RECEIVER UNIT DESCRIPTIONS 1 EQ The EQ adjustment or Trim Pot is used to equalize the signal to compensate for the extension distance and the quality/skew variances that are found in different CAT-6a cabling brands. 2 Power The LED power indicator will become active once the included 5V DC power supply is properly connected beten the unit and an open wall power socket. 3 Link 2.1 This port is used to receive the signal from DVI In 2 on the Sender unit using CAT-6a cable.
CONNECTING THE 2X DUAL LINK DVI EXTENDER OVER CAT-6 How to Connect the 2x Dual Link DVI Extender over CAT-6 1. Connect the included dual-link DVI cables between the DVI outputs on each computer and the DVI input connectors on the 2x Dual Link DVI Extender over CAT-6 Sender unit. 2. Connect four CAT-6a cables between the Sender and Receiver units. Note that each connector on the Sender and Receiver unit is identified by Link 1.1, Link 1.2, Link 2.1, and Link 2.2.
DIP SWITCH CONFIGURATION DIP Switch Location On the bottom of both the Sender unit and Receiver unit is a bank four (4) DIP switches. The DIP switches on the Sender unit allow the management of EDID, fiber optic extenders, and HDCP. The DIP switches on the Receiver unit do not provide any function and reserved for future expansion. Sender unit The four DIP switches on the Sender unit DIP Switch 1 - EDID Management • ON - Pass Through EDID DDC and HPD are passed through.
DIP SWITCH CONFIGURATION DIP Switch 2: +5V for Fiber Optic Extenders • ON - Enable +5V Enable +5V for DVI fiber optic extenders. • OFF (default) - Disable +5V Disable +5V for DVI fiber optic extenders. DIP Switch 3: DVI Support* DIP switch 3 is only functional when DIP switch 1 is set to OFF (Local EDID). • ON - DVI Mode If a DVI connection is used, set DIP 3 to the ON position. DVI is supported by disabling HDCP pass-through.
ADJUSTING THE SIGNAL QUALITY Adjusting the Signal Quality The 2x Dual Link DVI Extender over CAT-6 Receiver unit has two trim pot (trim potentiometers) to compensate for the extension distance and the quality/skew variances that are found in different CAT-6a cabling brands. EQ1 adjusts the output signal for DVI 1 and EQ2 adjusts the output signal for DVI 2. If there is no output video or if output video contains video artifacts and/or video noise such as snow, use the steps below to adjust the trim pot. 1.
