Dsx-1022 intelligent controller 2 door (board only)
DSX-1022 Intelligent Controller 2 Door (board only)
he DSX-1022 is an independent processing, two door intelligent controller designed to be a cost effective building block of the DSXhardware platform that allows expansion in a scalable manner. Up to 2 doors can be controlled from 1 enclosure allowing it to be strategi-cally deployed where a few number of readers are required such as parking garages, gates and other remote situations. This newly designed controller has several new features such as fuses in line with the common terminals on all four relay outputs. Battery Test and Load Shed are also new features incorporated into the panel to protect the panel and its backup battery. The DSX-1022 carries a Limited 2 Year Warranty.
The DSX-1022 Intelligent Controller (panel) is designed as a unitized (processor and i/o board combined) controller with small space requirements that accommodates two discreet reader/keypad controlled doors. The DSX-1022 can be used in conjunction with all other DSX Controllers as a Master or Slave in the Controller Net-work. The first Controller of each location is designated as the Master. The Master is responsible for communications to the PC and to the Slave Controllers.
The unitized DSX-1022 controller contains an AM186 processor, RAM, ROM, power supply, and removable field wiring terminals. Each DSX-1022 operates as a fully distributed processing control panel that retains all data necessary for system operation in its own RAM. Each DSX-1022 checks its database to make decisions about access control, alarm monitoring, and time zone changes. The DSX- 1022 has an integral real-time clock and calendar which allows 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-1022 is compatible with Wiegand, Barium Ferrite, Proximity, Bar Code, Magnetic Stripe, and Biometrics readers. Any combination of reader technologies may be used in the same system. A keypad may be added to most readers to create a Card and/or PIN controlled entry point. The DSX-1022 is compatible with over 160 different card readers / keypads and card formats which makes it the perfect panel for retrofits.
The DSX-1022 has a standard configuration of 512K of Flash ROM and 512K of RAM. The RAM memory allocation is dynamic between database and event storage and set for optimum use by the Host PC according to data entered for that location
The DSX-1022 has 8 EOL supervised Inputs capable of two, three, and four state point monitoring with Status LEDs. The armed status of each Input can be controlled by up to 4 Time Zones, I/O & Card Linking, and Manually from the PC. Two Inputs (input 7s) are designated as the Door Position Inputs for the reader controlled doors. Two Inputs (input 8s) are designated as the Exit Request Inputs for the reader controlled doors. The remaining four Inputs are then left for point monitoring of any contact closure output device.
The DSX-1022 has six Outputs. Two Outputs (output 1s) are the Form-C, fused at 1 Amp, relay outputs to control the locks for the reader controlled doors. Two Outputs (output 2s) are also Form-C, fused at 1 Amp, relay outputs that are programmed and used in the same ways as all other outputs. All Relay Outputs have 1A fuses in series with the Common terminal. Two Pre-Warn Outputs of the DSX-1022 are used to indicate the controlled doors are being held open and about to go into alarm. If the door is locked, armed, and open the output pulses low starting at 1/3 of the door open too long time and changes to a steadylow anytime the door is in alarm. These open collector outputs reset automatically when the door is closed.
The DSX-1022 Intelligent Controller can communicate with the Comm Server (Host PC) via TCP/IP, direct serial port, and dial-up modem. TCP/IP LAN Communications can be performed from the WinDSX Comm Server PC to a Master Controller. The WinDSX Software without the use of any additional Hardware or Software will redirect what would typically be serial port communications to a TCP/IP address. A LAN serial device at the Master Controller receives the communications over the LAN from the WinDSX PC and converts it to RS-232/RS-485 for the Master Controller. The end result is real time communications similar to that of a direct serial port connection.
Direct Connect Communications to the PC from the Master 1022 Controller is performed with the use of the MCI module which connects to the comm port of the PC and converts the RS-232 signal from the PC to RS-485 . The RS-485 communications from the MCI to the Master 1022 utilizes two twisted pair cable for the data and one pair for power. The RS-485 output of the MCI will support up to 4000 feet of cable distance. The controller communicates with the PC at a default baud rate of 9600. As long as the communications signal arrives at the Master as RS-485 and RS-232 at the PC in an asynchro-nous, full duplex mode, operating at 9600 baud, the method of commu-nication in between can be just about any mode of transport such as Direct Wire, T1, Lease Line, or Fiber Optics.
Dial-Up Modem Communications from the DSX-1022 Master Control-ler to the PC utilizes a DSX-Modem and DSX-MCI module at the Controller and a DSX-Modem at the PC. At the DSX-1022 Master, the RS-485 Host Communications Port connects to a DSX-MCI module which converts the RS-485 of the Controller to RS-232 for the Modem. The DSX-MCI and Modem derive power from the 12VDC output of the DSX-1022 panel. The Controller will auto-dial to the PC all Alarm and supervisory conditions. The controller can also be programmed to dial the PC when its event buffer is 80% full.
Panel to Panel Communications is a true point to point, regenerative, RS-485, 4-wire, communications method. This allows the panel to panel network communications to be regenerated at each controller provid-ing up to 4000 feet of distance between controllers over two twisted pair cable. Panel to Panel communications can be configured in a series loop, star configuration, or both. Star configurations require aDSX-1035 Quadraplexor.
