3) 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.

1) With LanScaper™ powered off, connect LanScaper™ to a jack or plug at the workstation

location for which the Ethernet port is to be located.

2) 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 finding the cable with a tone tracer at the other end (equipment closet).

3) If an Ethernet link is active on the cable the LanScaper™ turns on its link LED and begins

flashing 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.

- If the jack or plug is unknown, run Jack ID test first. 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 specific 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 configuration information must be entered in SETUP first.(PING Setup option)
1) With LanScaper™ powered off, connect to network.
2) 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 configuration. Once PINGing begins, a PING status screen will be
displayed, showing acronyms for each active conversation.

3) Press left or right arrows to move curser ( ) next to a device acronym. Press SEL button to view

more information about a device. There are a total of three screens to view. Press SEL button to
advance to the next screen or the screen will advance automatically after 10 seconds.

- Two LanScaper™ testers can be used to

exercise a cable link with no additional equipment being required. This can also be done through
a HUB or switch with or without any other equipment being present. The two LanScapers™ will
be referred to as the Validator and the PING Generator. The Validator uses the Validate Link
mode and the PING Generator uses PING Test mode.

1) Connect the Validator to one end of the link to be tested.
2) Press NTWRK button until Validate Link is displayed. Press SEL button to activate test.
3) In SETUP, set PING Generator to DHCP Off (see To Change PING Addressing, below). A

specific manual address does not need to be set, the PING Generator will recognize the Validator
and assign addressing.

4) Connect the PING Generator to the other end of the link.
5) On the PING Generator, press NTWRK button until PING Test is displayed and press SEL

button to begin.

6) The target or router acronym will change to Val on the PING Generator when the Validator is

found and addressing assigned. The PING Generator operates and accumulates information as in
the normal PING Test. The Validator displays a packet count only on its screen.

2.6 To PING Devices on a Network

2.7 To Validate a Cable Link by Functional Testing
