Topcon GPS file help

I went out and shot a couple points to use for the college course I teach. When I came back to the office my computer crashed with my Topcon tools and Pinnacle on it. Can somebody convert these to rinex for me. And if possible solve the small network

Hey Guys, I recently acquired a Topcon QS, and in using it, i have noticed there is not an EDM setting, for reflective tape, like in the Sokkia's or Leica's.Ā 

Am I to make the assumption that i should use the "Prism" setting, and set the constant to 0
