HARDWARE INSTALLATION
1. Connect a HDMI or DVI source (such as a Blu-ray Disc player) to the transmitting unit
EX-57VAC-100E-A-TX.
2. Connect a HDMI or DVI display (such as a LCD TV) to the receiving unit EX-57VAC-100E-A-RX.
3. Connect IR Blaster/Receiver to both TX and RX units.
4. Connect a Cat-5/5e/6 cable between the transmitting and receiving units.
5. Make sure this Cat-5/5e/6 cable is tightly connected.
6. Plug in 24V DC power supply unit to the power jack of the receiving unit EX-57VAC-100E-A-RX or the
transmitting unit EX-57VAC-100E-A-TX.

NOTICE
1. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz UTP
cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
2. Incorrect placement of IR Blaster and Receiver may result in the failure of the IR extenders. Please
check carefully before plugging in the IR extender to the respective IR sockets. Warranty will not cover
the damage.
3. The transmission length is largely affected by the type of Cat-5/5e/6 cables, the type of HDMI sources,
and the type of HDMI display. The testing result shows solid UTP cables (usually in the form of 300m
[1,000ft] bulk cables) can transmit a lot longer signals than stranded UTP cables (usually in the form of
fixed length patch cords). Shielded STP cables are better suited than unshielded UTP cables. A solid
UTP Cat-5e cable shows longer transmission range than stranded STP Cat-6 cable. For long
extension applications, solid UTP/STP cables are the only viable choice.
4. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended for better performance.
5. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, one can
use shielded STP cables to improve EMI problems, which is worsen in long transmission.
6. Because the quality of the CAT5/6 cables has the major effect on how long the transmission limit can
achieve and ho
w good is the received picture quality, the actual transmission range is subject to one’s
choice of Cat-5/5e/6 cables. For desired resolutions greater than 1080i or 1280x1024, a Cat-6 cable is
recommended.
7. If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input [HDMI input #1]
generally can produce better transmission performance among all HDMI inputs.
