What is MID?
  • Computer peripheral unit
    • Input device (keys, MCR)
    • Output device (LCD)
    • Input/Output device (ICCR)
mid is composed of
MID is composed of
  • One master module
    • Communicates with PC
    • And with all rest slave modules
  • And one or more Slave modules
    • Controlls its unit
    • Detects pressed keys and sends this information toward PC
    • Gets the command from master module what to display on LCD and executes the command
    • Up to 14 modules could be connected
      • Internal modules (red connectors + 6 pin flat cabels)
      • Externa modules (special external cable– up to 1,2 m)
how to assemble mid 2
How to assemble MID 2
  • Not more than 256 keys all together
      • Even MCR, iButton, Keylock have virtual keys and these keys are also includein in this 256 array
  • Keyboard information
    • In MIDWIN/MIDDOS with the command Keyboard->Info
    • Shows the composition (which moduls) and
      • Chip versions (very useful when troubleshooting)
mid is programmable 1
MID is programmable 1
  • Advantages
    • One key substitutes sequence or combination of keys
    • Mouse is not needed
    • Higher entering speed
    • No need for teaching of operators
  • What is programmable by special modules (MCR, iButton, …)
    • Header in Terminator
      • Kbd-pc: header – content of the card - terminator
      • Sistem can distinguish between other keys and card
    • Working mode

MID is programmable 2
  • The settings are stored in Master module
    • Slave module sends just the information which key has been pressed
    • The content stays when it is programmed
    • It can be reprogrammed
    • Can be programmed at one place (e.g. Tipro) and used at another place or computer
  • Memory size is 8KB, what represents aprox. 3000 characters (depends on content, configuration, …)

  • Special program, called Download softver
    • MIDDOS and MIDWIN
use of mid 2
Use of MID 2
  • POS (Point Of Sale) environment
    • Ene key represents one item
      • Gastronomy
      • Shops
      • Kiosks
      • Movie centers
  • Industry
    • Industrial printers
    • Machine control
    • Telephone exchange
use of mid 3
Use of MID 3
  • Special office applications
    • AutoCAD
    • Manager programs
    • Bookkeeping
use of mid 4
Use of MID 4
  • Everywhere
    • Where not many commands are needed
    • Where is risk to make mistake
    • Where fast and easy entry is essential

Description of modules 1
  • Master module
    • Different versions
      • AT/PS2 outputand AT/PS2 input for standard keyboard (also called secondary kbd.)
      • AT/PS2 & RS232 outputs and AT/PS2 input for standard keyboard
      • AT/PS2 & RS232 outputs, AT/PS2 input for standard keyboard and RS232 input for external barcode scanner
      • Additional connector for external modules (special cabel; up to 1,2 m)
description of modules 2
Description of modules2
  • Key moduls
    • Just keys
      • XY matrixes or combination with alphanumerical part (PM and QM)
  • Every key
    • Represents one item
    • Substitutes key combination
    • Substitutes mouse
description of modules 3
Description of modules3
  • Key modules (cont.)
    • With keylock
      • Some functions can be restricted with keys

description of modules 6
Description of modules6
  • Connection of external bar code scanner
      • barcode scanner – Metrologic, Symbol, …
      • PS2 scanner is connected as standard secondary keyboard - MID only forwards codes
      • RS232 scanner is connected to special master(variants MR0Bx)
        • MID collects scanner data and transmits them toward PC

Connection to the PC 1
  • AT/PS2 only
    • MID is above all input device
    • Data capturing is very well supported
    • MID could be composed also of output modules (LCD, ICCR); in this case data transmition rate is lower
connection to the pc 2
Connection to the PC 2
  • AT/PS2 and RS232
    • Input and output modules
    • Both communication channels could be used simultaneously
connection to the pc 3
Connection to the PC 3
  • RS232 only
    • Device without AT/PS2 port
    • Additional power supply
