Slave Frame
Selection (S1-7)

In Frame #1, set DIP switch S1-7 on both Master Control­ler cards to the “on” position. For all other Master Con­troller cards in the remaining frames, make sure that DIP
switch S1-7 is set to “off” (factory default setting).

BX Card DIP Switches (S6)

As you install each BX card, make sure that the S6 DIP
switches are properly set:

Set the frame number using Table 7, page 9.

●

Set the total number of ADAM frames using Table 8,

●

page 9. (All of the BX cards will have these switches
set the same.)

4 BUS EXPANSION CARD ADDENDUM

A connection is required from the Master Controller
Breakout Panel of frame #1 to each of the other Master
Controller Breakout Panels. Refer to Table 9, page 9. Use
single-pair data cables for the connections (same type as
is used to connect a PAP-950-50 as shown in the ADAM­809 Drawing in the System Installation Guide).

Configuration PC, Trunking Master Controller,
UIO-256, PAP's

These devices should only be connected to ADAM frame
#1. Connections are as shown in the ADAM-101 through
ADAM-108 drawings in the System Installation Guide.

Bus Expansion Card Interconnections

Interconnections for a 6-Frame System

The Bus Expansion cards must be interconnected using
coaxial cables. Use the following information when mak­ing the interconnections. Note that when interconnecting
Bus Expansion cards, the “TX” jack (top jack) of the first
card connects to the “RX” jack (bottom jack) of the sec­ond card and vice-versa.
