DSM-050: BACnet Router

Description
The DSM-050 is a fully programmable, Native BACnet™ Building Controller that routes network traffic between BACnet IP, BACnet over Ethernet, BACnet MS/TP, and BACnet PTP. The DSM-050 comes with a 10-BaseT Ethernet network card, one RS-485 Port, two RS-232 ports, real-time clock and battery backup.

Features
—Native BACnet IP, BACnet over Ethernet,

BACnet MS/TP and BACnet PTP

—Controller firmware stored in flash memory for easy upgrade

—Database memory expandable from 256 to 1256 KB (SRAM)

—Derived Network Addressing (DNA) for simple integration into a standard network architecture

Application
The DSM-050 is intended for use as an external point of connection to a building using BACnet IP. It may also be used for interconnecting different BACnet networks within a building.
