The B140-004 transmits a DVI-D Single-Link signal to four monitors up to 200 ft. away using a single Cat5e/6 patch cable. To achieve maximum distance and resolution, use 24AWG Solid Wire Cat5e/6 cable (Tripp Lite's N202-Series). An additional DVI port is provided for the connection of a local monitor. This local DVI port can also be used to daisychain up to 3 units together, allowing for the connection of up to 13 monitors (12 remote, 1 local). Mounting hardware is included that allows the unit to be rackmounted, wallmounted or pole mounted. In addition, up to three units can be mounted in 1U of rack space using a Tripp Lite B132-004-RB 19" rackmount bracket. The B140-002 is compatible with all operating systems, and is plug and play, with no software or drivers required. Compliant with the Federal Trade Agreements Act (TAA) for GSA Schedule purchases.
