General Information

The Model 12584-002 I/O Control Module is designed to monitor contact closure devices connected to its
input, and to turn devices on or off that are connected to its output. It operates as a slave device reporting
to a syste m ma ster controller via a seri al data line conn e c tion. The ma ster c ontr oller is programmed to
recognize the I/O Control Module and process the data information received from it.

Typically, the system master controller is a
computer or a GAI-Tronics Model 10959
Series Audio Messenger Interface (AMI). In
special applications, the system master
control ler can be another I/O Control Mo dule
that is reprogrammed with custom software.

In general, the Model 12584-002 I/O Control
Module provides the following features:

Digital Inpu t Monitori ng

The I/O Control Module can monitor up to 32
voltage-free contact inputs. The contacts can
be normally open or closed. Additionally, they
can be momentary or maintained type
activation. The programming of the system
master controller defines how each input is activated. Each input is individually programmed for the type
of activation switch and the resulting event.

Analo g Inpu t Monit oring

The I/O Control Module monitors up to eight analog voltage inputs from 0 to +5 V dc. Each input is
individually programmed to activate on a pre-programmed voltage threshold level.

Figure 1. Model 12584-002 I/O Control Module

OTE: This feature is not available when an AMI is acting as the master controller device.

Outpu t Control

The module provides up to 32 open collector control outputs for activating devices such as relays,
indicators, or other on/off devices. The outputs can be active high (off) or active low (on). Additionally,
they can be momentary (pulsed) or maintained type activation. The programming of the system master
controller defines how the outputs are activated. Each output is individually programmed to activate
during a cert ain system event.

Accessory D evice to the GAI-Tronic s AMI

There ar e two ways the devic e can be u se d with the AMI:

• Input/output exte nsion module - This application provides 32 additional switch inputs to the AMI

that can be programmed for alarm activation, alarm reset, muting, or telephone interface control
switches.

• Serial dat a alarm control - This application allows the system master controller to activate and reset

alarms on the AMI from a remote location without using contact closure inputs wired directly to the
AMI.

Each allocation requires a unique data connection to the AMI. Refer to the Installation section for wiring
diagrams.

Data Line Selecti on and Settings

The Model 12584-002 I/O Control Module supports both RS485 and RS232 data connections. The
RJ232 connection is accessed from a male DB-9 connector. There are two different RS485 data
connections. RS485 #1 is accessed from terminal block TB1 and TB2, and RS485 #2 is accessed on an
RJ45 receptacle .

• Data connecti o n to system master controller must be ma d e using either the RS4 8 5 #1 da ta connection

OR the RS232 data connection. Both cannot be used simultaneously.
A 3-position jumper (J6) selects either RS232 or RS485 #1 data communication.

- Shor t pins 1 and 2 to sel e c t RS485 data on TB2.

- Short pins 2 and 3 to select RS232 data on DB9 connector.

RS485 #1 data connection is made to terminal blocks TB1 and TB2. Refer to Table 7 and Table 8 in
the Installation section of this manual for data line connection details.

RS232 data connection is made to the male DB-9 connector. A null-modem cable should be used for
connection to the master controlling device.

• The RJ45 receptacle connection is used exclusively for serial data control of the AMI as mentioned

above. Refer to Table 9 in the Installation section of this manual for data line connection details. Do
not use this data connection for the system master controller.

After selecting the data line type, there are several other switches on the I/O Control Module that must be
set to the proper data format to communicate with the controlling device. Each switch is labeled on the
module case. The following sections describe each switch in detail.

Address S witches S1 a nd S2

S1 an S2 are hexadecimal switches that are used to set the I/O Controller’s address. If the system
contains more than one I/O Controller, each device must be set with a different address. The device’s
addressing should be set in se quential ord er sta rting with address 01. Swit ch S2 sets the first digit a nd
switch S1 sets the second digit.

Example:
Address 01: S2 = 0, S1 = 1
Address 02: S2 = 0, S1 = 2
Address 03: S2 = 0, S1 = 3

OTE: After changing the board address, the RESET button must be momentarily depressed for the new

N

address to take effect.

DIP Switch S4

An 8-p osition DIP switch S 4 sets various data par amete rs and operation paramet ers of the I/O c ontr oller.
The following tables indicate each switch position and the corresponding settings/functions.

DIP switch S4 positions 1-3 set the serial data line baud rate as follows:

Open - will automatically send a data message when an active
input is detected. The controller will NOT wait for poll request
from the master controlling device.

Closed - will NOT return the controller’s address (set by hex
switch S1 and S2) when sending a data message to the master
controlling device.

Open - will return the controller’s address (set by hex switch S1
and S2) when sending a data message to the master controlling
device.

Closed - if data communication is lost with the master controlling
device, all outputs will remain in their current state until data
communication is restored.

Open - if data communication is lost with the master controlling
device, all outputs will flash on/off.
