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
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.
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
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.
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.
