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. Pre-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]).

Installation and Connections

The power supply is connected via P1, green power connector to +13.8 Volts and Ground. The supply input is protected against reversed connection.

Indicators

There are 6 indicators on the top panel consisting of:

Purpose	Label	Description
System Error	ERROR	The RED error LED will indicate when there is a system

error. A flashing RED LED indicates the unit cannot communicate with the transmitter or an adjacent input module, or if the message buffer is full
Upstream Receive Data| RX DATA| This GREEN LED flashes to indicate serial data is being received from an upstream device
Upstream Transmit Data| TX DATA| This RED LED flashes to indicate serial data is being transmitted to an upstream device
Power Indicator| SYSTEM| The GREEN power LED, which normally flashes ON once per second to indicate healthy micro-controller operation. After a de-bounce period, the green LED will flash rapidly if the low supply detector is activated
Downstream Receive Data| RX DATA| This GREEN LED flashes to indicate serial data is being received from a downstream device
Downstream Transmit Data| TX DATA| This RED LED flashes to indicate serial data is being transmitted to a downstream device

Operation

Each input module will send its 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 PC 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).

Error Codes

Error Code	Description
ER2 NOACK	The downstream device failed to acknowledge the last sent message
ER6 BUSY	12-32 is too busy to process the received message – memory is full

TroubleShooting

The following table may help in problem solving where necessary:

Fault	Check
No illumination of Green LED	Bad power supply connection
Input activated but no message sent	PSD configuration incorrect
No RS232 serial communication	Comport connections, baud-rate 9600 no parity,

eight data bits, one stop bit
Red LED flashes rapidly| Downstream device not acknowledging – check serial cables and traffic LEDs.

Device is busy – memory is full or transmitter unable to clear volume of messages.

Green led flashes rapidly| Low supply detector threshold

Programming

Preparations for Connecting the Programming Software
To change the field programmable options, the unit must be connected to a PC running the 12-32 PSD programming software in Windows XP via the standard serial port S1 (Upstream / Programming) connector.

Note: To make up a serial cable, the S1 (Upstream/Programming) connections are shown earlier. Alternatively purchase an optional Salcom serial programming cable.
Note: The 12-32 must be powered during programming.

Ensure that the 12-32 PSD has the correct com port selected. Once correctly configured perform the following:

Press connect. The status at the bottom of the 12-32 PSD will indicate if successfully connected.
Press the read button, or load a PSD configuration file. This will load all settings of the 12-32, which is required before any changes can be programmed. The 12-32 PSD will provide feedback if the user selected operations are successful.

Using the Programming Software
The 12-32 PSD allows the user to configure the following characteristics:

Input actions, watchdog and low supply detector settings
Pre-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
Page beep levels 1-4.
RIC Code:
Pager ID. Valid Codes are:
- 0000008 to 2007663
- 2007672 to 2045055
- 2045064 to 2097143
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 Watchdog:
When the watchdog is enabled, the input message will be sent periodically as configured if in the enabled state. When using this feature, the watchdog must be enabled and use a valid RIC code.
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 Debounce:
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. Previously saved configuration files can be loaded and edited with, or without a 12-32 connected.
