    Keyspan USA19HS reviews

    USA19HS USB to Serial Adapter (Mac/PC) is rated 4.7 out of 5 by 120.
    Rated 5 out of 5 by from Excellent Product Connecting to Fire Panels, etc. HIGHLY RECOMMENDED FOR CONNECTING TO FIRE PANELS!!! Our company deals in fire alarm panels and this is by far the best product we have ever used for downloading programs to panels and/or pulling out reports. This product was also recommended to us for use by Honeywell for the products we connect to. So far we have not had any issues with any of the ones we ordered. If you need to have a USB A to USB B to connect to specific panel types, the USB cable unplugs from the DB9 connector to allow it.

    Rated 1 out of 5 by from Great, except for Windows 10 I've used this adapter for years very successfully with WinXP and Win7. Works perfectly; five stars. But I cannot get it to work reliably with Windows 10; zero stars. Everything seems OK at first with Win10, but the adapter triggers a blue screen of death from time to time due to a problem in the driver. I can't live with that.

    Rated 4 out of 5 by from works on Mac OS-X 10.6, XP etc. On my MacBookPro with VMware Fusion, the device is working on both OS-X (native) and XP (VMware). On the Mac, you have to figure out with the serial assistant how to name the port. Next I worked smooth with SecureCRT. Then I upgraded to OS-X 10.7, waiting for the driver now...

    Rated 4 out of 5 by from Need OS X Lion support This is a great product but we really need that new driver for support under OS X Lion. I have a number of people who are holding off on purchasing the 19HS until then. The device is very reliable and performs well. Nice multi-platform support overall.

    Rated 5 out of 5 by from Works extremely well! I have used this product for over 5 years on both Windows XP and 7 without issue. I have used it to interface several RS232 devices. Make sure to have the driver installed, plug in the device and verify it is loaded in device manager before opening any other software that will use the com port it creates. Do this and you will not have any issues. Other devices I used would disconnect intermittently and fail to work requiring manual disconnecting and re-connecting, sometimes to a different USB port to get it to work. Not with this product, it has worked for hours at a time without issue.

    Rated 1 out of 5 by from Useless I purchased this as an adapter for my datalogger as per that manufacturer's suggestion. Unfortunately, the only thing this adapter was good for was frustration and wasted time. Following all the directions for installation and trying five different computers was no help. Neither was my phone call to the manufacturer as after troubleshooting by phone I was told that it 'could just be an individual malfunction.' With five different computers? I finally found a dusty old computer from my grad school days that had a port allowing me to connect directly to my datalogger without the Keyspan. So, the bottom line is that a dinosaur of a laptop was more useful than this adapter.

    Rated 5 out of 5 by from It works on 2007 iMac with OS X 10.10.2 I have a 2007 24 iMac and after many tries with other cables I finally found one that works . I been setting up my iMac for astronomy . I needed cable/s that work with apple products so this is the one! I'm using SkySafari 1.8 and wanted to operate my Celestron AVX mount , This cable did the trick . Also I have a Orion Auto guider and a Meade deep sky camera working too and it all works perfect ! THE only thing is the driver on the disk is a bit outdated and at 1st it didn't work , I went online to there site and downloaded / loaded the driver for my operating system and it worked perfect - finally I can operate the telescope from inside the house and NOT freeze ! perfect

    Rated 4 out of 5 by from Very Solid I've purchased this product for more than a decade. The Keyspan USA-19HS has worked well for the Macintosh user base I support. I have little confidence in the Mac drivers from other brands. I like the Type B connector and separate cord design. This design is solid and a smaller connector wouldn't hold up in the field. On that note- The original USB cord that Keyspan supplied was a thicker shielded type with clear outer jacket. A thinner black USB cord with less strain relief has been supplied with the currently shipping version from Tripplite. I still recommend this to other professionals without hesitation.
