Logging from UART

To connect to the device terminal via UART, use the RJ45-RS232(m) and RS232
(f) USB to connect to the UART management port, in the front panel of the WR-
ZEN as shown in the
The recommended software to manage UART connections on Linux is picocom,
which you should be able to install just by running with super user privileges:
sudo apt install picocom
Once installed, the command to establish the connection with picocom is similar
to:
picocom –b 115200 /dev/ttyUSB<X>
where ttyUSB<x> corresponds to the instance of the USB-UART driver. In most
of the case, it will be ttyUSB0 (e.g., only one USB-UART cable connected to the
PC) and the expected output is as follows

Retrieve the IP address assigned to the device using UART or by scan-
ning the local network.
Note: DHCP IP address: The assigned IP should persist

after every bootup.
Connect the device using UART (see
page 26).
Follow the steps described in network configuration from CLI (see

Reboot the device.
Connect eth0 or eth1 (according to the user network configuration).
