Troubleshooting
There are two known problems which will prevent WinWCP from recording from a Digidata 1200’s analog input
channels.
I/O port conflict. The Digidata 1200 default I/O port addresses span the range 320H-33AH. These settings conflict with
the default MIDI port setting (330H) of Creative Labs. Sound-Blaster 16 and similar sound cards. There are a number of
solutions to this problem.
1) Change the Sound-Blaster MIDI port setting to a value higher than 33AH.
2) Remove the Sound-Blaster card (or disable it using the BIOS setup if it is built in to the computer motherboard).
DMA channel conflicts. WinWCP requires DMA channels 5 and 7 to support the transfer of data to/from PC memory
and the Digidata 1200. Many sound cards also make use of DMA 5 and can interfere with the operation of the Digidata
