NexWatch NEXSTAR S-Net Multiplexer
NEXSTAR is a 5-port RS-485 multiplexer that provides a link between a
NexWatch access control unit and multiple RS-485 runs. NexStar allows
home run wiring to connect between RS-485 communication devices and a
controller.
When used with NexLine adaptors, the NexWatch NexStar S-Net
Multiplexer provides a simple and inexpensive way to use existing
coaxial wiring in a digital access control system. This allows use of
digital readers and other RS-485 devices. NexStar also provides an
inexpensive solution for upgrading systems with Wiegand wiring schemes
to RS-485 protocol. The RS-485 transceivers are removable to facilitate
port isolation during system troubleshooting and support for plug-in
RS-232 modules. With the optional RS-232 adapter installed, the NexWatch
NexStar S-Net Multiplexer becomes a Half Duplex RS-232 to RS-485
converter.
NexWatch NEXSTAR S-Net Multiplexer Key Features:
Four S-Net ports for star configuration wiring to readers and one
port for multiplexing to a controller
Facilitates installation and/or upgrade by allowing several different
wiring options with NexWatch's advanced digital controller and
components
Phoenix connectors allow easy wiring
Built-in termination
Reliable transfer of data
Allows increased wiring range by offering home-run connectability,
while still providing multi-drop capability
Each RS-485 transceiver supports up to 16 S-net devices per port
LED indicators for each RS-485 port provide status on communications
activities
Removable (socketed) RS-485 transceiver chips for ease in
troubleshooting
Minimizes costly daisy-chain requirements while improving power and
signal distribution efficiency over daisy chain links
Allows a high level communication protocol
(S-Net), yielding better
performance
UL-294 listed access control system component
