Summary DF8000 is a flexible I/O system designed for easy and cost-effective integration of a large spectrum of devices in a safety / security supervising centre. Based on an innovative modular approach, the DF8000 family is made up of DIN rail-mounted modules that can be combined in local units – distributed on RS485 lines – that can concentrate from 4 to 48 I/O points. Each DF8000 unit is composed of an intelligent module (CPU module) and by up to 6 input or output modules.

Bus Connectivity The DF8000 units communicate with NK8000 Ethernet Port gateways on RS485 using CMX-DL protocol. The RS485 port of NK82xx can be used for direct connection and any of the RS232 COM ports can also be connected as long as an RS232/RS485 converter is installed in-between. The converter can be powered by the same power supply of the DF8003 nearest to it, or by an independent power supply. The RS232/RS485 converter is not included in the DF8000 supply.

Configurations DF8000 is organised in units distributed on a RS485 line up to 1200 meters long. The communication protocol allows for a maximum of 16 addresses, and each unit can take one or two addresses depending on the I/O size. In more details, a DF8000 unit is made up of:  1 CPU module.  1 to 3 I/O modules: single unit, taking 1 of the 16 addresses on the RS485 bus. -- or -4 to 6 I/O modules: double unit, taking 2 consecutive addresses on the bus.
