Gefen EXT-HDMI-CAT5-844 - Manual (Page 5)

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 8X4 CAT-5 MATRIX FOR HDMI
• To use the extender functionality of the 8x4 CAT-5 Matrix for HDMI the
supplied 1 foot HDMI jumper cables must be used to connect the HDMI
output ports to the HDMI extension input ports. Please see page 8 for
details.
• Use two industry standard CAT-5, CAT-5e or CAT-6 cables to operate each
of the HDMI Over CAT5 Receivers. Gefen recommends shielded CAT-6
cabling for maximum performance.
• For 1080i video, maximum extension is 300 feet (91 meters).
• For 1080p video, maximum extension is 150 feet (45 meters).
• IR repeater functionality is only from the receiving unit to the sending unit. IR
data cannot be transmitted from the sending unit to the receiving unit.
• When a display connects to a source being viewed by other displays, a short
fl ash may appear momentarily on the displays already viewing that source.
This is normal operation as new handshakes for HDCP are being made.
• Local displays that are not using the extension functionality of the 8x4 CAT-5
Matrix for HDMI can only switch their viewing source via the RS-232 Serial
Control Interface or the optional RMT-16IR remote control.
• Important Note: The 8x4 CAT-5 Matrix for HDMI incorporates a 2x1
switch in front of each input on a traditional 4x4 matrix. This allows for the
connection of up to 8 different HDMI source devices with a maximum of 4
sources available for viewable at any one time. Each of the 4 switched inputs
on the 8x4 CAT-5 Matrix for HDMI are labeled as “A” and “B”. Both “A” and
“B” for each input cannot be active at the same time.
Example A (Multiple outputs viewing the same input source)
Devices: 1A (DVD player) & 1B (Cable STB)
Scenario: Outputs 1 and 2 are both viewing input 1A (DVD).
Action: User viewing output 1 switches the input from 1A (DVD) to 1B
(STB).
Result: Both outputs 1 and 2 will be switched to viewing 1B (STB).
Example B (Multiple outputs viewing separate input sources)
Devices: 1A (DVD player), 1B (Cable STB), and 2A (Video Game system)
Scenario: Output 1 is viewing 1A and output 2 is viewing 2A.
Action: User viewing output 1 switches the input from 1A (DVD) to 1B
(STB).
Result: Output 2 is not affected by the change of 1A to 1B because it is
viewing a source (2A) on a different input.
• Display information (EDID) from the displays attached to the 8x4 CAT-5
Matrix for HDMI need to be sent back to the input sources. Please see page
11 for EDID management features and options.
