PST-7000 series user’s manual – USING THE PST SYSTEM

Basic Functions

In essence a programmable keyboard allows any sequence of letters, numbers

and other control functions to be assigned to a particular key. When that key is

pressed the keyboard issues key codes exactly as if the sequence had been typed at a

standard QWERTY computer keyboard. Any key position may be programmed with

any sequence, and the entire keyboard set of key sequences may be uploaded to and

downloaded from the host computer file system.

Furthermore, this programmable keyboard supports a lot of advanced

functions such as keyboard security lock-off, multi-page, multi-level, answer-back,

speed control of output, time control on output hold, software switch off and so on.

These advanced functions are illustrated in the “special features” section. There is no

size restriction other then up to 255 characters per key and up to 8KB total memory

size for all the key definitions.

Structure

To the left of the keyboard frame is the MSR section, beneath the front edge of

the keyboard frame is a front door in which, there is a connector for external keyboard

connection. These two ports share the same port as the programmable keyboard.

When the programmable keyboard locks off the keyboard port, any input from these

two devices is also blocked off to insure the system security.

At the top right corner of the keyboard frame there is a 6 position key-lock.

This electronic key supports the security lock off, answer back and the multi-page

function that expands the programming ability of KB112 to 5 x 112 (560 in total)

possible key definitions, and KB136 to 5 x 51 + 2 (257 in total).

Within the major portion of the keyboard frame is a 8 by 14 matrix allowing in

total 112 positions for the programmable keys in KB112. In KB136 this area is further

divided into 2 parts. The upper part is 3 by 17 matrix parogrammable keys and the

lower part works like conventional keyboard with 2 embedded page independent

programmable keys. The key layout of programmable keys may present versatile

pattern through use of single key, double key, quad key and blank key. For example,

use of blank keys may separate the whole area into several clusters for the

convenience of application. Use of double key or quad key giving a larger surface for
