Select the 1st pair of multi-channel audio
Select the 2nd pair of multi-channel audio
Select the 3rd pair of multi-channel audio
Select the 4th pair of multi-channel audio
Only 1 pair can be selected to audio output and only HDMI output 1 supports such a
function. Keep only one pin of DIP switch ON position at all times.
For firmware update, there are 2 paths for updating new firmware, and each path is
responsible for different components. USB port is designed for HDMI related chipset
control and RS-232 port is mainly for the IR, RS232 and control flow.

CHANNEL CONTROL
Method A: Push Buttons
Push the HDMI input switch buttons on the front panel, the source will be sequentially changed.
Method B: IR Remote Control
Please push the desired input channel for each output port. The setting will take effect within a
couple of seconds.

NOTICE
1. If the DVI or HDMI device requires the EDID information, please use CV-1001 or CV-5005H EDID
Reader/Writer to retrieve and provide DVI or HDMI display EDID information.
2. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz
UTP cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
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.
5. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, one
can use double shielded STP cables to improve EMI problems, which is worsen in long
transmission.
6. 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

11
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.
