Different Rate for input and output channels

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.
