Hence these parameters are still available when the DCU3 system is switched off and restarted again. For enabling the outputs of the DCU3 - system and of several system functions, which directly act on the fermentor system, 4 categories of switching-off or power failure, respectively, are differentiated: Switching „off“...

The settings preconfigured on delivery correspond with the fermentor system to which the DCU3 - system is assigned to.
Page 99: Connection Of External Devices
Operators Handbook DCU3 – System 9., Main function „Maintenance“ Connection of External Devices The DCU3 - system has, by default, 2 serial interfaces for the connection of external devices, such as printers, recorders, host computer, etc. The adjustments required for communication will be done in the function „External Systems“...
Page 100: Host Interface
Operators Handbook DCU3 – System 9., Main function „Maintenance“ Host Interface For communication with a host computer via the serial interface RS 422/485 or the Ethernet interface (HOST) the DCU system offers a flexible communication protocol. By means of the RS422 /485 or the Ethernet interface you can establish a bus system for communication with several DCU systems.
