    • What's this?

    This is a collection of pinouts that I've gathered over the years. Hopefully this will help get the equipment connected.

    Below some of the signal abbreviations are defined:

    Signal Description Use Pin
    RI Ring Indicator Input 1
    DSR (DCD) Data Set Ready (Data Carrier Detect) Input 2
    RTS Request to Send Output 3
    GND Chassis Ground N/A 4
    TxD Transmitted Data Output 5
    RxD Received Data Input 6
    SG Signal Ground Reference 7
    CTS Clear to Send Input 8
    DTR Data Terminal Ready Output 9
    DCD (DSR) Data Carrier Detect (Data Set Ready) Input 10

    This is the wiring for an RJ45 ethernet cable on a 10 base T wiring system.

    The numbering on an RJ45 connector:
    Pin number and strand color for 10 base T
    1   TX +     Bl (Blue)   White / Orange
    2   TX -     O (Orange)   Orange
    3   RX +     K (Black)   White / Green
    4   N/C     R (Red)   Blue
    5   N/C     G (Green)   White / Blue
    6   RX -     Y (Yellow)   Green
    7   DET     Br (Brown)   White / Brown
    8   N/C    W (White)   Brown

    In an RJ45 to DB-style connector, the pins correspond to the following colors:
    1     Bl (Blue)   White / Orange
    2     O (Orange)   Orange
    3     K (Black)   White / Green
    4     R (Red)   Blue
    5     G (Green)   White / Blue
    6     Y (Yellow)   Green
    7     Br (Brown)   White / Brown
    8     W (White)   Brown
    Null Ethernet, using standard RJ ethernet cable.
    This allows back-to-back twisted pair tranceivers to work. (ie, to connect two systems to each other.)

    Or the following colors:

    1     Bl (Blue)   K (Black)
    2     O (Orange)   Y (Yellow)
    3     K (Black)   BL (Blue)
    6     Y (Yellow)   Orange

    Pin number and strand color for 10 base T

    1   TX +     White / Orange   White / Green RX +   3  
    2   TX -     Orange   Green RX -   6  
    3   RX +     White / Green   White / Orange TX +   1  
    4   N/C     Blue   Blue N/C   4  
    5   N/C     White / Blue   White / Blue N/C   5  
    6   RX -     Green   Orange TX -   2  
    7   DET     White / Brown   White / Brown DET   7  
    8   N/C     Brown   Brown N/C   8

    Data cables are straight through for DCE devices. When crimping RJ ends onto the cables, the following colors are assigned to the following pins on the connector (see above):

    In general, holding the connector in your hand, tab side down, open end towards you, and insert the stripped cable with the *blue* wire on the left, except for RJ11 4-wire connectors, which has *yellow* on the left.

    Mini-DIN-8 serial port connectors are found on the Personal IRIS 4D/30, 4D/35, Indigo, Indy, and Indigo2. They are also found on the Origin 200 and Origin 2000 systems, used for the MMSC/System controller ("Aux") port. The pin assignments are: 

                      ---------
                  / 8  7  6 \
                 (  5  4  3  )

      5   RD   Receive Data
      6   RTS   Request To Send
      7   DCD   Data Carrier Detect
      8   SG   Signal Ground

    Since there is no such thing as a RJ-MiniDIN-8 adaptor, an SGI P/N X5-9to8 pigtail is used to give a female DB9 on systems with Mini-DIN-8 connectors.

    Mini-DIN-6 P/S2 keyboard connectors are found on Indigo, Indigo2, Indy, O2, Octane, and Onyx systems. Note that Indigo systems use the same connector but a different pinout -- see below for that pinout.

    The pin assignments for the system keyboard connector are shown in the following table:

    Older SGI systems used a DB15 connector for the keyboard and mouse, with either a DIN6 or DB9 connector at the keyboard end.

    SGI P/S2 Keyboard and Mouse to RJ45 plug, using (2) mini-din6 connectors to (1) RJ45 plug.
    Use to extend mouse & keyboard connections with RJ45 cable. ONLY for SGI systems that have P/S 2 compatible ports (Indy, Indigo2, O2, etc).

    This is a "Y" cable; two mini-din6 connectors are wired to one RJ45 plug. A pair of adaptors is needed, one mini-din6 female set, and one mini-din6 male set. Custom made by Anixter 408/435-1212, but SGI I/S stocks them internally- contact alex@csd.sgi.com. $20.75 each, so pair is $41.50. Mark Aubin aubin@asd.sgi.com

    Most Challenge L and XL systems have a front panel System Controller DB9 available. However, early systems were not shipped with the front plate to present a female DB9. There may be a small ribbon cable with an IDC end (edge row connector) available behind the access panel; if not, you'll have to take the back skins and panel off (where the power cord plugs in) to get access to the IDC socket off the backplane. Anyhow, here's the pinouts for the IDC connector:

    Annex 2 Connectors

    An Annex 2 uses standard telco (PBX) 50 pin connectors. (Centronics 50 pin connector). Each connector holds eight (8) terminal lines, like so:

      PBX #   Signal
      1   DTR
      2   GND
      3   N/C
      26   TXD
      27   RXD

    Modular adapters (Ortronics' P/N OR-8120M25-8/6) are used to adapt the 50pin PBX connector to eight (8) six pin RJ45 plugs. Each 6 pin RJ45 plug has the following pinout:

      RJ45   PBX #   Signal
      1   28   CTS
      2   27   RxD
      3   1   DTR
      4   26   TxD
      5   2   GND
      6   3   N/C

    Connecting a 6 conductor straight through RJ45 data cable from this plug to a standard RJ45 to DB-style connector (see above) yields the following color / signal table. THIS IS THE IMPORTANT TABLE!

      RJ45 #   Signal   Color
      1   8 PIN only   Bl (Blue)
      2   CTS   O (Orange)
      3   RxD   K (Black)
      4   DTR   R (Red)
      5   TxD   G (Green)
      6   GND   Y (Yellow)
      7   N/C   Br (Brown)
      8   8 Pin only   W (White)

    The console connection for an Annex 2 is on port 1. Use one of the below connectors to hook it up to the desired gadget.

    Annex 3 Connectors

    An Annex 3 uses standard telco (PBX) 50 pin connectors. (Centronics 50 pin connector). Each connector holds six (6) terminal lines, like so:

      PBX #   Signal
      1   DCD
      2   GND
      3   DSR
      4   RTS
      26   RxD

    ----------------------------=======

    Modular adapters are used to adapt the 50pin PBX connector to six (6) eight pin RJ45 plugs. Each 8 pin RJ45 plug has the following pinout:

      RJ45   Color   Signal   PBX #
      1   Bl (Blue)   TxD   27

    SGI "Etherlite" terminal servers are remarketed products from Central Data Systems. They are 8, 16, or 32 port ethernet based serial ports, connected "directly" to the SGI host system via a kernel driver and some system daemons -- they give normal looking devices as /dev/tty[mdf][\d][\d+]. You need the 'el_serial' inst package installed to use these servers. Good additional information on the drivers is at http://www.digi.com.

    SGI cables, using rj45 connectors.

    Using straight-thru 8-pin RJ45 cables and the various pinouts listed in this section, it is possible to mix-and-match the connectors to what is needed. Connect two "modem" adaptors (one DB25 Male for the modem, one DB9 Male for the SGI) for a modem cable, or exchange one "modem" adaptor for a "null" adaptor to create a null modem cable to connect a terminal to an SGI, or two SGI systems back-to-back. Since there is no such thing as a RJ-MiniDIN-8 adaptor, an SGI P/N X5-9to8 pigtail is used to give a female DB9 on systems with Mini-DIN-8 connectors.

    SGI Modem cable, using rj45 connectors. Use one of each:
