2.4 To Measure Length of a Cable

Connect cable to main unit. A remote may be at the other end, but is

not required.

Turn on unit by pressing CABLE button. Press CABLE button until

Cable Length is displayed, then press SEL button. To change length

units between feet and meters, use setup mode.

Press up/down arrows to adjust length constant. If length constant

is unknown for a particular cable, a known length of cable may be

used to set the constant. Fifty feet or more is suggested to minimize

the resolution error (1 foot in 50 is 2% uncertainty). Connect known

cable to tester and change the cable constant using up/down arrows

until the length reads correctly.

2.5 To Locate an Ethernet Port

With LanScaper™ powered off, connect LanScaper™ to a jack or

plug at the workstation location for which the Ethernet port is to be

located.

Press NTWRK button, LanScaper™ will power up in the Flash

Link LED mode and connect to the Ethernet port on a HUB, switch

or NIC. Even if no connection is made, tone is generated on the

cable to aid in nding the cable with a tone tracer at the other end

(equipment closet).

If an Ethernet link is active on the cable the LanScaper™ turns on

its link LED and begins ashing it in unison with the link indicator

on a port of the HUB, switch or NIC at the other end. Tone is also

generated on the cable in this condition, but at a different cadence to

indicate having established a link.

2.6 To PING Devices on a Network

If the jack or plug is unknown, run Jack ID test rst. The PING function

operates in two modes DHCP On and Off (Manual). This is selected

in SETUP by the DHCP On/Off option. No other entries are required to

establish communications with a router and a DNS server on a DHCP

network. To PING a specic target (Tg1-4), the address must be entered

and the desired target address selected in SETUP before starting the

PING test. In DHCP Off mode, all IP conguration information must be

entered in SETUP rst.(PING Setup option)

With LanScaper™ powered off, connect to network.

Press NTWRK button repeatedly until PING Test is displayed on

screen (two presses when off). Press SEL button to enter test.

Several status screens will be displayed while establishing a link and

negotiating the DHCP conguration. Once PINGing begins, a PING

status screen will be displayed, showing acronyms for each active

conversation.
