Dial-Up Modem Communications from the DSX-1042 Master
Controller to the PC utilizes a DSX modem at the Controller
and one at the PC. At the DSX-1042 Master, the RS-232 Host
Communications Port connects to the Modem. The Modem
derives its power from the DSX-1042 panel. The Controller
auto-dials to the PC all Alarm and Supervisory conditions. The
Controller can also be programmed to dial the PC when its
event storage buffer is 80% full.
Controller Communications is handled at each DSX-1048 by a
DSX-1040CDM (communications distribution module) using
true point to point, regenerative, RS-485, 4-wire
communications. This module has 2 RS-485 ports for in and
out 4 wire communications to other Controllers. The
Controller network communications is regenerated at each
DSX-1040CDM allowing up to 4000 feet of distance between
Controllers over two twisted pair cable. The DSX-1040CDM
has 2 RS-232 Communication Ports. One is used to connect to
the Master Controller and is only used in the DSX-1048PKG
Enclosure where the Master Controller resides. The other RS-
232 port connects to the RS-232 port of each Slave Controller
in that same enclosure. DSX-1048PKG Controllers are
connected in a series loop configuration unless a DSX-1035
Quadraplexor is used for Star wiring.
DataBase Downloads
The Controllers utilize a synchronized database that is
maintained with the incremental and automatic or scheduled
downloading of changes only. This intelligent, independent
processing increases the speed of the panel’s actions and
reactions, providing more stability and security to the overall
system. The Controllers are downloaded with all parameters
the first time they are brought on-line. Once the initial full
download occurs all database changes such as the adding and
deleting of card holders are sent to the Controllers by way of
incremental downloads. The Controllers’ transaction buffer
automatically adjusts its size to utilize any RAM not allocated
for data.
Diagnostic, Supervisory and Status LEDs
The DSX-1048 has 88 diagnostic LEDs to indicate panel
status. Thirty two are for Input Status, and sixteen are for
Output Status. The rest are for Communications, Fuse Status,
and Processor Status.
