9.9 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. Each
DCU is separately addressed and can be directly triggered by the host computer. The RS422 interface
can also be used for peer-to-peer connection. In addition, a host computer can be connected via a se-
rial interface RS 232 (available via the peripheral interface PERI).
You must enable the data transmission between DCU and host system via the REMOTE
key of the DCU3 - system, see key pad at the front panel. During remote operation of the
DCU system the parameters of the assigned data groups can be changed manually.
