DIP Switch Conguration
Basic Operation
Basic Operation
On the bottom panel of the Sender unit is a bank of 4 DIP switches. Remove the piece of
colored tape to reveal the DIP switch bank. These DIP switches provide control over EDID
management and color depth. DIP switches 3 and 4 are not used.
Default Settings
The following table lists the default (factory) settings of each DIP switch. See the following
page for details on each DIP switch function.
DIP Switch Description
1 ON
• Uses pass-through (downstream)
EDID mode
2 OFF
• Deep color is disabled.

EDID Management
The DVI over 1 CAT6 w/ Galvanic Isolator can be switched between two EDID modes:
Internal or Pass-through. After changing DIP switch 1, the Sender unit must be
power-cycled for changes to take effect.
DIP Switch 1 Description
ON
(default)
Pass-through mode. DDC and HPD are
passed through. Both the connection status
and the full video capabilities of the monitor
are passed to the source device.
OFF Internal EDID mode. In this mode, a
generic EDID will be sent to the source
device. This setting is useful when
sufcient EDID data is unavailable from the
display device or EDID-related problems
are encountered.
Color Management
This feature is used to control the color depth for resolutions up to 1080i. By default, the
color depth is set to 8-bit. If the output resolution is 1080p or if DIP switch 1 is ON, then
this DIP switch setting has no effect.
DIP Switch 2 Description
OFF
(default)
Disables Deep Color support on the output
(display) device.
ON Enables Deep Color (12-bit) support on the
output (display) device.

The Receiver unit of the DVI over 1 CAT6 w/ Galvanic Isolator has a trim pot that is used to
equalize the output signal, compensating for extension distance and cable skew. 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. Use a small at-headed tool to turn the EQ pot.
2. The trim pot has eight different positions (0 through 7). Turn the trim pot in a clockwise
direction until it clicks to the next position. The arrow indicator on the trim pot will
indicate the current position.
3. Check the image.
4. If necessary, continue adjusting the rotary switch until the issue is resolved.

The Sender and Receiver units can be mounted on any at surface, as shown below
(screws not included). 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 DVI cables.
For installation on a drywall surface, use a #6 drywall screw. When installing, it is
recommended to use the center hole on a stud.
