1.0 INTRODUCTION 1.1 Cautions Warning! Do not attach to primary power lines. The LanScaper™ may be damaged and cause a safety hazard. When connecting to an unknown jack or plug, the LanScaper™ should be off. Once connected, press CABLE button to ID the connection. Caution! Improperly crimped, damaged or un-crimped plugs can damage the jack on the LanScaper™. Inspect plugs for proper termination and crimping before inserting into the tester.
• Auto-MDI/MDI-X like protocol makes connection to HUB, switch or NIC with any patch cable • Two line by 16 character full alphanumeric backlit LCD with icons for clear test results • Auto-off in any mode and low power consumption for long battery life 1.3 Kit Contents NT700 - Basic kit comes with LanScaper™ main unit in a Cordura™ case, (1)- cable test remote, (2)- 1 foot patch cables, (2)- RJ45 to alligator clip cables, (2)- “no fault” RJ12 cables and documentation.
2.0 STEP BY STEP USE INSTRUCTIONS To turn the LanScaper™ off after any test, press and hold PWR button until the display turns off. The tester will turn off automatically after about 15 minutes in all modes except Tone Generator, which is 60 minutes, and Flash Link LED, which is 30 minutes. When connecting to unknown jacks or cables, it is best to begin with the power off and turn the LanScaper™ on after the connection is made. This insures that the voltage check will be run first before any other testing.
2.4 To Measure Length of a Cable 1) Connect cable to main unit. A remote may be at the other end, but is not required. 2) 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. 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.
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. 2.7 To Validate a Cable Link by Functional Testing Two LanScaper™ testers can be used to exercise a cable link with no additional equipment being required.
3.0 FUNCTIONAL DESCRIPTION The LanScaper™ is a jack identifier, cable tester and PING tester in one tester. The LanScaper™ has a backlit LCD display and eight momentary buttons. The rubber end cap at the bottom is the battery compartment cover. The LanScaper™ is powered on by pressing any one of three buttons: PWR, CABLE or NTWRK. The tester will turn on in the last mode used before turning off if the PWR button is pressed.
seen by the LanScaper™ as voltage between the 1-2 and 3-6 pin pairs. The voltage found is reported as “Enet Pwr Source Found = xV” for several seconds, then the test proceeds automatically. 3.2 Cable Test Modes In most modes, the LanScaper™ is constantly testing and reporting results. While it is recommended that an unknown jack connection is always verified by connecting to the tester while it is powered off, it is fine to attach a known network or dead cable or jack to the tester while it is running.
as the top line for a normal data cable. If there is a miswire, the numbers on the second line will indicate the pin numbers detected. If no connection was detected for some of the pins, the second line will be blank in those pin locations. If a short is detected, the second line will have a flashing ‘x’ in that position and the specific short condition displayed on the third line.
across the pair. The SEL button selects one of the four tone sounds provided. The up/down arrows scroll through the pairs and pins that have signal on them. All pins not being driven are held at tester ground. The LanScaper™ will automatically turn off in 60 minutes. 3.3 Network Test Modes 3.3.
DHCP On Mode - After detecting incoming link pulses, the tester requests IP address parameters using the DHCP protocol. The tester displays the message “DHCP Request” and a count of attempts. This protocol requires a response from a DHCP server accessible on the LAN. If no response to its request is received after 10 seconds, the tester will repeat its request, and increment the count on the screen. Once the tester gets a response from a server, it displays the message “Successful”.
the same information can be found using the “ifconfig” and “route” commands. The Netmask and Router information can be entered just as displayed on the PC. The value entered for MyIP must be similar, but not identical to the PC’s IP address. The Netmask defines the addresses that must be common between the PC and the tester for it to be possible for them to communicate directly on the same LAN segment.
No response to the ARP can mean that the IP address assigned to the Router is not correct, the Router is non-functional, or that it is not accessible on the LAN due to some other problem. If the Rtr conversation is selected, and the SEL button pressed, the status displayed is “No ARP response”. Once the Router MAC address is found, the LanScaper™ begins sending ICMP echo request (PING) packets to the Router.
The DNS conversation is only active when PING test is run in the DHCP On mode because the DNS IP address is only available from the DHCP server. (Note that if known, the DNS server IP address can be entered as a Target and PINGed like any other Target.) The DNS server can be local or remote, like a Target. The DNS conversation status is similar to a Target conversation status.
The Validate Link test can also be used on an Ethernet installation with other active devices. Since the Validator verifies that the IP address it will assume is not responding on the network, it will not interfere with other devices on the LAN. The PING Generator must be setup in DHCP Off mode, and its manual IP configuration must be setup to address IP addresses not in use on that LAN. For example, the active Target address could be on the same LAN segment as MyIP.
4.0 SETUP MODE The Setup Mode is provided to set user selectable options and present information that is useful to the user. Entering SETUP is done by pressing the center of the CABLE/NTWRK buttons, which actually activates both buttons simultaneously. The estimated battery life remaining is displayed briefly whenever SETUP mode is entered. The main select menu is scrolled through using the up/down arrow buttons.
4.2 PING Setup Sub-Menu This is the sub-menu title screen for the IP address configuration of the DHCP Off (Manual) PING test mode. The settings of these values interact with each other to force the Router IP address to be accessible on the same LAN segment as the LanScaper™. An off-LAN router cannot be addressed by the tester, and therefore is not a useful setup option. Pressing the SEL button drops the tester into the manual IP configuration screens.
selected, but the LAN did not provide a DHCP server. This sub-menu is exited by scrolling to the “Sel to go to Main Menu” screen and pressing SEL, or by pressing CABLE or NTWRK to exit to a test mode. 4.4 DHCP On/Off This is a simple on-off selection made using the SEL button. The last displayed state is the selected state. DHCP is a protocol negotiation used to automatically configure the IP parameters of the LanScaper™ on a specific LAN segment.
5.0 STATUS AND ERROR MESSAGES FOR NETWORK TEST MODES ARP received - In Validate Link mode, this status shows that the tester has detected another active LanScaper™ trying to start a PING conversation. This status flashes for a few seconds while the units negotiate an IP address they can use to PING each other. DHCP Request - In the PING test with DHCP On, the LanScaper™ displays this message on the first line while it is trying to get the required information from a DHCP server.
NIC Rx overrun - The Ethernet interface chip used in the LanScaper™ provides internal buffering for multiple packets. If new packets are received faster than they can be processed, the Ethernet chip discards the new packets and sets the Overrun error flag. The tester detects and reports this error. May be caused by excessive broadcast traffic on the LAN, or by externally generated packets addressed to the tester’s IP address.
Rtr must be on MyIP LAN segment - Displayed in Setup while setting the Manual Router IP address. The LanScaper™ requires that the Router be at an IP address on the LAN segment as defined by the Netmask and MyIP addresses. Setup will not allow the Router IP address to be set to an off-LAN address. Voltage Found, SEL Jack ID - The tester does not operate in Network modes when voltage, and possibly destructive power, is found.
6.0 INTERPRETING CABLE TEST RESULTS The PASS icon will be on if the cable has all pins properly connected per T568A/B. Neither icon will be on if the cable is cross-over (uplink) cable. The FAIL icon will be on if there is any other condition. See Figure 6.1, Examples of Wiring Errors. Definition of Errors - The three classes of faults discussed below are in order of severity. The severity has to do with the ability of a more severe error to mask lower severity errors.

Appendix A: Glossary of Networking Terms 10 Base-T - The earliest definition of Ethernet was for 10 Million Bits per second, 10 Mbps. The Ethernet specification defined several different cabling schemes, including T568A/B (4-pairs of wire) and coax wiring. The 10 in 10 Base-T defines 10 Mbps and the Base-T defines T568A/B, CAT3 cabling. 10 Base-2 defines 10 Mbps over coax. Note that the LanScaper™ PING mode works in 10 Base-T.
HUBs are typically older Ethernet devices that are 10 BaseT. Most 10/100 HUB like devices are now switches (see definition). LanScaper™ uses HUB as a definition for a specific Ethernet connection pin assignment that allows it to connect directly to a NIC device using a straight through cable. MAC = Media Access Control - Protocol defined for addressing network-interfaces on a unique basis.
Switch - Similar to a HUB, a switch is a multiple port Ethernet connection device that allows for multiple Ethernet devices to communicate between each other. Unlike a HUB, a switch has internal logic that determines which port a specific MAC address is found on, and once it has determined that, it only forwards traffic destined for that address to that port. This allows for fewer collisions on the LAN by not re-transmitting every packet on every port.
Appendix B: Internet Protocol Definitions ARP = Address Resolution Protocol - Used to determine Ethernet (MAC) address when a device starts to communicate with another. The IP address is known and a broadcast is used to request the specific IP addressed device to respond with its MAC address, so further communication can be specifically addressed between the two.
ISP = Internet Service Provider - Commercial supplier of access mechanisms for public access to the internet. LAN = Local Area Network - Connection mechanism for a business, home, school or any group of devices to communicate with each other. In the LanScaper™ case, it is a group of computers, printers, routers and possibly other devices connected by Ethernet. Distinct from the WAN due to the IP addressing in a “Subnet”.
