Data interface
The bidirectional data interface is used to control connected devices, such as a
dome camera with a motorized lens. During setup the interface is used to connect
to the data terminal using the RS232 protocol.
The interface supports RS232, RS422 and RS485 transmission protocols.
The selection of controllable devices is growing constantly. The manufacturers of
this equipment can provide specific information on installation and control.
Warning!
Make use of the device documentation when installing and operating a
device to be controlled. It contains important safety instructions and
information about permitted uses.
Note
The transmission of transparent data is only possible when a connection
has been established.
