E-1608

An anti-aliasing filter is used to satisfy the Nyquist theorem over a specific bandwidth. In some but not all cases an anti-aliasing filter is not required. By choosing a sampling rate that is at least twice (5 to 10 times recommended) the maximum frequency of your signal you can achieve your sought after results. Measurement Computing does offer several DAQ devices with built in filtering. Please email us at info@mccdaq.com for details on these products.

The E-1608 has one A/D converter that is shared amongst the channels. When 1 channel is sampled, the maximum sample rate is 250 kS/s. If all 8 channels are sampled, the maximum sample rate is 31.25 kS/s per channel.

The E-1608 model does not have a timer output channel. This is a feature on some of our USB models, such as the USB-1608G. For those USB models, the DLL function to call is PulseOutStart()

MCC strives to make the UL as easy to migrate between hardware models as possible, but there are sometimes differences in hardware models that require code changes. You should to check to see which UL error code number(s), and from which functions, your code generates when run on the newer hardware. Then look those errors up in the ULHELP file. Also search on each hardware model in the ULHELP file, to see a list of compatible functions and parameters. Comparing the lists for your two models reveals that the analog output differs as follows: The E-1608 cannot use the AOutScan function in clocked mode (you cannot specify a clock rate). The AOut function (software paced) can be used. Try example program ULAO01

I am pleased to inform you that Measurement Computing has recently released Python support for MCC DAQ products. Included in this release is support for Ethernet based DAQ as well. Here is a link to a list of all supported MCC DAQ hardware. https://www.mccdaq.com/pdfs/manuals/PyWin-hw.pdf Please contact Sales Engineering at 1-800-234-4232 Ext-3 with any questions you may have.

The input range is selected in the higher level software program, which in your case, is LabVIEW via our ULx driver. The ULx Create Virtual Channel VI has two inputs that indirectly select the range for you. The two inputs are Minimum Value and Maximum Value. You choose these two values based on your signal/sensor’s analog output range, and then ULx picks the best DAQ hardware input range that can accommodate it.

Header connector W2 provides connections to the digital I/O, the trigger and external clock as well as the power output and digital grounds. Header W4 provides connections to the analog inputs, outputs and analog grounds. The headers are used in place of the screw terminals for accessing the I/O on the E-1608-OEM version. Please refer to page 27 of the User’s Guide for header and screw terminal pin designations. http://www.mccdaq.com/PDFs/manuals/E-1608-OEM.pdf

It sounds as if you had an older version of InstaCal and/or a UL-based application program previously on the PC, and there is a version mismatch or duplicate files. The following FAQ discusses 2 specific causes and solutions to what you describe: InstaCal seeing the DAQ hardware, but another application (such as TracerDAQ or a LabVIEW app) not seeing the hardware. http://kb.mccdaq.com/KnowledgebaseArticle50403.aspx If you still have the issue, be sure to contact our Tech Support folks, who can help you resolve it.

Hello - Thank you for your feedback. Unfortunately at this time, we do not have 3D models available for our DAQ products. I have passed on your feedback to the Engineering team.

Hello Alex, Measurement Computing recognizes the importance of having Linux support. We have started the process for the development of an E-1608 Linux driver. As for new product development, yes there is dialog taking place for expanding the Ethernet product line.

Yes, the E-1608 is supported by our latest release of the Universal Library. I also checked the latest revision of the UL Help to make sure the E-1608 was included and currently all supported hardware including the E-1608 is listed in our Help files. The latest revision for our UL Help (as of 6/17/2015) is rev 20 which was released in December of 2014. You can check what revision you have at the bottom of the UL Help’s cover page. If you need to update your Help file I would recommend that you download the latest MCC DAQ CD from http://www.mccdaq.com/software.aspx

Hello Fernando - The E-1608 was introduced on January 21, 2015. We are investigating developing additional Ethernet DAQ devices. Thank you for weighing in on a 24 bit analog AI/AO type device

The most common method for using the E-1608 is wirelessly via the tablet/smartphone’s existing Wi-Fi access. The E-1608 would connect to your network via CAT-6 Ethernet cable. While less common, you could instead use a third-party USB to Ethernet dongle for a hard-wired connection. As for discovery, if the E-1608 is connected to the same subnet (wired or wireless), the discovery of the E-1608 is automatic. If not connected to the same subnet, we provide a manual method for discovering the E-1608 by inputting the IP address for the E-1608.

There are a couple of projects on Github that work great with native Python access to these devices. I use this code to talk natively to MC devices using Ubuntu Server 14.04 without the need for IronPython or using MC libraries etc. Small, clean and fast.

Sorry, but we do not have examples for a “headless” Linux application. Our current library support for the E-1608 consists of a programming API for C®, C++®, C#®, Visual Basic®, and Visual Basic® .NET™ using Visual Studio® http://www.mccdaq.com/daq-software/universal-library.aspx and our Universal Library for Android (JAVA) http://www.mccdaq.com/daq-software/universal-library-android.aspx
