worked very well, stable and consistent
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.
Works well for our needs
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.
Behaves Like a Null-Modem Cable
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.
Thank you for taking the time to leave a review for our RS232EXTC1. We are sorry to hear that you experienced difficulty with our serial extender. Our Technical Advisors have reached out to troubleshoot with you.
