Support - FAQ
FAQ of each product lines are grouped together in separate FAQ pages, user ought to identify the product and matching page below.
Q: What do "T" & "R" stand for? How many "R"’s can pair with one "T"? How many "T" can co-exist at the same time?
A: "T" -- transmitter or Tx, "R" -- receiver or "Rx", up to 4 "R" can pair with one "T". As long as they all use the same communication channel, no performance degradation will occur". Maximum 10 sets of "T"+"R"'s are possible at the same time.
Q: What's the difference between HD120 and HD120E? Can I swap out HD120-Tx's and HD120-Rx(E)'s antennas?
A: HD120E includes HD120-Rx(E) receiver with five external antennas.
Q: Are HD120-Tx and HD120-Rx/HD120-Rx(E) FCC/CE certified?
A: Yes, they are.
Q: Will the SUV HD120/HD120E work with 5.x GHz Wifi and other devices? And do I need to apply for licenses to operate?
A: Yes and No.
Q: What is modulation scheme used and bandwidth required?
A: The system is MIMO and COFDM/16-QAM in 40 MHz bandwidth
Q: What does Line-of-Sight distance mean?
A: A straight line along with "T" and "R". Up to 260 meters( 860 feet ) for HD120 and up to 400 meters(1280 feet) for HD120E outdoor tested by the manufacturer. Actual distance varies with surrounding interferences, blocking objects
( landscape, size of metal object, wall and human bodies ) and environment humidity, which attenuate signal strength in addition to path loss.
Q: Can I use a notebook's HDMI port as the source to "T"?
A: Yes. The "T"'s HDMI input covers a wider range of resolution compared to SDI, which covers SDI, HD-SDI and FullHD only. So you might see non-standard signal on HDMI monitor only. Note: Use DVI-HDMI and HDMI-DVI adapters between HDMI and DVI.
Q: What is the maximum cable length to use in "T" and "R"? A: 100-meter(300 feet) for SDI, 15-meter(45 feet) for HDMI; however, Active Optical Fiber HDMI or SDI cable can run the signal in a greater length.
Q: Will audio be transmitted together with video without latency?
A: Yes. Both video and the first two embedded audio are transmitted, no latency, both video and audio are AES 128-bit encrypted.
Q: After running the "T" a while, the "T" surface is hot - is this normal?
A: Yes it is normal. The unit's heat is dissipated via the metal enclosure.
Q: Where to contact techsupport?
A: User can always contact Shining’s techsupport at (714)3128998 or or write to firstname.lastname@example.org, and access http://www.shining.com, SUV page for additional information.
Q: No video showing on the monitor attached with the "R".
A: They are many possible causes:
1). Check both T's and R's power lights status make sure either the clicked in battery, or extended battery, or attached wall-mount adapter is in working condition.
2). Make sure both "T"'s and "R"'s power are ON.
3). Check both communication setting, they should be identical. Must re-cycle the power of the T or R if changed.
4). If the "T" is attached with a computer's HDMI output, and it's resolution is not HD( 1920x1080 pixels ) format, the HD-SDI output attached with the "R" would be turned off, but HDMI would still be on.
Q: "Link connecting" message showing on "R".
A: "R" is up running but not "T", refer to "Transmitter Installation".
Q: Video quality on the "R"'s monitor is noisy.
A: Make sure the HDMI cable is 100% double shielded. Make sure the SDI cable is 75-ohm also 100% shield. Bring in the "T" and "R" closer, and make sure RSSI is good.
Change different communication channel for both "T" and "R". Must re-boot both "T" & "R" to take in the new selection.
