These instructions assume you are using the styling module available for this display.

  1. In Printer Definitions, define a local printer for each display.
  2. Modify the Print to command in the GDU chain if the display name is other than GDU.
  3. Add additional Print to commands to the GDU chain if more than one GDU exists.
  4. Edit the GDUHELLO template as desired for the specific restaurant.
  5. In the startup chain, put Do Template GDUHELLO followed by Print To GDU.
  6. Save the GDU chain as the ORDERITM chain, or if one already exists, copy the commands into that chain. In Local Options put Chain To ORDERITM for the Order Item Instruction.
  7. On any Cancel button, or when returning to the menu pages from another point, add the command Chain to GDU.
  8. When exiting the menu pages to the next screen in the ordertaking process, put Do Template GDUTOTAL followed by Print to GDU.

Technical

The GDU requires that all commands start with an STX(2) and end with an ETX(3). Commands currently used by the templates include:

    *      ASCII:2,67,3      ;Clears the display 

    *      ASCII:2
      Wrrcc(text)      ” title=”Grin” />isplays text at row(rr) and column(cc)

      ASCII:3 

The GDU chain in the styling module will display the last eight items on the order only. Every template clears the display and then redraws it in its entirety.
Autoexec.Bat

The GDU communication parameters are 9600,N,8,1. To communicate properly the standard MODE command is required:

    MODE COM1:9600,N,8,1

Cabling

There are no status lines needed to drive the GDU. Jumpers allow the CPU to transmit data. If the GDU is disconnected, turned off, or not working, the workstation will continue to operate normally with no error message displayed.
