4.1 Definition of Intended Operational Environment
The NK823x Ethernet port system is an automation device that connects control
units for fire and intrusion with the Desigo CC management station.
Fig. 5: NK823x Interfaces
The NK8235 employs an industry standard MPC885 PowerPC CPU and is
composed of:
● Base board with power supply, CPU module, and basic configuration of
interfaces
● Optional add-on board with 2 RS232 ports (GND, Rx, Tx only)
The base board is equipped with:
● Power supply
● 2 serial interfaces (2 RS232/RS485)
● Dual Ethernet 10/100Base-T interface provides:
– BACnet/IP (UDP/IP)
– FTP (active/passive)
– SSH (putty console)
– Secure download (Feal 8)
– Monitor (custom encrypted protocol)
● MPC885 Power PC CPU module with:
– 64MB RAM
– 32MB flash EPROM disk
– Real-time clock (RTC)
– Linux operating system
– BACnet protocol stack
