NexStar™ S-Net Multiplexer 

NexStar™ S-Net Multiplexer 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.

Overview

NexStar™ S-Net Multiplexer 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:
  • Maximum flexibility for wiring RS-485 communications in an installation through multi-drop connections
  • Network wiring lengths up to 20,000 feet
  • Conversion path from analog technology to digital technology. Using Honeywell’s NexLine™ adapters, existing coax can be used in a digital system
  • Upgrade path for Wiegand style networks to RS-485 using the existing twisted-pair wiring
  • Phoenix connectors allow easy wiring
  • Built-in termination
  • Reliable transfer of data
  • Allows increased wiring range by offering home-run connect ability, while still providing multi-drop capability
