Chapter 3: Initial Installation
3. Initial Installation
1. Using quality HDMI cables, connect a CATx transmitter (VX-1001-TX,
VX-1002-TX) or presentation switcher (AVSC-0401H) to the CATx IN port
of the scaling receiver.
NOTE: Make sure that the source and display are 4K compatible if you are
attempting to transmit an Ultra HD signal—check that all devices are
correctly configured for input/output compatibility.
2. Connect a good quality, well-terminated CAT5e or higher cable between the
CATx OUT of the transmitter or switcher to the CATx IN of the VX-1003-RX
Scaling Receiver.
NOTE: The maximum transmission distances for the extenders are 230 feet
(70 meters) with CAT5e/CAT6 or 328 feet (100 meters) with
CAT6a/CAT7. This value applies to perfect transmission conditions—
including straight cable runs with no electrical interference, bends, kinks,
patch panels, or wall outlets.
If any of the above is a factor in your installation, transmission range may be
affected—avoid this where possible.
3. Connect the HDMI display device (LED/LCD display or projector) to the HDMI
OUT of the VX-1003-RX Scaling Receiver.
4. Connect the audio system to the S/PDIF OUT or Audio OUT port of the
VX-1003-R X.
NOTE: We strongly recommend using the supplied mounting brackets to secure
the receiver to a flat surface behind/near the display device.
Sudden movement of these devices could lead to loss of picture/sound
if connections loosen or strain, resulting in unnecessary service call-backs.
4. Connect the included 12-VDC power supply to the VX-1001-TX Transmitter or
AVSC-0401H Presenatation Switcher and power it on. The PoH function car-
ries power along the length of the cable one way to power the Receiver. No
additional power supply is required at the display end of the cable run.
Power, Status, and HDCP, and Link LEDs illuminated on transmitter/switcher and
scaling receiver units indicates a successful connection. An HDCP light illustrates
the presence of encryption within the signal. The Power and Link LEDs are static
lights. The Status LED should be blinking.
