Serial interface 
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.
