Connecting to JeVois using serial-over-USB: Mac host

Finding the serial-over-USB device on Mac host

When the JeVois smart camera is connected to a Mac OSX host, a new serial-over-USB is automatically detected. Its name is of the form:


where the XXXX characters shown above are replaced by a 4-digit number that depends on yoru exact Mac computer.

To find out the exact name on your machine, open a Terminal window (in Applications and then Utilities), and type:

ls /dev/tty.usbmodem*

which should return the device name.

Using the screen command

You can use the built-in screen program to connect to your JeVois camera:

screen /dev/tty.usbmodemXXXX 115200

where you replace XXXX by the number that was returned by the ls command above.

Once you are connected, you can issue commands such as help, info, etc

The screen program does not (as far as we know) provide an option for command echo (to see what you are typing). Hence, as you type, you will not see what you type. This is normal.
To scroll up while using screen, type CTRL-A ESC and you can then use the arrow keys or mouse wheel to scroll up. Type RETURN twice when you are ready to go back to interactive mode.

Using other serial terminal programs

Other programs are available for Mac which are more user-friendly than screen. For example, we have had good success with ZOC 7.
