Hi, all!
I have NI-6229 DAQ board. The specification is here:
>> daq.getDevices
ans =
ni: National Instruments PCI-6229 (Device ID: 'Dev2')
Analog input subsystem supports:
4 ranges supported
Rates from 0.1 to 250000.0 scans/sec
32 channels ('ai0' - 'ai31')
'Voltage' measurement type
Analog output subsystem supports:
-10 to +10 Volts range
Rates from 0.1 to 833333.3 scans/sec
4 channels ('ao0','ao1','ao2','ao3')
'Voltage' measurement type
Digital subsystem supports:
Rates from 0.1 to 1000000.0 scans/sec
48 channels ('port0/line0' - 'port2/line7')
'InputOnly','OutputOnly','Bidirectional' measurement types
Counter input subsystem supports:
Rates from 0.1 to 80000000.0 scans/sec
2 channels ('ctr0','ctr1')
'EdgeCount','PulseWidth','Frequency','Position' measurement types
Counter output subsystem supports:
Rates from 0.1 to 80000000.0 scans/sec
2 channels ('ctr0','ctr1')
'PulseGeneration' measurement type

I whant to use different Rate for input channels (250000.0 scans/sec) and for output (833333.3 scans/sec). How can I setup this?
This code:
mydaq = daq.createSession('ni');
addAnalogOutputChannel(mydaq, 'dev2', 0:1, 'Voltage')
rate = 833333.3;
mydaq.Rate = rate;
setup the Rate for both channels.
