Cable Electronics HSW88C User Manual

SAFETEY NOTICE

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 reduce EMI problems,

    which is worsen in long transmission.
6. Because the quality of the LAN cables has major effects in transmission 
    distance, always use high quality cables. For resolution greater than 1080i 
    or 1280x1024, a CAT6 solid wire 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 HSW88C, please use a +5V power adapter to plug in the 

    power jack and try again. If not, please contact your technical 

    support for further service.
9. Additional IR remote controls and IR blaster cables can be purchased 

    as optional accessories to control the HDMI sources located separately.
