Options & Ordering - S4 OPEN BACnet-N2 Installation And Operation Manual

OPTIONS & ORDERING
How many devices?
The number of N2 devices determines the size of the router you will need. Choose from 16, 32, 64,
128, or 253 (256, with 3 addresses reserved by Metasys®).
How many Downstream interfaces?
Every S4 Open appliance comes with one downstream interface enabled by default. The
Downstream Adapter provides an easy way to connect legacy Metasys® N2 buses to S4 Open
appliances, without any wiring changes to either system. Simply disconnect the legacy bus from the
controller, plug it into the S4 Open Appliance and rapidly begin the integration process. You may
choose to enable one or two additional downstream ports, depending on your needs.
Upstream connectivity?
Upstream capability is available as an option on all S4 Open appliances, and comes with the full-size
(256) router by default. Upstream connectivity provides an easy way to connect a legacy Metasys®
supervisory controller to an S4 Open appliance. The installer simply disconnects the legacy bus from
the supervisory controller, plugs the Upstream Cable into the supervisory controller, and continues on
with the integration process.
System Bundles
S4 Open appliances are sold as system bundles, which means they come complete with power
supply and all necessary cables and adapters, as well as the support CD and Quick Start guide.
All of the information above is represented in our product numbering system.
