1) Can PCI-1200 be replaced with PCI-6221?
Yes it can be, in hardware functionality and performance terms, M series will exceed the PCI 1200
2) Can PCI-6221 mix with other 3 PCI-1200?
3) Will there be any problem?
The major problem I can think of is the driver incompatibility between the two devices
PCI 1200 has only Traditional DAQ driver support ( 6.9.3 or lower)
Whereas PCI 6221, is supported only by DAQmx and does not support Traditional DAQ device drivers
Also, If you are usingWindows NT, PCI 6211 will require NT Service Pack 6 or greater.
So if you have an application program running, you will have to modify it for your PCI 6221.
Hope this helps

Dev
