1. If the DVI or HDMI device requires the EDID information, please use EDID Reader/Writer to retrieve and
provide DVI/HDMI EDID information.
2. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz LAN cable and
ASTRODESIGN Video Signal Generator VG-859C.
3. The transmission length is largely affected by the type of LAN cables, the type of HDMI sources, and the type
of HDMI display. The testing result shows solid LAN cables (usually in bulk cable 300m/1000ft form) can
transmit a lot longer signals than stranded LAN cables (usually in patch cord form). Shielded STP cables are
better suit than unshielded UTP cables. A solid UTP CAT5e cable shows longer transmission length than
stranded STP CAT6 cable. For long extension users, solid LAN cables are your only choice.
4. EIA/TIA-568-B termination (T568B) for LAN cables is recommended for better performance.
5. To reduce the interference among the unshielded twisted pairs of wires in LAN cable, you can use shielded
LAN cables to improve EMI problems, which is worsen in long transmission.
6. Because the quality of the LAN cables has the major effects in how long transmission distance will be made
and how good is the received display, the actual transmission length is subject to your LAN cables. For
resolution greater than 1080i or 1280x1024, a CAT6 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.
8. The HSMR has been tested extensively and found that it doesn’t require external power supply. If in rare
situation you find it cannot work with the HSW44C, please use any +5V power adapter to plug in the power
jack and see if it can work. If not, please contact your technical support for further service.
9. Additional IR remote controls and IR emitter cables can be purchased as optional accessories to control the
HDMI sources located separately.
