    Need Windows USB Driver for TENMA 72-13210 (electronic dc-load 30A/120V 300W)

    simonwahlmann

      Dear all,

      does anyone has an idea where to find the "windows usb-driver" for this device?

       

           TENMA 72-13210 (electronic dc-load 30A/120V 300W)

       

      It's not present on the attached original CD and I also couldn't find it anywhere in the internet.

       

      Thanks for your support!!!

       

      UPDATE 17th of Sep. 2018

      Thanks for your replies so far!!!

       

      The device is listed twice at "other devices" when I plug in the usb-port:

           - SZ KORAD USB Mode

          -  SZ KORAD USB Mode

       

      With a CD no driver but a list of commands to control the device is provided.

      There is also a Windows executable for a connection test. Its frontend shows three tabs, one for each communication port

           - Ethernet

           - RS232

           - USB

      The USB obviously didn't work, because the devices had no drivers installed.

      Using an rs232 to usb adapter I was able to control the device via the RS232 port. The device was then listed as "USB Serial Port (COM11)" with an FTDI driver being used.

      This might be a workaround but I need to decide whether or not to oder more of these devices. So an inusable usb-port will influence my decission.

       

      I tried out some random usb drivers ending up with an immediate system shutdown.

       

      What else could I try?

          This is quite similar to the Korad KEL-103, but even this model does not have drivers on its website and its manual makes no mention of the USB.

           

          When you connect it to the host, what kind of device is enumerated? Is it a standard USB-RS232 port from FTDI, Prolific or other?

           

          If nothing shows up, then it is possible the USB is either non-functional or fictitious.

            It would be good to know what the PID/VID combination of the USB device is. Under Windows, you can find this in the Device Manager in the properties for the Unknown Device under Details (Tab) / Hardware ID (Property). If you have Linux, it may even be better to run lsusb -vv and provide us the results.

             

            It could be a USB to Serial adapter as many lower-end units may have - depending on which chipset, you might need drivers from FTDI, Prolific, SiLabs, WinChipHead amongst others.

             

            If it is a "higher end" unit, it could actually be a USB Test and Measurement class device, which will need a VISA layer installed as the IVI driver comes bundled with the VISA layer. You could try National Instruments VISA (NI-VISA), although other VISA implementations are available (e.g. Keysight I/O Libraries, R&S VISA, Tek VISA, etc). Otherwise, it may be possible to use something like pyhon-usbtmc under Linux.

             

            Unfortunately, without further information such as a programming manual that lists the commands, their format and their values ... it's not going to be easy to get this to work. Ironically, you may end up learning more about the device if it has LXI-compatible LAN, which you can probably learn some details about the commands from. I wonder if there's even anything useful on the supplied CD - but not owning such a unit, I have no idea.

             

            Maybe if you could list the files on the CD, that could help as well.

                Well there are two different entries for each of the two devices:

                Device 1 "SZ KORAD USB Mode"

                     USB\VID_0416&PID_5011&REV_0200&MI_00

                     USB\VID_0416&PID_5011&MI_00

                 

                Device 2 "SZ KORAD USB Mode"

                     USB\VID_0416&PID_5011&REV_0200&MI_01

                     USB\VID_0416&PID_5011&MI_01

                    From some quick digging, it seems that the PID/VID belong to Winbond/Nuvoton and likely is a virtual COM port:

                     

                    0x0416    0x5011    Winbond Electronics Corp.  Virtual Com Port

                     

                    It doesn't seem drivers for this are available online - the only reference I found was this Chinese site which needs a login, but if it is USB CDC-class compliant, it should install automatically (similarly to Arduino Leonardo boards). Otherwise, it could be some very small .inf files on the CD-ROM that will be the appropriate drivers - if you can, could you list all the files/explore the CD-ROM? You can do that using the Command Prompt under Windows with the following command (assuming D: is your CD-ROM drive, creating a file called listing.txt in the current directory):
                    tree /f D: > listing.txt

                    and upload the list here?

                            It looks like mostly an old version of NI-VISA but hey - at least the 72-13210 Communication Commands with Computer.pdf and USB Driver installation.pdf look interesting. What do they tell you about installing the driver? I also suspect Test Command\72-13210.exe could be an installer bundle that contains a basic remote control application and driver bundled together (fingers crossed) so could be worth examining.

                             

                            Otherwise, do install NI-VISA (probably best from National Instruments directly for the latest/most stable version) and see if the IVI driver picks up your electronic load. If it does, then it will become a USB Test and Measurement Device (IVI) - from my machine:

                            While the CD does seem somewhat confusing, don't write it off just yet . Best of luck.

                                Thanks Gough,

                                well

                                1. NI LabView 2018 is already freshly installed including all updates an doesn't recognize the device at all.
                                2. The "USB Driver installation.pdf" is worthless, because it claims the driver would be on the CD but obviously isn't.
                                3. The executable "Test Command\72-13210.exe" is the test-program I metionned in the update of my question and is no installer but really just to test the connection sending the commands described in "72-13210 Communication Commands with Computer.pdf".

                                 

                                One thing I did recognize at second view of the "USB Driver installation.pdf" is that the driver should be a "nuvoton virtual com port" driver. This is visible on one of the screenshots. Also The OS of the given example is Windows XP. So all in all this is a quiet old description.

                                 

                                I managed to download such a driver from nuvoton as mentionned here

                                    What does Farnell's tech help say about this - they really ought to be able to come up with something.

                                     

                                    Are you able to try the LAN port ?

                                     

                                    A lot of things default to port 5025 for SCPI commands.

                                     

                                    If the load is any good it's pretty cheap even if you have to buy a USB <-> RS232 converter as well, although you really shouldn't have to.

                                      I have examined the drivers and they are as I expected - just basic INFs to get a USB CDC recognized with Windows' own usbser.sys driver. Unfortunately the ones there have NOT got your VID/PID pair covered, hence you probably don't see any difference with the install of the drivers as they won't be picked up.

                                       

                                      I've modified the inf to cover your VID/PID pair and uploaded the pair of files. Please unzip into a folder, head to the "Unknown Device" in Device Manager, choose to select driver manually/have disk from the location, then select the resulting device and install. Ignore any errors about signing issues with the driver (which may occur as I have modified the .inf). As I don't have the device in question, I have no idea whether this will or will not work, or whether it will even install, but it's worth a shot.

                                        Just had mine delivered today! Have you had any luck with USB drivers or LAN?

                                         

                                        The 72-13210.exe test tool doesn't discover the Load using the 'Network Debugger' tab, although I can Ping the IP address and get a response, so its on my network!

                                         

                                        Bit disappointed to be honest, my whole test setup is automated over LAN. USB I could have worked with, but when neither seem to work out of the box (and no real supporting documentation), its quite frustrating. I've currently got an FTDI USB to RS232 adapter on the serial port and testing things out that way.

                                         

                                        It doesn't respond to the LXI Discovery tool over LAN either.

                                         

                                        I contacted Element14 Support this morning and they said they would get back to me once that have spoken to the supplier regarding the USB Drivers. That was before I tried the LAN ... so, will be contacting them again later!

                                         

                                        VCOM Drivers posted by Gough Lui only address one of the listed Serial devices (SZ KORAD USB Mode) and whilst the 72-13210.exe test tool discovers one port, it doesn't connect. Also editing to add the other USB desciptor (%DESCRIPTION% = NuvotonCDC_DEV, USB\VID_0416&PID_5011&MI_00) which Gough missed results in an error loading the driver!

                                         

                                        Starting to feel like I should have spend a bit more and bought something else.

                                         

                                        UPDATE - 18/09/2018 @ 22:45 : Contacted Tech Support at Farnell (Element14) twice this morning, both time they said they would get back to me today .... NOTHING! Did find a USB driver that is supplied with KORAD PSU's (and re badge'd as the Velleman PS3005D). The CD for that PSU has the same USB Driver instructions and the DC Load and the CD has the 'USB Driver' folder with a single .INF file (NuvotonCDC.inf). There is no .CAT file, so it just references standards builtin Windows USB drivers. HOWEVER ! Still doesn't work. Still errors when you try and install a driver for the second 'SZ KORAD USB Mode' device. So, back to the drawing board and waiting for Tech support to respond !

                                            Ah how unfortunate ... I thought I might have been onto something ... so it comes up as two ports is a bit unusual.

                                             

                                            Normally you can work with test instruments over LAN just by addressing commands straight to Port 5025 (SCPI Direct). You could perhaps try using PuTTY configured in the Raw mode to see if you can get any result from an *IDN?

                                             

                                            You could also try talking over the available port using PuTTY in the Serial mode by putting COM4 (or whatever the port number is) and a sensible baud rate. Many USB CDC peripherals ignore this, so you might be safe to try 9600, 19200, 38400, 57600 or 115200 and see if you can get a response either.

                                             

                                            Barring no response either way, perhaps you might need to check the newline termination. Some devices need \r\n, others like \n only. Further to that, some devices have timing requirements (i.e. command has to be delivered in a single "burst" rather than being interactively typed in) - so perhaps copying and pasting the command in and seeing if it makes any difference.

                                             

                                            It is rather surprising how much trouble you're all having ... a product shouldn't be like this ... *shakes head*.

                                I've got a copy of the CD supplied with the KORAD KEL-103 (direct from KORAD support) and the 'USB driver' is under 'Software'. (Attached). Sadly, it doesn't do anything to improved the USB situation !!!

                                 

                                I've also queried why there are 2 devices shown in the device manager and why the LAN doesn't work with the Assistant application, still waiting on feedback.

                                 

                                Not heard anything from the 2 support chaps at Element14 that I reported the issues to yesterday and the day before! NOT IMPRESSED!

                                UPDATE 20/09/2018 @18:47 :

                                 

                                Hey, I discovered why the LAN discovery tool doesn't work! They discover the devices by broadcasting a UDP message with the string 'find_ka000' on port 18191.

                                 

                                However, they use the IP address of 255.255.255.255 as the broadcast address. THIS DOES NOT WORK! They need to work out the broadcast address from the hosts IP address (your computer) and the network mask.

                                 

                                Examples :

                                 

                                Host IP = 10.0.0.56, Mask = 255.255.255.0 -> The broadcast address = 10.0.0.255.

                                Host IP = 10.0.0.56, Mask = 255.255.0.0 -> The broadcast address = 10.0.255.255.

                                 

                                255.255.255.255 would only work if your network mask is 0.0.0.0.

                                 

                                The device then returns a UDP packet from each of the discovered device IP's to the host IP which contains a 48 byte long payload of...
