General Information
The DSX-1048PKG Intelligent Controller is an independent
processing 8 door package designed to be a cost effective
building block platform 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 DSX-
1048 operates as a fully intelligent and independent controller
that retains all data necessary for system operation in its own
RAM. With its 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 carries a
Limited 2 Year Warranty.
Controller Architecture
The DSX-1048 Intelligent Controller may be used in
conjunction with all other DSX Controllers as a Master or
Slave in the controller network. Any controller may be
designated as a Master or Slave controller. The Master or
Slave mode of operation is determined by the panels 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 16 - DSX-1048PKG Intelligent
Controllers can be used in a single Location providing for 128
readers. Multiple Locations can be grouped for systems that
require more than 128 readers/keypads.
Each DSX-1048PKG includes a DSX-1040E Enclosure, a
DSX-1040CDM Communication Distribution Module and 4
DSX-1042 Intelligent Controllers. Each DSX-1048 provides 8
Reader Ports, 32 Inputs, and 16 Outputs. Each DSX-1042 has
a 12 volt fused power output for its Card Readers and
Keypads. The DSX-1042 contains an AM186 processor, 512K
of RAM, 512K of Flash ROM, and a Real Time Clock. The
DSX-1048 allows all door and field wiring connections to be
made via removable terminal blocks. The DSX-1040CDM
receives RS-485 communications from a possible previous
panel and regenerates the 4 wire-RS485 to the next DSX-
1048PKG. The DSX-1040CDM also distributes Slave
Controller communication to those Slave panels located within
the same enclosure.
Used in conjunction with the DSX-1048PKG Intelligent
Controller is a DSX-1040PDP or Power Distribution Panel.
The DSX-1040PDP houses the controller and lock power
supplies, backup batteries, and fused power distribution
module. The DSX-1040PDP is comprised of a DSX-1040PE
enclosure, an SWS-150 15V power supply for the controllers,
a SWS-150[15] or [27] for either 12V or 24V locks, and a
DSX-1040PDM or Power Distribution Module.
System Power
Each Controller in the DSX-1048PKG is powered from an
individually fused 12 volt output from the DSX-1040CDM
distribution module located in the same enclosure. The module
also provides 5 volt power for those Readers and or Keypads
that require it. The DSX-1040CDM receives power from the
DSX-1040PDP Power Distribution Panel.
