Serial Cables and Converters

This section contains cable pinout information for serial cables that you can connect to your O2 workstation. It also describes Silicon Graphics' serial port converters. The following topics are covered:

Printer/Dumb Terminal Serial Cable

For serial printers and dumb terminals, use a 3-wired standard PC cable. Table A-11 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, from the Toolchest choose Help > InfoSearch and select “Man pages.” Or place the cursor in the console window and type

man serial

Table A-11. Cable Pinout Assignments for the Printer/Dumb Terminal Serial Cable

Signal Description	Pin Number DB9 Connector (Female)	Pin Number DB-25 Connector (Male)
	1	NOT CONNECTED
RXD	2	2
TXD	3	3
	4	NOT CONNECTED
GND	5	7
	6	NOT CONNECTED
	7	NOT CONNECTED
	8	NOT CONNECTED
	9	NOT CONNECTED

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-12 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. Devices like serial printers and dumb terminals that do not need RTS flow control can still be used with this cable provided that a null modem adapter is added to one end of the cable. You can purchase the full-handshake PC modem serial cable from Silicon Graphics 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, from the Toolchest choose Help > InfoSearch and select “Man pages.” Or place the cursor in the console window and type

man serial

Serial Port Converters

The O2 workstation's serial ports conform to the PC standard pinout for EIA standard RS-232 signals. The transmit and receive circuits are also capable of higher speed signalling according to the EIA RS-423 standard. In addition, you can convert these signals to support other interfaces.

Silicon Graphics offers two converters: one for the RS-422, commonly used for video deck control, and an Apple Macintosh^® to MIDI converter for the RS-422-like signalling used by MIDI devices to connect to Apple Macintosh serial ports.

RS-422 Converter (DB-9 Female) For Video Deck Control

The Silicon Graphics RS-422 Converter takes the O2 workstation's RS-232 Transmit Data and Receive Data signals and converts them to SMPTE 207M-compatible RS-422 for video deck control.

Table A-13 shows the pinouts for the O2 workstation end. Table A-14 shows the pinouts for the video deck end.

Table A-13. RS-422 Converter (DB-9 Female): Workstation End

Workstation Signal Description	Pin Number	Voltage With Regard to Ground Received From or Supplied to Workstation
DCD	1	Passed through from RS-422 spare
RXD	2	Supplies -5V typical low, +5V typical high (RS-423)

Frame GND	9	Not connected

Macintosh to MIDI Converter (DB-9 Female to MiniDIN-8 Female)

The Silicon Graphics Macintosh to MIDI converter takes the O2 workstation's RS-232 Transmit Data and Receive Data signals and converts them to RS-422-like signalling used by MIDI devices to connect to Apple Macintosh serial ports.

Table A-15 shows the pinouts for the O2 workstation end. Table A-16 shows the pinouts for the MIDI interface end.
