  • Page 4: Section I. Introduction

    Section I. Introduction. Negotiation makes networks work. Twisted pair cable is the standard for local area networks (LANs). Its popularity stems from its ease of use, cost, speed and maybe, most importantly, adaptability. A 10 Base-T device, installed years ago, communicates with a new gigabit switch (1000 Base-T) because the standard that defines Eth- ernet LANs requires negotiation to a common speed and duplex.

    Section IV. Learning the Main Unit's Faceplate The TVR1000 Main Unit can be connected to a single port of any 10, 100 or 1000 Base-T device and it can be inserted inline between any two LAN devices without disrupting LAN communications. The Main Unit performs the bulk of the tests.

Understanding the use of the 10/100/1000 LAN Test’s three RJ45 jacks. These jacks and associated LEDs are the heart of the Main Unit’s ability to save you time with your LAN tasks.

    Single Port testing Use the Green jack to verify the device type as a hub/switch or a PC; the presence of Data, Link pulses and PoE; and the speed and duplex capability of the device. First, turn ON the TVR1000. Then, plug the LAN device into the Green jack.

  • Page 15: Inline Testing

    Inline testing Use the three jacks to determine the negotiated speed and duplex between any two LAN devices. The multiple jacks pro- vide both a straight thru and a crossover connection (if required). The TVR1000 must be ON before plugging in devices. Using the two RJ45 straight thru patch cables provided with the TVR1000, plug two LAN devices into the leftmost jacks (making a straight thru connection between the two devices).

Speed and Duplex are important considerations because two LAN devices will not to communicate unless they both are operating at the same speed and duplex.For more detailed information about Data and Link pulses see Appendix B.

    Section V. Learning the Remote Probe's Faceplate The TVR1000’s Remote Probe adds cable tracing and pairs testing capability to the TVR1000. It is used with the Main Unit’s Cable Tests jack. The Remote Probe traces cables and tests a cable's pair configuration by tracing signals placed on the cable by the Cable Tests jack (Main Unit).

If you are testing a device that is capable of multiple speeds and duplexes, all appropriate LEDs will light.

As an example, if one of the devices is 1000 MB/s, full duplex and the negotiated speed between the two devices is 100 MB/s, half duplex, you know that something is pulling the 1000 Base-T device...

If this is the case, unplug both devices from the TVR1000 and then test the devices individually using the Green jack. The device that does not show any activity on the LEDs is causing the problem.

INVERTED PAIRS: If any of the pairs are present but have incorrect polarity (i.e. the “1,2” pair is really “2,1”) the pair’s LED will light red. Inverted pairs can slow down or stop a link. PAIR NOT PRESENT: The LEDs will not light, if the pair does not exist or if the pair is shorted across itself.

    Appendix A. Wiring Primer. Twisted Pair Cable: Base-T LANs are based on a star topology (every PC on the network is linked to a central location). The central location is termed a hub or switch. The cabling is always twisted pair wire terminated with 8 position modular connectors (RJ45).

  • Page 41: Appendix B. 10, 100 And 1000 Base-T Basics

    Appendix B. 10, 100 and 1000 Base-T Basics Base-T LANs connect LAN devices (PCs, hubs and switches) to other LAN devices using twisted pair cable. The speed and duplex of the individual devices (and the proper cable) determine the per- formance of the LAN.
  • Page 42 "Hub", "Switch" and "PC" defined: A “PC” is a device that transmits on a pair of wires that use pins 1 and 2 (“1,2”). A “hub” and "switch" are devices that transmit on pins 3 and 6 (“3,6”). When the TVR1000 senses a link pulse or data packet, it lights the Data and Link LEDs on the faceplate to indicate its source (hub or PC) based on the above standard.
  • Page 43 some devices are programmable, allowing you to "force" their speed and duplex. "Forced" devices, likewise, may not send link pulses. Because the TVR1000 uses link pulses to determine the speed and duplex, if there is no link pulse, no speed LEDs will light. This does not mean that the devices cannot communicate.
