This plug-in utilizes the Google Charts API. You can view the various ECL settings here.
Essentially, the ECL code consists of two components: (1) the error correction level (L, M, Q, or H), and (2) the white border row/column width (1 - 40 rows, not pixels).
If omitted, the URL defaults to the current page/post url. You can also use any valid url or text (within the character limitation of the selected ECL attribute value).
When using an email address, a standard format is expected. For example email@example.com should be implemented as mailto:firstname.lastname@example.org.
Telephone numbers also have a standardized format. For example, 212-555-1212 should be implemented as tel:+12125551212.
An SMS link is encoded in a fashion similar to an email address. For example, a link to the number 12345 should be implemented as sms:12345.
These and many other possibilities are explained in detail here.
