The NETmapper is a unique and versatile tool for professional network administrators to quickly verifying network connectivity and get essential information from the entire network for troubleshooting. It in corporate both an on–line active network tester and an off–line cable checker. It can also check for polarity and voltage of telephone lines. The NETmapper also has an analog tone generator and port–finder function for network cable and port identification.

• Incorporates TDR technology

• On–line test: Displays the Ethernet port status, ping default router, ping DNS server and ping user defined device...etc.

• Off–line test: Wire map/twisted mapping/cable length/tone generator and port–finder

• Reporting voltage and polarity if voltage is present on pin 4/5 (telephone line)

• Wire map for cables opened, shorted, reversed, crossed, split pairs, mis–wire, ad shield continuity

• Wire map results are displayed by pin–to–pin format

• Displays the wire map and cable faults with remote ID in one screen

• Measures twisted pairs, map, and length of Cat5, Cat5E, Cat6 and Cat7 cables without remotes

• Self–calibrating function allows for increased measuring accuracy when testing length of non–standard cables

• Displays measurements in both meters and ft.

• Port-finder function to locate corresponding socket on 10/100M or Giga hub/switch

• Tone generator sends 1kHz tone on all pins with 4 tonalities

• RJ-45 port protection from damage due to high voltage from telephone line

• Low battery indicator
