American Power Conversion's Isolated Extension Cable is a device that allows you to lengthen the communications connection between a server running PowerChute software and an APC uninterruptible power supply (UPS). When standard cables are used for distances of more than 5 meters, communications can become unreliable and ground loops can damage computer serial ports. If your facility uses large APC UPSs (Matrix-UPS or the Symmetra PowerArray, for example), it may not be practical to place the server running PowerChute software close enough to use the standard data cables. With the Isolated Extension Cable, you can house a UPS in one location and monitor it up to 100 meters away.
