Outputs
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 1Amp, 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 opened, the
output pulses low starting at 1/3 of the door open too long time
and changes to a steady low anytime the door is in alarm.
These open collector outputs reset automatically when the
door is closed.
Communications
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 utilized 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 DSX-LAN(M) serial
device at the Master Controller receives the communications
over the LAN 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 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
asynchronous, full duplex mode, operating at 9600 baud, the
method of communication 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 Controller 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 MCI is
not required for the new DSX-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 providing 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 a DSX-
1035 Quadraplexor.
