NOTICE:
1. When adjusting the signal level on the receiver module, please dial the rotary control switch from MIN to MAX
and stop turning the rotary switch whenever the audio/video is playing normally. Inappropriate signal level
setting may cause overpowering issue that would shorten the product life significantly!
2. If the DVI or HDMI TM device requires the EDID information, please use EDID Reader/Writer to retrieve and
provide DVI or HDMI TM display EDID information.
3. All HDMI TM over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz UTP
cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
4. The transmission length is largely affected by the type of Cat-5/5e/6 cables, the type of HDMI TM sources, and
the type of HDMI TM 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.
5. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended for better performance.
6. 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.
7. Because the quality of the CAT5/6 cables has the major effect on how long the transmission limit can achieve
and how 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.
8. If your HDMI TM display has multiple HDMI TM inputs, it is found that the first HDMI TM input [HDMI TM input #1]
generally can produce better transmission performance among all HDMI TM inputs.
Possible Issues and Solutions:
1. No Audio/video Signal on the Display or Signal is going in and Out:
a. Please test your RJ45 cables with a Fluke or similar tester to make sure that all the wires are connected
and the distance is within the limits.
b. If you are using patch panel or and RJ45 wall plates, the distance will be reduced, please do a direct con-
necting bypassing all additional equipment.
c. Please try to re-terminate your CAT5/6/7 wire to 568B
d. Please try adjusting EQ gain on the receiver unit
e. Please try changing a mode on the transmitter to #0 or to #1 (depending on the audio format required
f. Please go into the menu of the source device and select 720p/1080i or 1080p resolution instead of AUTO
g. If the sync device is a projector or AVR, please try learning EDID, instructions are on the previous page
2. When connected between 3D player and 3D display, only able to see 2D image:
a. Please try changing “MODE” on the transmitter module to 4 or 6
b. Please go into the menu of the source device and enable 3D
3. Signal is Going In and Out when going into the AVR; however works well connected directly to the TV
a. Please try Learning EDID of the AVR while the AVR HDMI TM out is connected to the display (both AVR and
Display should be ON)
b. Select “MODE” on the transmitter to # 0, #2 or # 4
