## Customer Reviews

### ⭐⭐⭐⭐⭐ This device is excellent and works as well as much more expensive units
*by S***R on April 10, 2015*

This device is excellent and works as well as more expensive units. Comes with a driver DVD or the latest version driver can be downloaded from the IO Crest website. Provides 8 serial port tail cables using standard 9 pin female connectors. Only slight drawback is the 8 tails are slightly heavy in my estimation and should have some type of strain relief. I ty-wrapped the cable to the cabinet to provide relief on the multi-point connector. Regardless, it iss still an excellent purchase for the price.

### ⭐⭐⭐⭐ Worth it for those who need a lot of serial connectivity
*by L***F on June 30, 2018*

Works pretty well. Using this in a 2U server to connect with multiple other servers and UPS.I had some difficulties getting this to work in Linux (Debian) but got it running after some tweaking. Incredibly nice to centralize connectivity and be able to write custom code on that server to interact with the full infrastructureUsing this primarily to allow for SSH and issuing commands to multiple servers with ease

### ⭐⭐⭐⭐⭐ Trouble-free under Windows 10
*by G***N on August 18, 2016*

No issues with Windows 10. Plugged it into an open video card slot (PCIe 16X). Hand-installed the drivers supplied on the CD for the Exar chip. For once, the COM port numbering was in the correct order, consistent with the numbers stamped on the connectors. Worked with an application that had been having fits with other boards.
