S2N2D Gateway
N2 to Douglas Lighting Gateway

This Product Has Been Discontinued
 
However, a replacement Device is currently
being developed for Release in Late Summer of 2010.  Interested parties can contact our Sales Department for details.
 
 
Overview  
The S2N2D Gateway bridges the connection between the Johnson Controls N2 Network Bus (N2 Bus) and the Douglas Power WRS-2224 Lighting Scanner Network Bus (DP Bus).  This device allows Douglas Power WRS-2224 Lighting Scanners (with the WR-ASCII Network Module) to be controlled (individual relays and groups/zones) by the Johnson Controls Metasys system.
 
 
The S2N2D Gateway is connected to both the N2 and DP busses with separate connections to each.  The S2N2D Gateway appears as a slave to the N2 Bus (N2 VND Device), and simultaneously appears as a master to the DP bus.  The actual Douglas Power Lighting Scanners appear as N2 bus slaves to the N2 Bus through the S2N2D gateway.  The N2 Addresses of the DP Scanners are the mapped to the addresses selected on the DP WR-ASCII Network Module.
 

The Douglas Power Scanner’s relays and groups/zones appear as Binary Input and Binary Output objects to the Johnson Controls Metasys system.  The Johnson Controls Metasys Point Map of the system is given in the S2N2D Data Sheet.
