**** RJ-45 Information ****
*****************************
RJ45 to DB9/25 connectors (colors based on GEC):
Standard - including SGI:
Standard Null IBM-noloop
-------- ---- ----------
TD 2) * Yellow Green Yellow
RD 3) * Green Yellow
RTS 4) White/Grey Brown
CTS 5) Brown White/Grey
DSR 6) Blue Black
SG 7) * Red Red
DCD 8) Orange Orange
DTR 9/20) Black Blue
* Basic RS-232 required connections
RJ45 cable & wire colors (colors are the same both for cable and in
connectors - if cable blue is on right looking at plug with
tab down). I have seen two different color schemes in the
8-line modular cable, mostly the same, execpt tan vs. white.
1 - blue DSR
cable end 2 - tan/white DCD (orange in connectors)
|-----------------| 3 - black DTR
| 8 7 6 5 4 3 2 1 | 4 - red SG
|-----| |-----| 5 - green RD
|-----| 6 - yellow TD
7 - brown CTS
8 - grey RTS
RJ45 NULL cable:
To wire a NULL RJ45 cable, use standard colors on one side, and
swapped colors on the other:
Standard Null
-------- ----
1) DSR - Blue DTR - Black
2) DCD - Tan/White DCD - Tan/White
3) DTR - Black DSR - Blue
4) SG - Red SG - Red
5) RD - Green TD - Yellow
6) TD - Yellow RD - Green
7) CTS - Brown RTS - Grey/Orange
8) RTS - Grey/Orange CTS - Brown
RJ45 adaptor part numbers:
9 pin: male - 45-0650 female - 45-0655
25 pin: male - 45-0620 female - 45-0625

Machines that use the Real Standard:
SGI
Extron 200 Series Matrix Switcher (uses Simple/Null)
Electorhome Marquee 8x00 projectors (uses Simple/Null)
...
Machines that use non-standard connections (see below):
PCs
Ascension Flock of Birds
Lightwaves (even the models for SGI)
SGI - 8 pin minidin
Mac - 8 pin minidin
Logitech Tracker - 7 pin minidin
SGI - 8 pin large din w/ power
Made-up RJ45 connections:
SGI keyboard
Stereo IR transmitters
------------------------------------------------------------------------
PC (486) connector (eg. Wand PC cable)
9 pin female
2 - yellow (RD)
3 - green (TD)
4 - 6 (?)
5 - red (SG)
6 - 4 (?)
7 - 8 (?)
8 - orange (DTR)
------------------------------------------------------------------------
PC (XT etc) connector (eg. CAT-PC cable)
25 pin female
this may be standard, need to check
------------------------------------------------------------------------
Ascension DB-9 connector (from RJ45 colors)
9 pin male
2 - green (TD)
3 - yellow (RD)
5 - red (SG)
-------
4 - grey (RTS) these two optional - needed for reset
9 - black (DTR)
------------------------------------------------------------------------
Lightwave DB-9 connectors (from RJ45 colors)
9 pin male/female
The dumbest possible connections - make no sense whatsoever.
Mostly the PC method, except with TD & RD reversed - and this
is for the SGI version of their box. And, since the lightwaves
require that the data be moving in a specific direction (unlike
copper) - this matters!
NOTE: a Null-Simple-PC connector on both ends will probably work
for most requirements on both the Serial and Aux ports.
Serial Port:
1 - N/A (Stereo Sync - ttl)
2 - green (RD - duh, this s/b the TD line)
3 - yellow (TD - duh, this s/b the RD line)
4 - black (DTR - terminal needs this for some reason)
5 - red (SG - duh, wasn't this for the SGI box?)
-------
6 - blue (DSR - optional?)
7 - white/g (RTS - optional?)
8 - brown (CTS - optional?)
9 - N/A (provides +V on the reciever box for stereo)
-------
x - orange (DCD - no connection)
Use pins 1 & 5 to make coax stereo output (1 to inside, 5 to outside)
Aux Port:
2 - green (RD - duh, this s/b the TD line)
3 - yellow (TD - duh, this s/b the RD line)
5 - red (SG - duh, wasn't this for the SGI box?)
* 7 - black (DTR - terminal needs this for some reason)
-------
...
* - different from Lightwave Serial port (why?)
