Hot-Swap Redundant Comm Servers 
Hot-Swap Redundant Communications Servers 
provides continued availability of System 
Communications and Control through the 
implementation of Primary and Backup 
Communication Server PCs. Available only with 
WinDSX SQL the Hot-Swap Supervisor runs on 
the Backup Comm Server and monitors the 
Primary Comm Server. When the primary fails 
all communications are redirected to the Backup 
Comm Server. LAN connected locations are 
transparently transferred to the Backup Server 
and with the use of a DSX-SPS Serial Port 
Switcher all dial-up and direct serial port 
connected locations are also switched 
automatically. WinDSX SQL Workstations 
automatically switch to the backup server and 
continually display which server they are talking 
to. This feature requires the purchase of the Hot 
Swap Supervisor software and optionally the 
DSX-SPS Serial Port Switcher. 
WinDSX SQL now has the ability to log into the 
SQL Server using either network authentication 
or SQL authentication. This makes the way for 
Redundant SQL Servers working in a Cluster for 
high availability of the database. 
Hidden and Predefined UDFs 
Sensitive UDF data can now be restricted on a 
field by field basis. This allows operators to view 
and manage some UDFs while restricting 
access to others that may contain sensitive data. 
Access to the Hidden User Defined Fields is 
implemented on an individual operator basis. 
User Defined Fields can now have predefined 
choices for the operator to select from. 
High Level Elevator Control Interface 
WinDSX with the use of DSX-Soft I/O now has 
the ability to integrate with Elevator systems 
using a serial data connection instead of relay 
outputs. WinDSX is configured the same as 
before but instead of activating a relay output 
with a Code to Output Link it is activating a 
virtual output that sends a unique command 
string to the elevator system telling it to enable a 
certain floor select button in a particular cab. 
Using serial data connections instead of relay 
outputs, provide a simpler install and creates a 
more efficient and reliable system. Interfaces for 
OTIS & KONE Elevator Systems are available. 
Digital Video Recorder Integration 
WinDSX now has the ability to integrate with 
various different Digital Video Recorders. This 
integration allows stored and live video from the 
DVR to be accessed within the DSX software. 
All video is transmitted across a Local Area 
Network connection. 
Real time video can automatically be displayed 
in response to alarm events. Additionally the 
operator can request real time and/or stored 
video from the alarm acknowledgement screen 
or from any input/output or camera icon. 
Recorded Video can also be viewed while 
running a History report. Simply highlight the 
event you would like to see the video for and 
click the “Show Video” button. The system will 
find the video that matches the event, time and 
date and display it on screen. 
Temporary Access Levels 
DSX now provides the ability to assign 
temporary access levels to a card. Temporary 
Access Levels can be assigned to override the 
Card Holders normal access level on a user 
defined Start Date and then revert back to the 
permanent Access Level on a user defined Stop 
Date. This could be for an employee that would 
need access to another area temporarily. For 
instance an employee receives an assignment 
that will require him to enter the HR department 
for the next two weeks. He would be given a 
Temporary Access Level that includes his 
permanent access levels and the HR 
department level. The Temporary Access Level 
assignment would be given a Start Date of 
??/??/???? and a Stop Date of ??/??/????. On 
the Start Date the Temporary Access Level is 
applied and the Permanent Access Level is 
suspended until the Stop Date is reached 
whereby the Permanent Access Level is re-
instated. 
DSX-LAN Communications Interface 
w Modem Backup 
DSX now manufactures a LAN communication 
device to connect with DSX Controllers over a
