Average Reviews:
(More customer reviews)This item comes with absolutely no instructions for installation. The enclosed CD contained drivers to many products and was equally useless. I only found the correct driver after I called a company whose README file was on the CD who no doubt had many calls from others about the same product. The company had no affiliation with the actual product but they were kind enough to help me identify the item and I was then able to install a driver.
The unit does work properly now that the correct driver is installed but I don't envy the mere mortal that purchases this device. It is ridiculous that there are no instructions. So in an effort to help anyone that has purchased this device (or plans to purchase it) here are the instructions to install the driver.
When the unit is plugged in identifies itself as USB SER! The unit has a barely legible HL-340 molded on the side of the DB9 connector. HL-340 is the part number and with that you can find the driver installation executable (HL-340.exe) for the device under the folder USB-232 on the USB driver mini CD that comes with the device.
Don't expect to tell Windows to search the CD for the device driver - it won't find it because the driver installation is an .exe file that you need to run manually first. Simply run USB-232\HL-340\HL-340.exe first and then plug the device in.
After connecting the device, Windows will prompt you to install the driver. Follow the usual Windows prompts to install the driver software automatically (since the driver software was already installed on the system in the previous step). The driver identifies itself as USB Serial CH340 to add further confusion.
You will get warnings about the driver not having passed Windows Logo testing. You can ignore those warnings and install the driver anyway.
The com port should appear in the com port menus of whatever software that tries to use a com port - in my system it appeared as COM7 and this will probably vary on other systems.
Once the device is installed it works properly so I can't know it from that standpoint. It was just an ordeal to get it working. I hope that this helps someone.
