Where can I find 3D CAD drawings for UEI’s product?
Yes. UEI provides step files that you can download from our FTP site.
Where can I find the shipping weight for my system?
We have a list of product weights here on our website.
My system was delivered today. How do I get started?
Along with the hardware, you also received a Getting Started guide in your package. Please follow those instructions to install your development software (if applicable) and to connect your hardware. You can also find a series of Getting Started videos on our website (click here for videos, and select the Getting Started option in the Categories pull-down menu).
What are the RDY and STS lights for?
The RDY light indicates that the I/O board is powered up and ready for configuration and/or operation. For boards that need external power, RDY does not light until power is supplied.
For I/O boards that support mapped (RtDMAP, RtVMAP) or buffered (ACB) data acquisition modes, the STS light indicates that the board is in Operation mode (acquiring data or ready to acquire data).
How do I install new I/O boards? Can I rearrange I/O boards in my system?
You can install or rearrange I/O boards at your site:
Note that you must not perform maintenance while the chassis power is on. Hot-swapping will damage the board and possibly other boards in the system.
How do I find the IP address of my system if I don't know it?
The default IP address is 192.168.100.2 on NIC 1. If your system is no longer using the default and you don't know the IP address, you can connect a host PC to your UEI system via the serial port (57600/8/1/no parity), and enter the following to see the network configuration:
Alternatively, if you know the range of IP addresses your system could be, you can try PowerDNA Explorer. Set the network address range (Network > Address Ranges), and PowerDNA Explorer will attempt to connect to every IP in that range.
How do I check what version of software/firmware I am using?
For hosted PowerDNA systems, you can use PowerDNA Explorer to check versions:
For standalone UEIPAC systems, the SDK is installed in version-specific directories on your host, (e.g. /home/<usrname>/uei/ueipac-4.0.x). To check the version of the UEIPAC distribution on the UEIPAC itself, enter "devtbl" at the "#" Linux prompt.
I installed UEI's latest PowerDNA software recently. I'm seeing strange results.
You may have a mismatch of firmware and library software between your hardware and host PC. If you install a new revision of our software on your host PC, you must also install the latest firmware that is included with the download onto your system CPU board. You can do this through PowerDNA Explorer (Network >Update Firmware).
I’m getting strange readings when nothing is connected. What’s going on?
Floating input channels will read undefined values. To test inputs, use a known voltage and connect to input. Ensure a proper ground connection, as well.
Unused input channels before and after my driven channel are reporting some voltage. Is this expected?
Yes. You are most likely observing crosstalk. Multiplexed input boards, such as UEI’s AI-207, use a single ADC with each channel first going through a multiplexer. When the multiplexer switches to the next channel, there is some settling time before the reading stabilizes to the new value. If a channel has a high impedance (i.e. open circuit), then there’s no path for the stray capacitance of the input to dissipate power.
This is normal, expected behavior. It is not a problem by definition; the channels impacted are not connected to a signal to be measured. However, if you wish to eliminate this behavior, try the following:
Can I use the same boards in a military chassis? Is there any difference?
MIL chassis accept the same I/O boards as non-MIL chassis. Depending on your chassis type, you'll select DNA or DNR boards, which are electronically identical but differ in how they connect in the chassis. You use DNA boards in the DNA-MIL (or Cube-based PowerDNA / UEIPAC MIL systems) and DNR boards in the DNR-MIL (or RACK-based PowerDNA / UEIPAC MIL systems).
Will this new software release work on my older chassis?
Every time UEI releases a new software version, our highest priority is to maintain backward compatibility. If you have concerns, please contact UEI support at email@example.com.
I received a CD with the software, but I don't have a CD drive. Where can I get the software?
Please contact firstname.lastname@example.org for download links.
Can I run your UEIDAQ Framework libraries on my Linux Machine?
No, but programming in C/C++ with the PowerDNA API is portable to Linux as well as to the UEIPAC.
UEIDAQ Framework is Windows only.
Which acquisition mode should I be using for my application?
Our White Paper about UEI’s acquisition modes can help to identify which mode is the most appropriate for your application. If you’re unsure which mode to use please contact email@example.com and we’d be happy help!
What are the compatible power connectors for UEI RACKS and Cubes?
We recommend using the Molex 39-01-4040, which can be found here: http://www.digikey.com/product-detail/en/0039014040/WM18435-ND/300068
You’ll also need the female pins (4 per) for the connector (Part# 44476-3112): http://www.digikey.com/product-search/en?vendor=0&keywords=44476-3112
