Transcript NexStar High Speed Multiplexer - Honeywell Integrated Security

NexStar High Speed Multiplexer
New NexStar with S-NET, RS-485 and
RS-232 capabilities.
• Handles Home-Run S-NET Reader wiring
like conventional NexStar.
• Provides RS-232 to RS-485 conversion for
Star Controller networking.
• Allows RS-232 multiplexing at the same
time as RS-485.
The new High Speed NexStar is Baud rate
transparent at up to 38,400 baud. It also
supports optional RS-232 port converters for
anywhere from one to all five ports. This
allows it to be used for any combination of
RS-485 and RS-232 networking from a Host
system to legacy and new ACUs.
It is particularly useful for connecting the
new Star Controllers to a host via their
RS-485 port.
Example Drawings
• S-NET Multiplexing for MIRO and Reader
wiring.
• RS-232 to RS-485 conversion for Host to
Star Controller networking.
• RS-232 to both RS-485 and RS-232 ACU
Networking.
• RS-232 to RS-485 ACUs, and RS-232 to
CoBox Master Ethernet converter.
The NexStar High Speed unit will support up to 8
Readers, 8 Keypads and 8 MIRO devices in an SNET multiplexing application. (All S-NET ports
must run at 9600 baud and are not user selectable.)
It will support up to 16 ACUs in any combination of
RS-485 and RS-232 wiring up to any limits
supported by a specific Host system. NSM and
StarGaze support up to 16 controllers on each poller
port.
NOTE: Each ACU needs its own Power Supply.
The NexStar should NOT be used to distribute
power. Current applications require 24-28VDC for
all ACUs and peripheral components.
