Product Overview
The 12-32-0000 is a 32 input expansion module that may be used either autonomously with a
serial to ethernet converter or with any transmitter that supports Salcom protocol. Input
modules may be daisy chained together to provide as many inputs as required.
A simple LCD provides indication of current inputs states and system messages. LEDs provide
indication of system health, upstream and downstream serial port activity. When a message is
generated by an input module the content of the message will display (up to the first 16
characters) on the LCD momentarily.
The 12-32 supports multiple message queuing, and will queue at least 50 messages. re-defined
input messages are limited to a maximum length of 40 characters which may be configured
using Salcom programming software.
The input module may be configured to tag each message with a source description (e.g [01]
or [Shed 1]).

Upstream
Transmit Data

Operation
Each input module will send it’s input message when triggered, to the downstream unit
(connected to the left hand side RJ12 socket). This may be either a transmitter, or another input
module. A module connected downstream will acknowledge receipt of a Salcom protocol
message, so reliable delivery to the transmitter can be ensured.
The input module may be configured to operate without acknowledging, so that input
modules may be connected to a C or unit that does not support Salcom protocol (but this is
not advised, since messages may be lost).
When configured to wait for acknowledgment the input module will attempt to resend the last
message again with a frequency as set by the user (up to every 10 seconds – default 1
second).
When a message cannot be acknowledged (probably due to a break in a serial cable link
somewhere downstream) the input module may eventually fill its message queue, and stop
acknowledging messages from upstream modules. If the input module is in an error or busy
state preventing the offloading of messages, the module “breaking” the chain can easily be
identified by inspecting the serial traffic and error LEDs.

Sending an Input Module Message
There are three ways of initiating a message sent from the input module:
•Using the external discrete inputs
•Supply detector threshold (Low supply message)
•Watchdog
External Discrete Inputs
An action can be initiated from the 32 external inputs with an input transition to LOW
(connection to GND) and/or HIGH (input floating or connection to >+3.5v).
Low supply message
After a debounce period, the low-supply detector can initiate an action for both “supply going
high” and “supply going low” conditions.
Watchdog
The watchdog feature will initiate an action after a predetermined period. The watchdog also
optionally allows the transmission of the current state of selected inputs (including supply level).

Programming
Preparations for Connecting the Programming Software
To change the field programmable options, the unit must be connected to a C running the
12-32 SD programming software in Windows X via the standard serial port S1.
Note: To make up a serial cable, the S1 connections are shown earlier. Alternatively purchase
an optional Salcom serial programming cable.
The 12-32 must be powered during programming, +13.8V to power terminals.
Ensure that the 12-32 SD has the correct com port selected. Once correctly configured
perform the following:
1. ress connect. The status at the bottom of the 12-32 SD will indicate if successfully
connected.
2. ress the read button, or load a SD configuration file. This will load all settings of the 12-32,
which is required before any changes can be programmed. The 12-32 SD will provide
feedback if the user selected operations are successful.
Using the Programming Software
The 12-32 SD allows the user to configure the following characteristics:
•Input actions, watchdog and low supply detector settings
•re-defined messages
•Configuration of input module ID (which will be added to each message sent).
Once the program is running, the opening screen appears. Use the mouse to select the
configuration fields for each feature.

PSD Input Configuration
All inputs may be configured in a similar fashion, including supply voltage monitoring. The input
drop down box provides support for all of the 32 inputs.
The battery input is at the very bottom of the input list. Each input may have a message
defined for both a high and low state. Input parameters may be configured as follows:
Pager type: Numeric or Alpha numeric. Tone only pagers are supported by ensuring that the
message field is left blank.
Beep Level: age beep levels 1-4.
RIC Code: ager ID. Valid Codes are:
0000008 to 2007663
2007672 to 2045055
2045064 to 2097143
0000000 may be used as a “drop” code. This may be used for the watchdog
when the watchdog is used, but a watchdog message is to be suppressed.
Message: User message, up to 40 characters in length.
Transmission Count: How many times that message will be sent if triggered.
Enabled: When selected, the configured message will be sent when triggered.

Resend with Wat hdog: When the watchdog is enabled, the input message will be sent
periodically as configured if in the enabled state.
Initial Input State: Input messages are sent when transitioning to the enabled state.
If on start-up “Current” has been selected the current input state is read, so that
the input message will not be sent on start-up.
If “High” is selected, the input on startup is assumed to be in the high state, so
when found to be low (if this is the case) the transition will result in a message
being sent (if enabled).
If “Low”, the opposite will occur, the input is assumed to be low on startup, the
transition to high resulting in message being transmitted (if enabled, and the
input is in the high state).
PSD General configuration
Selecting Options->General will display the general configuration screen as shown overleaf. The
following items may be set here.
Unit Id: The Identifying string (up to 10 characters) that may be prepended to each
outgoing message. Note that this ID should be numeric if numeric pagers are
being used.
Input Deboun e: The time delay between the input being triggered and the message being
sent.
Resend Delay: When an input has been configured with a transmission count greater than 1,
then the resend delay is the delay in seconds before sending the message
again.
PSD Configuration files:
The current 12-32 configuration can be saved using File-Save. reviously saved configuration
files can be loaded and edited with, or without a 12-32 connected.
