Solution 1009357.1 : Sun Fire[TM] 12K/15K/E20K/E25K servers: System Controller serial port configuration

Applies to:

Sun Fire 12K Server
Sun Fire 15K Server
Sun Fire E20K Server
Sun Fire E25K Server
Sun SPARC Sun OS

Goal

The serial port located on the System Controller for the 12K/15K/E20K/E25K servers can be connected to any other serial device, if the correct pin-out is used.
Below, are the pins and signals for the serial port.

Solution

Use the following diagram when creating a connection:

8 pins Mini DIN
------------------
Signal, pin number                    -----------
------------------                   /           \
DTR        1                        /  8   7   6  \
CTS        2                       |               |
TXD        3                       |  3   4     5  |
GND        4                       |               |
RXD        5                        \    1   2    /
RTS        6                         \           /
DCD        7                          -----------
NC         8
------------------

Examples:

3 wire serial null modem cable.
Use x-on,x-off (software handshaking)

DTR  1  <---------------------->   6, DSR
CTS  2  <---------------------->   7, CTS
TXD  3  <---------------------->   2, RX
GND  4  <---------------------->   5, GND
RXD  5  <---------------------->   3, TX
RTS  6  <---------------------->   8, CTS
DCD  7  <---------------------->   4, DTR
NC   8                             1, NC
