This compact extender means that you can use standard, low cost CAT5e/6 cable to extend a standard PS/2 keyboard & mouse at distances of up to 100m. Simple to install, the extender consists of a local transmitter unit which connects to your computer & a remote unit for connection to your keyboard & mouse. The extender uses balun technology to convert PS/2 signals for use over patch cables, or your structured cabling system. Typical applications include operating computers from within non-secure environments (use in conjunction with our VGA extenders). Please note:CAT5e/6 cable is not included with this product & must be purchased separately.
