Installation
Connecting the DisplayPort Extender over CAT-7
1. Use the included DisplayPort cable to connect the DisplayPort source to the DP In
port on the Sender unit.
2. Connect a DisplayPort cable from the DP Out port on the Receiver to the display.
3. Connect two CAT-7 cables between the Sender and Receiver units. Each connector
on the Sender and Receiver unit is identied as Link 1 and Link 2. When connecting
the CAT-7 cables, make sure that each CAT-7 cable that is connected to the Sender
unit is connected to the corresponding jack on Receiver unit (e.g. Link 1 --> Link 1,
Link 2 --> Link 2).
4. Connect the included 5V DC locking power supply to the Sender unit. Do not overtighten the locking connectors. Plug the AC power cord from the power supply
to an available electrical outlet.
Sample Wiring Diagram
NOTE: The DisplayPort Extender over CAT-7 will support resolutions
up to 1920 x 1200 (WUXGA) and 1080p Full HD if only a single
CAT-7 cable is used. Two CAT-7 cables must be used to support
resolutions up to 2560 x 1600.
If only a single CAT-7 cable will be used, the CAT-7 cable must
be connected between the Link 1 connectors on both the Sender
and Receiver unit. This same CAT-7 cable is used to power the
Receiver unit.

Operating the DisplayPort Extender over CAT-7
Hot-Plug Detect (HPD)
The DisplayPort Extender over CAT-7 has an HPD button on the front of the Receiver
unit. Pressing this button will cycle the HPD (Hot-Plug Detect) line on the display (sink)
device. This HPD button provides the same effect as disconnecting then reconnecting the
DisplayPort cable from the Receiver unit. Cycling the HPD line will cause the Receiver unit
to re-read the EDID of the display and send it back to the DisplayPort source.

Adjusting the Signal Quality
The DisplayPort Extender over CAT-7 has an equalization device on the front of the
Receiver unit. This 16-position rotary switch is used to adjust the boost level depending
upon the length of the CAT-7 cable.
1. Insert a small at-headed tool into the notch on the rotary switch.
The table below provides examples of various cable types and lengths for CAT-6
cabling.

Appendix
Surface-Mounting Instructions
The Gefen DisplayPort Extender over CAT-7 can be mounted on any horizontal or vertical
at surface (e.g. wall or inside / outside a cabinet with wood / drywall screws) as shown in
the diagram above. There should be an inch or two of clearance between the edges of the
unit and any walls or vertical surfaces to allow for enough clearance for connection and
disconnection of the DisplayPort cable.
For installation on a drywall surface, use a #6 drywall screw. When installing, it is
recommended to use the center hole on a stud.
