  • Page 7: Overview

    Overview The VM-114H2C 2 Input 1:4 HDMI DA/2x CAT5 Outputs is a switcher/distribution amplifier for HDMI and TP (twisted pair) signals. It reclocks and equalizes one of two selectable input signals and distributes it to two HDMI and two TP outputs.

  • Page 8: Using Twisted Pair Cable

    Using Twisted Pair Cable Kramer engineers have developed special twisted pair cables to best match our digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23 (CAT 7a 23 AWG cable). These specially built cables significantly outperform regular CAT 5 / CAT 6 / CAT 7a cables.

    5.3.2 Local IR Control and IR Pass-Through Using the VM-114H2C The VM-114H2C provides an IR sensor and a 3.5mm mini jack for connecting a remote IR emitter or sensor. When the VM-114H2C is connected to suitable transmitters and receivers (for example, the TP-573 and TP-574), the VM-114H2C can act as a pass-through for IR control signals, allowing remote control of multiple devices using multiple IR remote controllers.
