we had a cat 5 run over 500 ft that ran from our hospitality front desk serial interface to the restaurant point of sale server, easy to install, i did use the power adapters as it was convenient to do so... worked very well, as advertised, would use it again.

worked very well, stable and consistent

startech.com

The extender was purchased to control a camera on a tower outside our broadcast facility.  The cable run was over 500' from the Control Room to the top of the tower.  Installation was easy and the extender works great.

Works well for our needs

Lukas

Be advised that this serial extender behaves like a null-modem cable and carries only the CTS and RTS signals in addition to transmit and receive.  The included null-modem cable can be used to effectively reverse the null-modem behavior, but that is not at all intuitive.  The extender seemed to work fine once I understood the behavior, but I wasted quite a bit of time getting to that point.  It would be best if StarTech made the behavior clear in both their marketing materials and their manual, which is the main reason for my rating.

Behaves Like a Null-Modem Cable

We needed the product to work @ 57600 Baud and we simply didn't get near there! I tested it @ 9600, 19200, 38400, and 57600 Baud on a 256 ft Cat 5 cable. Only 9600 & 19200 worked successfully.

Not that great!
