Question

how 74192 counters can count from 11 to 31?( of course two counters can do that but i want to know the way of connections between the counters?)

Answer 1

Look at the block diagram on this page: http://www.kpsec.freeuk.com/components/74series.htm#74192

The IC has a preset that must be set by placing a low_clock signal while applying high_clock signals to the Qa and Qd inputs. Once the counter reaches 31 you'll have to have those outputs configured to send either a preset or reset signal.
