4)  Plugging in the adapter board: 

See figure 3 for alignment.   The QF4A512 programming adapter should be pushed down evenly not at an angle.  
Note, by adding the 3 additional headers to the development board signals will be brought up to the programming 
adapter board through J1-J4.  See below. 
 

Adding the three additional 

headers brings the signals from the 

BNC connectors up to the 

programming adapter board.

Note:  R2,R6,R11,R15 

create the single 

ended configuration 

for the PA board and 

development board

Align the programming 

board as shown when 

plugging it into the 

development board

5)  Input level and protection scheme: 

The QF4A512 programming adapter is DC coupled with input voltage protection only.  With no modifications the 
largest signal is 2Vpp AC coupled.   Voltages larger than 3.0V will activate the internal protection diodes which are 
series limited with 100ohms.  These resistors can be changed to simulate the target system including a spot to add 
AC coupling.    

 

6) Programming example: 

 
Step 1:   Plug in the USB cable to the development board.  Make sure the programming adapter board is powered 
              either from the development board or through the AC Adapter plugged into CN4.
