21 CS586 RS232 INTERFACE
The CS586 is a low cost add-on module that fits neatly into any CSx75 system enclosure
and provides a standard RS232 bi-directional DB-9 connector for connection to a home
automation host system. A simple three-wire connection to the main control is all that is
required to fully integrate this card into the system.
The CS586 can be used on a CS175 control panel to provide an RS232 up/download
functionality. It is built into the CS575 and CS875 control panels.
The CS586 has several levels of security that can be programmed at the time of
installation to allow as much or as little security system information to be passed to the
host system. It can also be set to limit the commands that are accepted from the host
system to prevent unauthorized attempts to override the security system status.
The unit can be easily configured for communication in an ASCII or binary protocol. A
selectable baud rate can be set from 600 baud to 76.8k baud with hardware RTS and
CTS handshaking. The ASCII implementation is easy to use and debug with standard
programming tools. The binary version is a more efficient method for transferring
information between the two systems. The system integrator can select any number of
events or conditions to cause the CS586 to send the relevant information to the host
without polling. This allows for a faster response to activity than polling alone can provide.
All security system information can be requested anytime if enabled to do so by the
installer. This is useful at system initialization and at periodic intervals to keep the two
systems in sync without worrying about missing any transitional event. This information is
organized as system, partition, zones and outputs. System information contains
information such as power status, phone line condition, module troubles and other system
wide conditions. Partition information includes readiness of all zones assigned, armed
state, entry/exit delays, last user number, alarm condition and many other conditions
within a specific partition. Zone information includes faults, alarm memory, bypasses,
troubles, tampers, low batteries, missing and partition assignments. Output messages
include commands that can be passed to, or from, devices in X-10 compatible format.
