One thing you might check is your convert rates. I know there was a
change between Trad DAQ and DAQmx on the convert rates. Since you are
using an external clock I am not sure if it will matter or not, but
make sure these are the same in your applications.

Dave...there shouldn't be any reason why you couldn't do this with the
16E-1 adn the BNC-2110. On the 2110 there is a BNC for counter0
output. You need to wire this into User1 BNC and wire that to PFI4
which is the gate of counter1. Then you can wire your trigger into
PFI0 which is also a BNC
What I believe you want to do is a retriggerable pulse train
generation (this is assuming the pulse is a consistent frequency/duty
cycle when on). There is a DAQmx example called multi-function Ctr
Retrigg Pulse Train Generation for AI Sample clock which should give
you a good starting point
