1. All the transmission distances are measured using Belden CAT‐5e 125MHz Solid cable and
ASTRODESIGN Video Signal Generator VG‐859C. The transmission distance is defined as the
distance between the SP‐9018 and the remote VGA display.
2. The transmission length is largely affected by the type of LAN cables, the type of A/V sources, and
the type of A/V display. The testing result shows solid LAN cables (usually in 300m/1000ft form)
can transmit a lot longer signals than stranded LAN cables (patch cord). 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.
3. EIA/TIA‐568‐B termination (T568B) for LAN cables is recommended for better performance.
4. 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.
5. 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 CAT‐6 cable is recommended.
