Help w/PulseTrain and PulseCounter using Mizar 8310 board

[Tien Doan <tdoan@vivanet.com>]

I'm trying to use the Mizar 8310 board for pulse width modulation and for 
tracking a frequency-modulated signal.  The device drivers I'm using are
the ones that came with EPICS r3.11.4.  My question are:

1.  the 8310 has 24 frequency output modes.  How do I put the board into 
the different frequency generation modes ?  is there a field in the 
PulseTrain block that would allow me to do this ?

2.  how do I use the pulseCounter block to track the FM signal ?  Do I
need to call the pulseCounter block every X sec, read the counter, 
then reset and restart the counter ?

thank you
