User manual LUMAGEN HDMI-CAT6

[. . . ] - Programmable cable equalization at both transmitter and receiver allows system specific settings with lower cable jitter than dynamic-cable-equalization solutions. - Power supplies at both transmitter and receiver eliminate powersupply-current induced cable voltage-drop. - Using CAT6 STP, with 24 AWG HDMI, cables supports 1080p60 for a total distance of over 40 meters, with up to 30 meters of CAT6 STP cable, under nominal conditions. [. . . ] By having DDC buffers in both the transmitter and receiver, losses for each of the three cables can be isolated and corrected. There is a separate power supply for the transmitter and the receiver. This eliminates voltage-drop caused by powering the repeater chip through the CAT cable. Lumagen has measured significant voltage drop in other products that power their repeater chip through the CAT cable, which reduces their signal integrity. Separate power supplies eliminate this issue. Installation Instructions: Lumagen specifies the use of shielded CAT5e STP or CAT6 STP cable to meet EMI regulations. Non-shielded (UTP) cable will function, but will not meet EMI regulations. An advantage of STP cable is that it is less susceptible to crosstalk from other cables in a cable-bundle environment. CAT6 STP cable supports longer reliable cable lengths compared to CAT5e STP cable because its electrical characteristics are better suited for video applications.

Lumagen recommends connecting cables in the following order: - Connect the control CAT cable and then the video CAT cable to the HDMI-CAT6 receiver. - Connect the HDMI cable from the HDMI-CAT6 receiver to the projector/display. - Connect the provided 5-VDC power-supply to the HDMI-CAT6 receiver and then plug it into an outlet. - Connect the CAT cable for control and then the CAT cable for video to their respective output on the HDMI-CAT6 transmitter. - Connect the HDMI cable from the source to the HDMI-CAT6 transmitter. - Connect the provided 5-VDC power-supply to the HDMI-CAT6 transmitter and then plug it into an outlet. - Turn the system on. Status Indicator Lights: There are two light-emitting-diode (LED) indicator lights on the transmitter and on the receiver. These show the connection status as described below: - ACTIVE: On if the external 5-VDC power is supplied, and HDMI "Standby Power" is active. - VIDEO: On if the ACTIVE light is on, and the video input signals are actively driven. [. . . ] This allows the ground wires of the audio/video cables to handle any ground loop current rather than the audio and video signals themselves. © 2010 Lumagen, Inc. page 3 of 5 Rev 1. 0 © 2010 Lumagen, Inc. page 4 of 5 Rev 1. 0 Setup Tips and Trouble Shooting: - When installing new CAT cable, always install CAT6 STP cables (i. e. - Avoid bundling the high-frequency video cables with LAN and other digital cables. Using CAT6 STP cables reduces the potential for crosstalk between cables, but it is still a good idea to run the video cables separately. [. . . ]
