USB & VGA KVM extender
dataCat vu100 allows you to place your VGA display and USB peripheral units up to 100 meters from your PC. The product set consists of two units, the Transmitter and Receiver, connected by a single Cat 5 or Cat 6 “link” cable (also called PDS or Ethernet cable) up to 100 metres in length.
Any VGA compatible display can be connected to the Receiver unit and any USB 1.1 compatible peripherals, including keyboard, mouse, scanner, hard disk, and docking cradles, can be connected to the four port hub on the Receiver. The Transmitter unit is connected to the appropriate VGA (HD-15) and USB connectors on the computer.
How it works
The transmitter unit is connected to the VGA and USB outputs on the computer. This unit converts the VGA signal into three balanced analogue signals (Red, Green, and Blue with horizontal and vertical sync signals carried as common mode signals on two of the colors) which are transmitted on three of the four twisted pairs in the Cat 5/6 cable. The fourth pair is used for transmitting the digital data of the USB signals which are packed, multiplexed and converted to balanced signals in
the transmitter.
Transmission is in real time with no discernible delays on either video or USB. The user’s display and USB peripherals are connected to the receiver unit, which converts the blanced signals back into their original VGA and
USB formats.
An optional skew compensation unit can, if necessary, be provided to adjust for color shift due to the unequal twist rates of the cabling. Ask your supplier. |
