the below message was from Eric some months ago.I have purchased the 4937 eval board and the PCI-DAS 4020.If anybody has a ciruit diagram on how to use the eval board for both the devices to do fm-demod, i would appreciate it.

thanks again

"The existing eval board requires +5, -5 and external inputs for the RF
and IF AGC controls (typically 1 to 4 volts).  I'd like to put a small
switcher on board the new eval board to handle the power, a dual trim
dac for the AGC controls that we can drive using the I2C bus that is
bit banged over the parallel port.  Also, I'd pick a different choice
of pins on the parallel port, because as is, it takes a bit of hair to
control the board from linux.  Reassigning some of the pins would make
this much easier."
