1:4 HDMI TP Trans & DA

The VM−1H4C is a high−quality twisted pair distribution amplifier for HDMI signals. The unit receives serial commands and IR signals transparently via the RS−232 port and the TP link. It reclocks and equalizes the input signal and distributes it to four DGKat TP outputs.

VM−1H4C features include:

  • Max. Data Rate - 4.95Gbps (1.65Gbps per graphic channel).

  • HDTV Compatible.

  • HDCP Compliant.

  • DGKat™ Signal Integration - Kramer’s unique technology for converting TMDS as well as control and communication to signals that run over twisted pair cables. We strongly recommend using Kramer DGKat™ cables designed specifically for optimum performance.

  • I-EDIDPro™ Kramer Intelligent EDID Processing™ - Intelligent EDID handling & processing algorithm ensures Plug and Play operation for HDMI systems.

  • HDMI Support - x.v.Color™ and uncompressed audio channels, Dolby TrueHD, DTS−HD.

  • 3D Pass-Through.

  • Kramer Equalization & re-Klocking™ Technology - Rebuilds the digital signal to travel longer distances.

  • System Range - Up to 90m (295ft) at 1080i, or up to 30m (98ft) at 1080p on shielded BC−DGKat524 cable. Up to 90m (295ft) at 1080i, or up to 70m (230ft) at 1080p on shielded BC−DGKat623 cable. Up to 100m (330ft) at 1080i or up to 90m (295ft) at 1080p on shielded BC−DGKat7a23 cable.

  • Power Connect - The VM−1H4C provides power to the twisted pair receivers when they are within 270ft (90m) of the transmitter.

  • Cable - Requires STP (shielded twisted pair) cable. For optimum range and performance, use Kramer's BC−DGKat524, BC−DGKat623 or BC−DGKat7a23 cables. Note that the transmission range depends on the signal resolution, source device and display used. The distance using non−Kramer CAT 5, CAT 6, and CAT 7 cables may not reach these ranges. Use only shielded cable where both ends of the shield are soldered to ground.

  • Active Input & Output LED Indicators.

  • Serial Command Handling - Receives serial commands transparently via the RS−232 port and the TP link.

  • Desktop Size - Compact size. 2 units can be rack mounted side−by−side in a 1U rack space with an optional adapter.
