DSX System Design Guide

Controller Architecture / Hardware

DSX Intelligent Controllers are independent processing 2 door packages designed to be cost effective building blocks that allows expansion in a scalable manner. Up to 8 doors can be controlled from 1 enclosure for an efficient space saving package. The controllers are strategically placed throughout the customer location connected together with a two twisted pair cable. Each Controller operates as a fully intelligent and independent control panel that retains all data necessary for system operation in it’s own RAM. With it’s integral real-time Clock and Calendar it performs Time Zone control with Holiday overrides for inputs, outputs, and cards even when communication to the PC or other controllers is not available.

The DSX-1048 Intelligent Controller may be used in conjunction with all other DSX Controllers as a Master or Slave in the panel network. Any controller may be designated as a Master or Slave panel. The Master or Slave mode of operation is determined by the panel’s dip switch settings. The first panel of each location is designated as the Master while all others would be considered Slaves. The Master is responsible for communications to the PC and to the Slave panels. Up to 64 - Intelligent Controllers can be used in a single Location providing 128 readers. Multiple Locations can be grouped for systems that require more than 128 readers/keypads.

General Information

The Controller Comparison Chart is great for those that are new to DSX and unsure of the attributes of each controller. Click here for more information.

The Wiring Specifications is a one stop document to find out what type of cable is to be used in a DSX system. This list of Cable is a guideline and equivalents can be used. Sorry, Cat5 cable cannot be used in the DSX system except between the network equipment and our LAN module. It cannot be used for door, reader, lock, or communication wiring or inner panel wiring.

Communication Devices

There are a number of Communication Devices that can be used with the DSX system to meet a number of different applications.

The DSX-1035 Quadraplexor is a protocol independent RS-485 multiplexor. It will take RS-232 or RS-485 as an input and will provide (4) RS-485 outputs and 1 RS-232 output for slave communications. The RS-232 output could be used to connect to a device requiring an RS-232 input such as a serial port on a Soft I/O PC or it could be connected to the RS-232 input of another DSX-1035 to get an additional (4) RS-485 outputs for slave communications. It accommodates a STAR wiring configuration and can be placed anywhere after the Master Controller. Click here for more information.

The DSX-MUX is a 6 channel RS-232 multiplexor for slave communications. In an application where you would need up to 6 RS-232 slave panel communication outputs for fiber-optic transceivers, short haul, and lease line modems. Click here for more information.

DSX-USB is a USB2.0 to RS-232 and RS-485 converter. It takes a USB input and provides both an RS-232(+dtr) and an RS/485 output simultaneously. This unit can be used for all DSX communications such as dialup modem or direct connection. Click here for more information.

DSX-MCI which is short for Master Controller Interface is an RS-232 converter that will change the RS-232 output of a PC serial port to RS-485 for greater distances than RS-232 will operate. Click here for more information.

DSX-485T is a two channel RS-485 repeater. It can be used to split an RS-485 communications line to go in two directions. It can also be connected to an older non-revised 1032 controller to make it compatible with all new panel communications. Click here for more information.

The DSX-LAN module is a Auto-sensing 10/100BaseT communications interface for DSX Controllers. It will accept RS-232 or RS-485 from the controllers and connect to a 10 or 100Mbit LAN. The workhorse is simple to install and program. There is a DSX-LAN(M) version that will allow the connection of a dial-up modem for modem backup to the LAN communications. Click here for more information.

DSX Dial-up Modem is a DSX designed dialup modem that can be used at the PC or the master controller. This modem comes with everything required to connect to any DSX Controller or PC Serial Port. Click here for more information.docs/dsx-modemcut.pdf

Reader / Keypad Interfaces

This page is dedicated to reader and keypad information and other related information.

Device Types are what tell the DSX System what type of keypad, reader, or card format to expect. With Firmware Versions 3098 and higher (1040/22) and 569 and higher (1030/21) Multiple device types can now be used simultaneously on the same reader. Click here fore more information.

DSX builds several Keypad Interfaces that allow non-standard keypads to be connected to a DSX Controller. Explore these interfaces and diagrams to see if you find what you are looking for. Click here for more information.

Reader Interfaces allow for non-industry standard card readers to be connected to DSX controllers for takeovers and change outs. Click here for more information.

Specialty Devices

This section provides descriptive operational overviews of the special modules and accessories for the DSX System.

The DSX-DP232/485 Surge Protection Modules are used to isolate the DSX equipment from external forces. Anytime a communication wire leaves the protected premises and is exposed to the elements and weather it should be isolated with the DSX surge protection modules. They can also be used to protect one system from another that are connected via a communications cable. Click here for more information.

The DSX-TDM and TDM5 are Time Display Modules that are designed to work specifically with the DSX system. They will display the system time that is being recorded when card holders use their cards. Typically used with the Time and Attendance feature in WinDSX. The TDM has a 1 inch seven segment LED display and the TDM5 has a 5 inch display. Click here for more information.

The DSX-SPS Serial Port Switcher is the device used to switch serial port connected controllers and dial-up modems between the Primary Comm Server and the Hot Swap Backup Comm Server. This is not necessary for IP or LAN based communications to controllers. Click here for more information.

Miscellaneous Interfaces is where the Duress and Door Latch modules are described. The Duress module facilitates a Duress PIN for Keypad systems that can send a silent alarm to the System front end. The Door Latch module is a device that will allow the unlocking of a door with the first card read, latch the door open with the second card read and relock the door with a third card read.
