As you may know, last year I began a Kickstarter project to create a low cost Micro PLC Training DVD.
As part of that effort, I was searching for a low cost USB to Serial Adaptor that individuals could buy which would also work with RSLinx's “Auto-Configure” feature.
Note: For a low cost version of the 1761-CBL-PM02 see this article
Keyspan USA-19HS: The World's Best USB to Serial Adaptor?
As can be seen below, it comes in an “easy to open” clear plastic clamshell package with the adaptor itself front and center:
The back of the package shows the included USB cable, and also includes the claim that this USB to Serial adaptor is the “world's best.”
Inside the package you'll find a driver CD with the notice that you need to install the software on the CD before you plug in your Keyspan adaptor.
So I inserted the CD into my laptop running Window 7 64 bit, and the software installation was friendly, quick and un-eventful:
Once the software install finished, I plugged the adaptor into my laptop. Windows seamlessly installed the hardware driver, and as can be seen below it was assigned to Comm 4:
With the cable driver installed and working, the next step was to test the cable out.
First, I connected the Keyspan adaptor to a 1761-CBL-PM02 which in turn was plugged into a MicroLogix 1000.
I then opened RSLinx Classic Lite, added a DF1 driver, assigned it to Comm 4, and pressed the “Auto-Configure” button.
For the final test, I used this adaptor to download a program to my MicroLogix 1000 and went online, all without issue.
So, if you're looking for a low cost USB to Serial adaptor cable that will work with RSLinx's “Auto-Configure” feature, after my hands-on testing I feel very comfortable recommending the Tripp Lite Keyspan USA-19HS .
