1.
USB or RS-232 control must be connected either one at a time. Connecting both types of cables
may cause command confusion.
2.
When adjusting the signal level on the receiver unit, please dial the rotary control switch from 7
to 0 and stop turning the rotary switch whenever the audio/video is playing normally.
Inappropriate signal level setting may cause overpowering issues that would shorten the
product’s life significantly!
3.
Do not press any button more than once within 1 second on the
INPUT SELECT
of receiver
units and the IR remote control as both devices need about 1 second to communicate with the
router unit and validate the command you sent. Press multiple times within 1 second segment
could lead to unexpected lock-on failure.
4.
All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e
125MHz UTP cable and ASTRODESIGN Video Signal Generator VG-859C.
5.
The transmission length is largely affected by the type of Category 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 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.
6.
EIA/TIA-568-B termination (T568B) for category cables is recommended.
7.
To reduce the interference among the unshielded twisted pairs of wires in category cable, use
double shielded STP cables to improve EMI problems, which is worse in long transmission.
8.
Because the quality of the category 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.
9.
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.
10.
The PRO-8X8-HDMI-CAT has been tested extensively and found that the receiver units don’t
require external power supply. If in rare situation you find it cannot work with the router unit,
please use any +5VDC power supply unit to plug in the power jack and see if it can work. If
not, please contact our technical support for further service
11.
Additional IR remote controls and IR blaster cables can be purchased as optional accessories to
control the HDMI sources located separately.
