Version 1.14 of 9th April 2008

Bug-Fix for V13: channels are interchanged at high sampling rates very seldomly

Version 1.13 of 27th February 2008

Bug-Fix: M2i.70xx and M2i.72xx: when doing bit mode output (1, 2 or 4 bit) the system hangs. Bug came with version V12

Version 1.12 of 27th January 2008

Bug-Fix: sometimes timeout when using very slow sampling rate (<< 100 kS/s)
Bug-Fix: last bugs of oversampling mode eleminated
Bug-Fix: trigger delay between synchronized cards

Version 1.11 of 18th September 2007

Lenght of continuous marker output (generator cards) increased. Is now 1/2 of memory size up to 255 samples
Support of Extra FIFO polling mode added, single access to timestamp and ABA data
Delay between cards of different type running with same speed reworked -> zero delay between cards now
Bug-Fix: extremly seldom wrong data in timestamp FIFO starting with 0x80000000

Version 1.10 of 27th April 2007

Output FIFO buffer size in hardware programmable to reduce latency on data change
Bug-Fix: pulsewidth trigger for channels on module B didn't work properly all the time
Bug-Fix: TTL trigger didn't work on settings with very small pre-trigger size
Bug-Fix: very seldom channel data swapping on output cards
Data timing improved

Version 1.09 of 20th December 2006

internal use only

Version 1.08 of 1st December 2006

Support of new Star-Hub hardware version V2
Bug-Fix: trigger delay on modules with 4 or 8 analog channels fixed
Bug-Fix: some star-hub trigger combination didn't work properly

Version 1.07 of 30th October 2006

Support of Star-Hub option added
Bug-Fix: Force trigger sometimes didn't work on slow sampling rates

Version 1.06 of 30th August 2006

Support of output modes added
Support of bit modes (7005) added

Version 1.05 of 18th July 2006

Bug-Fix: force trigger didn't work with very slow sampling clocks
Trigger output can be programmed at Multiple Recording to either output one large trigger signal or one trigger pulse on every segment trigger
Bug-Fix: some timing problems between base card and module solved

Version 1.04 of 6th July 2006

Support of digital cards added
Force trigger now emerges single trigger events for Multiple Recording
Support of 2 GByte and 4 GByte memory finished

Version 1.03 of 27th June 2006

BaseXIO option added to firmware including asynchronous I/O, additional trigger, timestamp reference clock and additonal timestamp inputs. This option needs to be ordered seperately
Bug-Fix for Multiple Recording Mode/Gated Sampling mode: some trigger events not detected

Version 1.02 of 1st June 2006

Bug-Fix: card didn't start properly when sampling rate below 400 kS/s
Added some functionality for M2i.31xx series
Bug-Fix: Timestamp counter stopped between acquistions

Version 1.01 of 10th April 2006

first version delivered to customers
