Hi All,

I am trying to wire the following adapters to obtain a teminal
connection to a sun utlra 60 from the serial port of a PC laptop.

I have tried the following config suggested on a non-sun-afilliated
website, which alas did not work:

Null DBMALE 25

Position Color
1 Red
2 Yellow
3 Black
4 White
5 Blue
7 Green
8 Orange
20 Brown

RJ45 connector

Cat 5

RJ45 connector

STRAIGHT DB-9 Female
Position Color
1 Red
2 Yellow
3 Black
4 Orange
5 Green
6 Brown
7 Blue
8 White

I have had another goodle around and found the following suggested as
well:

25 pin 9 pin
pin 1 GND - pin 1 GND
pin 2 TXD - pin 3 RXD
pin 3 RXD - pin 3 TXD
pin 4 RTS - pin 8 CTS
pin 5 CTS - pin 7 RTS
pin 7 gnd - pin 5 gnd
pin 6 DSR - pin 4 DTR
pin 20 DTR - pin 6 DSR


Could anyone confirm for me the needed wiring to connect a DB9-Female
(PC) to DB25-Male (Ultra 60). I am using the modular adapters that
allow you to simply insert each pin into each numbered hold on the
connector.

Many thanks if anyone can help here. Oh and for the record the box was
booted without a keyboard connected and can be reached via ssh/telnet
over ethernet. I have tried minicom from linux and secureCRT from
windows.

Baud-9600
Port-COM1
DataBits - 8
Parity-None
StopBit-N

Cheers,
Luke

This came up a couple of weeks ago. Several web links.
I'm surprised your google didn't find it?

You have a typo here. 2 connections to pin 3 on 9-pin? Check your source!

I usually use stock/standard adapters, esp. for testing out new stuff. I
would use standard 25-pin to 9-pin adapter, together with a null modem
adapter (either 25-pin or 9-pin), and standard cables. Why screw around.
The local Staples (business supply) were clearing this kind of stuff out
at a few bucks per... I picked up some extras. Always good to have.

I want to use cat 5 so that I can be to use different lengths in all
different situations (data centres) - so its handy to have serial
connectors to rj45.

Will look into the staples thing thought
