2.11 NEXSTAR RS-485 MULTIPLEXER
The NexStar RS-485 Multiplexer provides a link between a WSE access control unit, such as the
Alto 818 or NexSentry, and multiple S-Net runs. With five symmetrical ports, the end-to-end S-
Net length can span up to 8000 feet (2400 meters) and contain up to 20,000 feet (6000 meters)
of installed wiring.
In the simplest configuration, the NexStar allows home-run wiring which eliminates excessively
long wire runs and the need to make multiple connections to a single terminal block
