Page 3: Introduction
1. Introduction This manual describes the commands that are available to developers of third-party applications for DSC’s PowerSeries line of panels through the S5401D Serial Interface Module. For instructions on installing and setting up a S5401D module on a DSC PowerSeries panel, please see the S5401D Installation Instructions. How to Use This Document This document describes the commands available to developers of third-party applications through the S5401D interface. -
Page 4: Communications Protocol
4. Communications Protocol The module will communicate with the Application using the RS-232 interface (DB9 connector) on the board. All data is sent as hex ASCII codes. The transmission from will consist of the following: CCC DDD…DDD CKS CR/LF CCC => 3 Digit Command This tells the module or the application what to do. -
Page 5: Application Originated Commands
5. Application Originated Commands # of Data Description Command Data Bytes Bytes Poll The S5401D will respond with a Command Acknowledge code. Status Report The S5401D will send updates for all general zone, partition, and trouble status to the Application (Troubles will be limited to indicating the status of the Trouble LED on a keypad). - Page 6 occur. Code Send This command is used whenever there is a need to send a code. A command, such as Command Output, will be sent to the module and the module will then send command 900 to tell the user to enter an access code. The Code Send Access Code command transfers this code.

Page 10: Special Considerations For Some S5401D Commands
8. Special Considerations For Some S5401D Commands While almost all the commands the S5401D issues are event driven, that is to say they are issued in response to either some API command or some event within the scope of the security system, not all are. Some commands simply reflect the status of certain systems and therefore are only issued when a change of state is encountered. -
