Discovering฀Cabling฀Characteristics฀
Discover฀mode฀lets฀you฀quickly฀check฀wiremaps,฀measure฀
length,฀and฀determine฀if฀the฀cabling฀is฀connected฀to฀a฀
network฀or฀video฀device.฀Discover฀mode฀runs฀continuously฀
to฀help฀you฀isolate฀intermittent฀connections.฀
Discover฀mode฀tells฀you฀about฀the฀following:฀
For฀twisted฀pair฀cabling฀
• Wiremap฀
• Length฀
• Speed฀of฀an฀attached฀port฀(such฀as฀a฀hub฀or฀a฀
network฀interface฀card฀in฀a฀PC)฀
• Connection฀to฀telephone฀service฀
For฀75฀Ω฀coaxial฀cabling฀
• Continuity฀
• Length฀
• Indicates฀signal฀presence฀or฀connection฀to฀a฀device฀
(such฀as฀CATV฀service,฀VCR,฀DVD฀player,฀satellite฀dish,฀
or฀antenna)฀
• TDR฀(time฀domain฀reflectometry)฀plot.฀This฀shows฀
impedance฀changes฀along฀the฀cabling.฀
