Information on the serial interface
● Via the serial interface (RJ-11 jack), you can access the CLI of the device directly via an
RS-232 connection (115200 8N1) 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. You can order the connecting cable for the serial interface
as an accessory.
