Information on the serial interface
• Via the serial interface on the device (RJ-11 jack), you can access the CLI of the device directly
via an RS-232 (115200 8N1) connection without assigning an IP address.
• Access to the device is also possible independent of the Ethernet ports.
• To connect the serial interface to the PC, you require a cable with an RJ-11 plug and 9-pin D-
sub female connector. The connecting cable for the serial interface ships with the device and
can also be ordered as a spare part.
