The keyboard connects to the main electronics cabinet through a shielded partially coiled cord and is detachable at the system cabinet only. The mouse plugs into either side of the keyboard. Ports are provided on both sides of the enclosure to allow access to left-handed and right-handed mouse connectors. The keyboard cord contains low voltage direct current power feeds and two serial links; one for the mouse and one for the keyboard. The keyboard serial link is bidirectional, allowing for control of indicator lights and other keyboard functions. Each time a key is pressed or released, a code is sent via the keyboard serial link. Every key has a different upcode and downcode. All keys function the same way, allowing the system software to use keys in any manner. Auto- repeat is the only function that treats keys differently. When auto- repeat is enabled, a subset of the keys repeat when held down. Multiple key presses/releases result in all key transitions being reported. EEEElllleeeeccccttttrrrriiiiccccaaaallll IIIInnnntttteeeerrrrffffaaaacccceeee The keyboard serial I/O interface uses RS423 levels and communicates asynchronously to the system at 600 baud. The format used is one start bit followed by eight data bits, an odd parity bit and one stop bit, with one byte sent per key up or down transition. The idle state and true data bits for the interface are Mark level or -5V, whereas false data bits and the start bit are spaces or ++++5V. The pin assignments for the keyboard connector on machines with DB-15 connectors are shown in the following table: KKKKEEEEYYYYBBBBOOOOAAAARRRRDDDD CCCCOOOONNNNNNNNEEEECCCCTTTTOOOORRRR PPPPIIIINNNNOOOOUUUUTTTT ________________________________ Pin Signal Description ________________________________ 1 GND Ground 2 GND Ground 3 GND Ground 4 KTXD Keyboard Transmit 5 KRCD Keyboard Receive 7 ++++12Vdc Power 8 ++++12Vdc Power 9 ++++12Vdc Power 10 MTXD Mouse Transmit 11 NC Reserved 12 NC Reserved 15 -12Vdc Power |||||||||||||| |||||||||||||| The pin assignments for the DB-9 keyboard connector on the Personal IRIS 4D/20 and 4D/25 machines are shown in the following table for both the CPU connector and the connectors on the keyboard itself.

The format used is one start bit followed by eight data bits, an odd parity bit and one stop bit, with one byte sent per key up or down transition. The MSB of the byte is a 0000 for a downstroke and a 1111 for an upstroke. Control bytes are sent to the keyboard with the same speed and format. The system software does all the processing needed to support functions such as capitalization, control characters, and numeric lock. Auto-repeat for a specified set of characters can be turned on or off by the system software by sending a control byte to the keyboard. When auto-repeat is enabled, a pressed key begins auto-repeating after 0.65 seconds and repeats 28 times per second. The keyboard initializes upon power-up. The configuration request control byte causes the keyboard to send a two-byte sequence to the system. The second byte contains the eight-bit value set on a DIP switch in the keyboard. All keyboard lights (if any; some newer systems have keyboards without user controllable lights) are controlled by the system software by sending control bytes to the keyboard to turn them on or off. Control bytes are also used for long and short beep control and key click disable. When key click is enabled, the keys click when they are pressed. The long beep duration is 1 second and the short beep duration is 0.2 second. There are three lights labeled NUM LOCK, CAPS LOCK, and SCROLL LOCK that are under software control. On older keyboards there are also four general-purpose keyboard lights labeled L1 through L4. The required keycode mappings and control byte formats are shown in the following tables. Note that the legend names prefixed by two asterisks are reserved and not implemented on the keyboard. Legend names prefixed by two exclamation marks do NOT have the auto-repeat enable capability. Legend names prefixed by two dollar signs do NOT have the key click enable capability.
