b. Plug in the E12 and look for a new ttyUSBx, where x indicates the USB connection assigned (e.g., ttyUSB0).
If you had any other USB-serial devices plugged in, you may see more than just /dev/ttyUSB0, which is
why you should check for the presence of these devices first.
c. You can use any of a number of serial terminal programs to connect to your serial port. Linux versions of
PuTTy and TeraTerm exist and work the same way shown in the Windows examples above (other than
the name of the port to which you are connecting. additionally, utilities such as cu or screen are available
as well:
Using cu:
To connect:
sudo cu –l /dev/ttyUSB0 –s 115200
To disconnect, at the command line type ~. (tilde, period) and then press Enter.
Using screen:
To connect:
sudo screen /dev/ttyUSB0 115200
To disconnect, press
Ctrl-A
, and then
\
(backslash).
5. Using your terminal emulator, connect to the E12 using the following serial port settings:
l
115200 baud
l
8 bits
l
No parity
l
1 stop bit
l
No flow control
6. Use your terminal emulation window to log in to the E12 gateway.
Username:
snap
Password:
synapse
NOTE:
You must change your password the first time you log in. This prevents you from installing an E12
gateway with the default password set, which is pretty much the definition of a bad security idea. Ubuntu
enforces some restrictions on what constitutes a valid password, and these instructions are further defined
in the Ubuntu documentation available at
https://help.ubuntu.com/
.
7. Connect your E12 to the internet.
The easiest way to do this is to make a wired connection to a host (i.e., router) that supports DHCP. (Most do,
by default.) If you wish to configure your device for a static IP address, you may do so via the serial connection
before making your internet connection.
8. Update the Python Development Libraries
Before starting work with the E12, you'll want to make sure you have the latest versions of the software
installed on the unit. The E12 makes use of Python Development Libraries that are sometimes updated to add
