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

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

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.

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.

O2 Camera Technical Specifications

Table A-17 below lists O2Cam's technical specifications.

Table A-17. O2Cam Technical Specificatons

Sensor

512 x 480 NTSC Color CCD, 1/3” format

Standard lens

F2.0, 6mm with M11 screw mount and built-in IR filter.

Output format

Outputs 640 x 480 Square Pixel NTSC frames @ 29.97Hz (780 x 525 total frame), as 422YCrCb pixels with 1 byte luminance followed by 1 byte chrominance, on a 24.5 MHz interface clock.

Automatic Gain Control

Automatic Gain Control adjusts gain to achieve average output brightness. AGC can be activated or overridden (via new gain value) from workstation.

Shutter speeds

Selectable from 1/60 through 1/10,000 second

Auto white balance

Software initializes camera at workstation power on and loads red and blue balance, red and blue saturation, and gamma values that are balanced for offices with or without windows, with incandescent and/or fluorescent lights. User can make additional white balance adjustments with the digital media software.

Gamma correction

Gamma factor of 0 or 255 can be loaded into camera by workstation at any time.

Push button

The control button drives the GPIBIN line on the 68-pin connector. While button is up, voltage is high; while button is down, voltage is low.

Power requirements

1W @ 5V (200mA), 1W @ 12V (80mA), and 12 mW @ -12V (1mA) are provided by the workstation. These are maximum amounts available to the camera, actual consumption should be lower.

LED indicator

On/off state is controlled by the workstation via I2C.

Workstation interface

DVCI uses 68-position 0.8 mm Champ connector on far end of attached 8 ft cable. Video is transmitted at TTL levels, 1 byte wide plus hsync and vsync. All camera parameters are accessed and controlled by the workstation via I2C. Workstation provides 5V power.

Focus adjustment

Focal distance from 3” to infinity with standard lens.

Microphone

Built-in directional microphone and preamp produces a monoaural, single-ended line level signal.
