Personal ServSwitch 2 Port Product Information The ServSwitch Wizard is designed to be used on desktops and to look great there. But it's not just for show - it's a sophisticated switch that can support display data channel (DDC) PC-to-monitor communication and its firmware can be flash-upgraded. Two or more Wizards can be synchronized to support CPUs with multiple video outputs. CPU connections are made through standard PC-style connectors. The Wizards have built-in variable scanning and support extended-distance CPU connections. Because power is drawn from connected CPUs, you do not need external power supply. If, however, the CPUs do not provide enough power for the switch to operate reliably, you'll need the 5-V Power Supply. Connectors interfaces 1 x management - RS-232 - 9-pin D-Sub (DB-9), 2 x display / video - VGA - 15 pin HD D-Sub (HD-15), 2x keyboard - generic - 6 pin mini-DIN (PS / 2 style), 2 x mouse - generic - 6 pin mini-DIN (PS / 2 style)
