   100 Mbps Cabling Specifications

   Specifications and recommendations for Twisted-Pair Ethernet
   ============================================================
   RJ45 cabling is also known as Twisted-pair Ethernet (TPE) or Unshielded
   twisted pair (UTP), and 10BASE-T.

   This document covers the following topics:

   -  Recommended cables

   -  Cable and connector pinouts

   -  Link integrity

   -  Common problems

   For more information on the 100BASE-TX specification, ISO/IEC 8802-3,
   contact your local network supplier or call the IEEE at 800-678-IEEE.

   Recommended cables
   ==================
   The cable must comply with the IEEE 802.3 10BASE-T standard for 2-pair,
   Category 5, UTP cable.

   The cable between the computer and the hub must be less than 100 meters
   long.

   This UTP cable works well:

   Manufacturer       Model number         No. of pairs
   ------------------------------------------------------
   Belden             1588A                     2  

   Cable and connector pinouts
   ===========================
   If you need to repair a cable or provide connectors for UTP cable, wire
   straight through as shown in the following table.

   Function    Pin#               Pin#
   -------------------------------------
     TX+        1    <-------->    1
     TX-        2    <-------->    2

     RX+        3    <-------->    3
     RX-        6    <-------->    6

   Use only four of the eight pins. Pins 1 and 2 must be a pair, and pins 3
   and 6 must be a pair.

   To allow for a straight-through cable, the hub provides an internal
   transmit/receive crossover function. This means the transmit circuit of
   the network card is connected to the receive circuit of the hub and vice
   versa.

   Pin name and function:

   1  Transmit Data Plus (TD+). The positive signal for the TD differential 
      pair. This signal contains the serial output data stream transmitted 
      onto the network.

   2  Transmit Data Minus (TD-). The negative signal for the TD differential 
      pair. This contains the same output as pin 1.

   3  Receive Data Plus (RD+). The positive signal for the RD differential 
      pair. This signal contains the serial input data stream received from 
      the network.

   4  Not used.

   5  Not used.

   6  Receive data minus (RD-). The negative signal for the RD differential 
      pair. This signal contains the same input as pin 3.
 
   7  Not used.

   8  Not used.

   Link integrity
   ==============
   There are three LEDs on the EtherExpress PRO/100 adapter: A LNK light for
   link, an ACT light for activity, and a 100 light which indicates a 100
   Mbps connection.

   Note: The ACT LED indicates that there is read/write activity on the
         network. It doesn't always mean there is activity on the adapter.

   Common problems
   ===============
   A hub can't detect a workstation
   --------------------------------
   This is often the result of a crossed wire in the cable or wiring closet.
   Make sure the wiring is correct.

   Workstations can't connect to the network
   -----------------------------------------
   Make sure hub port is configured to the correct speed. Also try resetting the 
   concentrator or hub or turn the power off and on.

   Polarity problems
   -----------------
   A common problem in 10BASE-T wiring is crossing the positive and negative
   phases of the transmit or receive signals (for example, crossing pins 1
   (TX+) and 2 (TX-)). EtherExpress PRO/100 adapters automatically detect this 
   problem and adjust for it internally.

   Even though the current EtherExpress PRO/100 adapters can take care of
   this crossover for you, it's best to check your wiring and correct this
   problem if you find it.

   Connecting two workstations without a hub
   =========================================
   10BASE-T uses a star topology. This means there is a hub or concentrator
   in the center of a star, and each workstation or server is connected to
   this hub.

   For test purposes, you can directly connect two workstations or a
   workstation and a server without using a hub. This requires a special
   cable that incorporates the crossover function described earlier in this
   document.

   Function    Pin#               Pin#   Function
   --------------------------------------------------
   TX+        1    <-------->   3        RX+
   TX-        2    <-------->   6        RX-

   RX+        3    <-------->   1        TX+
   RX-        6    <-------->   2        TX-

   NOTE: This is not an IEEE supported configuration and should be used for
         test purposes only. Be sure to maintain pairs when building this
         cable - 1 & 2 are a pair, and 3 & 6 are a pair.
