Subject: change cascading from 1024 to 2048 bins for each input channel 

Hello,

 
I want to ask whether it is possible to modify a Evaluation Board 5.0 from 1024 to 2048 cells for each of the 4 input channels.
On the rev50 manual at page 31 I found an option to connect the 4 unused channels by setting 8 solder bridges.
The source code for controlling the board seems already prepared for 2048 bins, since version 5.0.2.
 
So my first question: Are there any implementations in the VHDL Code to control the write shift register in 2048 mode? / Is there a necessity for a newer/other VHDL Code or is it already implemented?
 
And the second: Are there any other modifications except the eight zero Ohm resistors and maybe changes in the FPGA code?
 
My board info output:
 
Mezz. Board index:    0
DRS type:             DRS4
Board type:           9
Serial number:        2451
Firmware revision:    21260
 
 
Thanks a lot!
