I/O Port Specifications

This section contains specifications and port pinout information for the I/O ports of the workstation. The ports are discussed in the following sections:

Ethernet 10-Base-T/100-Base-T Port

The workstation auto-selects the Ethernet port speed and type (duplex versus half-duplex) when the workstation is booted, based on what it is connected to. Figure A-1 shows the Ethernet port.

Serial Ports

The workstation features two 9-pin serial ports. These ports are capable of transferring data at rates as high as 230 KB/s. Other features of the ports include:

  • Programmable data, parity, and stop bits

  • Programmable baud rate and modem control

Serial Cables and Adapter Specifications

This section contains cable pinout information for serial cables that you can connect to your workstation. It also describes SGI serial port converters. The following topics are covered:

Printer/Dumb Terminal Serial Cable

For serial printers and dumb terminals, use a 3-wire standard PC cable. Table A-6 shows the cable connector pinout assignments for this cable.

Note: For a 3-wire cable and no hardware flow control modem, you must use the /dev/ttyd* command devices in the configuration files. For more detailed information, see the serial man page. To access the man page, select Help > Man pages from the Toolchest or place the cursor in the console window and type man serial.

PC Modem Serial Cable

Use a full-handshake (includes RTS and CTS) PC modem serial cable for a modem with RTS/CTS flow control. Table A-7 shows the cable connector pin assignments for this cable.

You can use this cable for all serial devices except those that do not need RTS flow control. If you add a null modem adapter to one end of the cable, you can still use it with devices like serial printers and dumb terminals that do not need RTS flow control. You can purchase the full-handshake PC modem serial cable from SGI or your local service provider.

Note: If you are attaching a modem with modem signals and RTS/CTS flow control, you must use the /dev/ttyf* command devices in the configuration files. For more detailed information, see the serial man page. To access this man page, select Help > Man pages from the Toolchest or place the cursor in the console window and type man serial.

Serial Port Adapter Cables

The workstation's serial ports conform to the PC standard pinout for EIA standard RS-232 signals.

The purpose of the adapter cable is to allow the workstation to use standard PC serial devices. Table A-8 shows the adapter cable pinout for a standard PC or Macintosh serial port.
