I think that you will only find the channel that the box is tuned to.
But, once again, you have avoided the question, what is the box
producing? Analog or digital signal?
My box from RCN takes a coax in from the "wall" and sends a coax to my
analog TV. The output is an NTSC signal on channel 3. When I tune my
TV to channel 3, I can watch whatever channel the cable box is tuned to
watch.
What are you expecting your cable box to produce for output?

Using how?

I know the cable box will let you watch cable TV, that's its purpose.
It will succeed when you have everything cabled up correctly. We're in
the process of getting you set up correctly.
I feel a little bit like the hologram in "I, Robot". My programming is
limited, you will have to ask the right questions.

I would start by plugging the cable from the wall directly into you
turner card and do a channel scan. That will tell you what unencrypted
on your cable that can be tuned directly.
wall <==coax==> tuner card
If you wish to view/record any of the encrypted channels, you will need
to change your setup to include your convertor box.
wall <==coax==> converter-box <==coax==> tuner
In the second case, your tuner card will only see what the convertor
presents to it (it does *not* un-encrypt everything at once, it only
un-encrypts the single channel it is tuned to, and only if it beleives
you are subscribed to receive that channel). It will send to your TV
(or in this case your tuner card) only the channel that it is tuned to.
How it sends that channel depends on how it was designed. If its like
my convertor box, it'll send it on NTSC channel 3 (or 4, sometimes they
have a switch in the back to be able to select which). Other more
modern boxes might have a component-out which can be fed directly into
your (newer) digital TV. I haven't seen a convertor box which outputs
an ATSC signal (they may exist, I haven't seen one). So, if you are
doing this setup, you need to know how to configure your tuner card to
properly receive the signal from your convertor box.
Does this make sense?
