  • "Thank you very much. The ST-C5USBVA-300 has taken care of our problem, and that is a big relief for our hospital.

    We have a Xmark tracking and monitoring product called The Hugs Infant Protection System for the healthcare and security markets. It is a Windows based system that constantly monitors the location of infants via an electronic tag and all exits from the department.

    This computer system as with any computer system has to have parts, keyboards, etc. replaced from time to time. In our case the computer chassis is in a locked box, hidden away from sight and only the mouse, keyboard, display and audio components are at the nurses station for security. Password protected as well. We had a new USB mouse and keyboard attached to our system via a separate USB extender which caused a lot of intermittent problems, such as computer lock-up, especially after long periods of inactivity. After trying various configurations to no avail, I started researching for new and different manufacturers of a USB KVM + Audio Extender set to simplify and eliminate our problem. NTI's description of their unit had a statement of 'Keep-alive keyboard/mouse emulation for flawless operation' which piqued my curiosity. After talking with a NTI representative about our situation, we decided to try this unit.

    We have the ST-C5USBVA-300 in and working, and have not had any more intermittent problems. Our security officer is pleased, as is the nursing staff."
