 One needs to realize that the readout time, for each subframe is 10.5~$\mu$s if the detector is in parallel mode. 500~$\mu$s if the detector is in non parallel mode. Note that in {\tt{dr 32}}, as the single frame readout from the chip is 500~$\mu$s, no {\tt{subexptime}}$<$500~$\mu$s can be set in {\tt{parallel}} mode. To have smaller {\tt{subexptime}}, you need the {\tt{nonparallel}} mode, although this will have a larger deadtime than the acquisition time.\\
 
-Online rate corrections can be activated. They are particularly useful and implemented \textbf{only} in the autosumming mode, i.e. when {\tt{dr 32}} is activated as  every single subframe is corrected before summing it. To correct for rate, the subframe duration has to be known to the correction algorithm.

 do the same for the other boards. You can program in parallel many boards, but you cannot load two bitfiles on the same board till loading and copying one process has finished. So load all left febs together, then proceed to the right febs, then the bebs. Power off completely everything. Power it on.
 
 \section{Pulsing the detector}
-\begin{description}
+Thre are two ways to pulse the detector: 
-\item [pulsechip n] sets the chip into test mode with \textit{resmat} = 0 and \textit{externalenable} =1.  Pulses chip by togglying the enable n number of times. The acquire is then done with no pixel matrix reset before the acquisition. If n$=-1$, the chip will be set into normal mode. This is necessary to restore normal chip operations after the test.
+\begin{itemize}
-\item[pulse n x y] Pulses pixel at coordinates (x,y) n number of times. 
+\item \textbf{Pulse digitally:} when you are interested to the output readout and do not care about the analog response from the pixels:
-\item[pulsenmove n x y] Pulses pixel n number of times and moves relatively by x value (x axis) and y value (y axis)
