VXI-AO-48XDC Module
The VXI-AO-48XDC programming model is very similar to the
AO-2DC device. Any function or VI valid for the AO-2DC is also valid
for the VXI-AO-48XDC. Furthermore, the
Set_DAQ_Device_Info
function and the AO Parameter VI provide support for changing this
device’s power-on state. Additional information is available in the
NI-DAQ Function Reference Manual for PC Compatibles.
Set_DAQ_Device_Info
The following example shows how to use this function to save the current
values of the voltage and current channels as the power-on values:
status = Set_DAQ_Device_Info(device,
ND_AO48XDC_SET_POWERUP_STATE, ND_NODE);
AO Parameter VI
• You can use the Save power-on state option to save the current
values of the voltage and current channels as the power-on values.
Common Questions
1. When I attempt to save my configuration in the NI-DAQ
Configuration Utility, I receive a dialog box that says The device
is not responding to the selected base address. What does this
mean?
If you followed the steps in the Software Installation and
Configuration sections of these release notes and you get this
message, most likely it means that an incorrect VXI Logical Address
is specified. Please verify that the displayed logical address matches
the logical address set by the device DIP switch. Additionally, it may
mean that you have forgotten to run
RESMAN.
With the VXI-MIO boards, another possibility is that your EEPROM
may be incorrect. The VXI-MIO boards need at least 4 KB of VXI
address space to function properly. Check the amount of space your
board is requesting by launching
VXIEDIT and selecting your
VXI-MIO from the list of available boards. If the address size is less
than 4 KB (0X1000 B), repair your EEPROM.
