   10 Mbps Cabling Specifications
                                                                    
   Specifications and recommendations for Twisted-Pair Ethernet
   ============================================================
   NOTE: For 100 Mbps operation, refer to the 100 Mbps Cabling
         Specification.

   RJ45 cabling is also known as Twisted-pair Ethernet (TPE), Unshielded
   Twisted Pair (UTP), and 10BASE-T.

   This document covers the following topics:

   -  Recommended cables

   -  Cable and connector pinouts

   -  Connecting two workstations without a hub

   -  Link integrity

   -  Common problems

   For more information on the 10BASE-T specification, contact your local
   network supplier or call the IEEE at 800-678-IEEE.

   Recommended cables
   ==================
   The RJ45 connector can use 22, 24, or 26-gauge UTP cabling. The cable
   must comply with the IEEE 802.3 10BASE-T standard for Category 3, 4,
   or 5.

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

   These UTP cables work well:

   Manufacturer       Model number         No. of pairs
   ------------------------------------------------------
   Belden             9562                 2
   Data Set           2402                 4
   Belden             9566                 6

   Silver Satin is not within the 10BASE-T specification and may not work or
   may work intermittently.

   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. 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. The negative signal for the RD differential pair.
      This signal contains the same input as pin 3.

   7  Not used.

   8  Not used.

   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.

   Link integrity
   ==============
   There are three LEDs on the PRO/100 ISA 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
   -----------------------------------------
   Reset or power off/on your concentrator or hub.

   Polarity problems
   -----------------
   A common problem in 10BASE-T wiring is crossing the positive and negative
   phases of the transmit and 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.
