ppppcccckkkkeeeeyyyybbbbooooaaaarrrrdddd((((7777)))) ppppcccckkkkeeeeyyyybbbbooooaaaarrrrdddd((((7777)))) NNNNAAAAMMMMEEEE pckeyboard - keyboard specifications DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN The Indy, Indigo2, O2, OCTANE and Onyx2 systems use an industry-standard PC-compatible keyboard with a PS/2 style (6 pin mini-DIN) connector. The keyboard connects to the back of the system unit with a shielded partially coiled cord and is detachable at the system cabinet only. The system communicates with the keyboard via a clocked serial protocol. SGI uses keyboard scan code set 3, which sends a scan code on key press and a "break" code followed by repeating the scan code. Every key has a unique scan code. All keys function the same way, allowing the system software to use keys in any manner. CCCCoooommmmppppaaaattttiiiibbbbiiiilllliiiittttyyyy Most PC keyboards work out of the box (they may require a 5 pin DIN to 6 pin mini-DIN) if they match the normal 101-key layout. Keyboards with different or extra keys may require tuning of keyboard map. The following keyboards have been tested (some only briefly) and seem to function correctly: SGI Indigo keyboards (US and several international models) SGI Indy keyboards (US and several international models) Kinesis ergonomic keyboard, Model 100, 110, 120 and 130 Comfort Keyboard System IBM PS/2 Model M (P/N 1391401) IBM 101 Key Keyboard with Trackpoint II - PS Style (P/N 92G7461) Microsoft Natural Keyboard Compaq enhanced II keyboard, domestic/101 Qtronix QX-601R Some keyboards that are known not to work, or require minor changes: Lexmark M13 (Select_ease) - Does not always power-on correctly. See nogfxkbd option in _p_r_o_m(1m). Data Hand - Newer versions are reported to work, but older ones do not. PC Concepts Ergonomic - does not implement scan code set 3. EEEElllleeeeccccttttrrrriiiiccccaaaallll IIIInnnntttteeeerrrrffffaaaacccceeee The PC keyboard uses a clocked serial I/O interface. The format used is one start bit (always false) followed by eight data bits, an odd parity bit and one stop bit (always true). The true data bits are at least +2.4V and less than +5.5V, while the false data bits are at least 0V and less than +0.7V. While inactive, the clock and data lines are held high, which indicates the keyboard has the right to send data. When the system wishes to send data to the keyboard it holds the clock low and then proceeds with its transmission. PPPPaaaaggggeeee 1111 ppppcccckkkkeeeeyyyybbbbooooaaaarrrrdddd((((7777)))) ppppcccckkkkeeeeyyyybbbbooooaaaarrrrdddd((((7777)))) The pin assignments for the system keyboard connector are shown in the following table: ------ / 5 3 \ | --- 1 | | --- 2 | \ 6 4 / ------ Pin Assignments ___________________ Pin Description ___________________ 1 Data 2 Reserved 3 Signal Ground 4 Power +5V 5 Clock 6 Reserved |||||||| SSSSooooffffttttwwwwaaaarrrreeee IIIInnnntttteeeerrrrffffaaaacccceeee System software interfaces to a PC keyboard controller that maintains the clocked serial protocol with keyboard. SGI uses keyboard scan code set 3, which sends a scan code on key press and a "break" code followed by repeating the scan code. The system software does all the processing needed to support functions such as capitalization, control characters, and numeric lock. Variable speed hardware auto-repeat for a specified set of characters is supported and is used in standalone mode, while IRIX manages auto-repeat in software. The default hardware auto-repeat begins after 500 milliseconds and repeats at a rate of 10.9 characters per second. There are three lights labeled NUM LOCK, CAPS LOCK, and SCROLL LOCK that are under software control. The scan codes sent by the standard 101 key American keyboard are in the following tables. Note that the legend names prefixed by two asterisks are only found on 102 key International keyboards.
