NexStar S-Net Multiplexer

The NexStar is a 5-port RS-485 multiplexer that provides a link between a NexSentry access control unit and multiple RS-485 runs.

Overview

The NexStar is a 5-port RS-485 multiplexer that provides a link between a NexSentry 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 adapters, NexStar 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 NexStar becomes a Half Duplex RS-232 to RS-485 converter.

Features & Benefits:
  • 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 Honeywell’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
Certifications:
  • UL 294
