The StarTech ST1218T eight-port extender is designed to distribute a VGA source signal to remote displays up to 492 feet (150 meters) away over standard Cat 5 (or better) cabling. It's great for expanding the range of your advertisements in auditoriums, trade-shows, and retail environments, or positioning your display in a convenient viewing area while keeping the host system in a clean and secure environment.

This unit is a transmitter unit only, and requires one Receiver Unit (ST121R) per display that you are connecting. You can use the VGA over Cat 5 Repeater (ST121EXT) for an additional 492-feet (150 meters) extension. Up to three repeater units can be used between the transmitter and the receiver. This unit is also daisy-chainable for more ports and a greater range. The pure hardware design provides an easy installation and setup; no software or drivers are required.

  • newegg Two Local VGA Connections In addition to eight RJ45 ports for distribution, this unit features two VGA ports for local display.
  • newegg Daisy-chainable Design This unit can be cascaded to multiply the distribution ports and extension range.
