    For detailed description of each function, see the Functional Description section. Interpreting Cable Test Results and Error Messages sections are useful reference sections. 1.5 Network Connectivity Negotiation using Fast Link Pulses to report advertised Ethernet capability. LanScaper™ also supports a modified version of auto MDI/MDI-X to allow for connection to a HUB, switch or NIC with a straight through cable.

    LanScaper 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.

  • Page 7: To Change Ping Addressing Mode

    LanScaper 2.8 To Change PING Addressing Mode - Other options are changed similarly. 1) Turn on LanScaper™ by pressing PWR button and press the middle of the CABLE/NTWRK button, which is marked SETUP. The percent battery remaining screen will appear briefly. 2) Press down arrow button three times, DHCP On or DHCP Off should be displayed.

  • Page 8: Jack Id

    LanScaper 3.2.1 Jack ID - The Jack ID test identifies what equipment, if any is, connected to the other end of the jack or cable being tested. The test first looks for voltages being present on the connector pins. If voltages are found in typical phone locations, tests for current levels and dial tone are run. From these tests, the LanScaper™...

  • Page 9: Tone Generator

    LanScaper 3.2.4 Tone Generator - The tone mode generates audio tones for use with tone tracers on all pairs, a selected pair or a selected pin. The signal generated on a pair has the signal on one pin and the complement of the signal on the other pin of the pair, yielding a nominal 10 volts peak-to-peak across the pair.
  • Page 10 LanScaper (ARP) request directed to its proposed MyIP address. A response to the ARP tells the tester that some other device on the LAN is already using that IP address. The DHCP protocol specification (RFC 1541) says that in the case a server offers an address already in use, the receiver of that address should reject it and request another.
  • Page 11 LanScaper The tester sends out an ARP packet directed to the Router, and needs a response from the Router informing the tester of the Router's MAC address. During this phase, “ARP” will flash under the “Rtr” acronym. If no response is received to the ARP request, the tester will repeat the request at varying intervals (1-3 seconds).

  • Page 12: Validate Link

    LanScaper 3.3.3 Validate Link - This mode allows two LanScaper™ testers to be connected directly to each other on a cable with no other equipment required. No special configuration of the testers is required other than to put them into the test modes as described. This allows a cable run to be verified after installation.

  • Page 13: Ping Setup Sub-Menu

    LanScaper Each of the four decimal numbers separated by periods represents one hexadecimal byte of the four byte IP address, and can only take on the values between 0-255. Each digit in the decimal number can only be set to a value valid for that position. Thus, the high order digit in any of the decimal numbers can only be set to 0, 1, or 2.

  • Page 14: Dhcp On/Off

    LanScaper 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. With DHCP On, the next time the PING test is started, the tester will request IP parameters it needs for LAN communication from a DHCP server on that LAN segment.
  • Page 15 NIC init err - The Ethernet interface chip used in the LanScaper™ reported a problem to the CPU during internal initialization. May be caused by a hardware problem inside the tester. NIC Rx overrun - The Ethernet interface chip used in the LanScaper™ provides internal buffering for multiple packets.

    LanScaper 6.0 INTERPETING 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.

    LanScaper 7.0 MAINTENANCE 7.1 Battery Replacement - as practical. The testing results will become unreliable when the battery reaches about 5.0 volts. To replace the battery: 1) Be sure tester is off. 2) Remove rubber battery cap by pressing on edge of the cap with the heel of the hand until the cap pops off.

  • Page 19: Appendix A: Glossary Of Networking Terms

    LanScaper 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.
  • Page 20 LanScaper = Network Interface Card - Typically an option card plugged into a PC card slot that provides an Ethernet interface for that PC. LanScaper™ uses the term NIC to define the connector pin out that allows for direct connection to a HUB device using a straight-through cable. Polarity - Ethernet transmit and receive driver chips use differential voltages to improve noise immunity.

  • Page 21: 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.
  • Page 22 LanScaper PING = Packet INternet Groper - A simple communication protocol (ICMP Echo) used to request an echo back from an addressed device (target). The LanScaper™ uses this to verify IP connectivity between itself and another device. Router = Gateway - If a device is attempting to communicate with an IP address, and it finds that the target is not on its local network (by comparing the target address with it's own address and the Netmask) the device must forward it's request to a router.
