4.0 Brief Description
The text display is a on screen display for durable text insertion inclusive date and time
respectively to insert protocol data of the interface.
The following diagram shows an overview of the parameters that can be configured by
PS/2 keyboard and/or PC program:
All functions to edit the on screen display are configurable by customary PS/2 keyboard.
For generating an on screen text with time and date display you need no PC.
The meaning and configuration of the parameter describes chapter 5.
The general parameters of the interface control are easy to configure by the keyboard.
Only the modification and positioning of data fields can be controlled by PC program:
The PC setup interface allows the selection of created protocols from a list and a
comfortable setting of all parameters:

4.0 Brief Description - 7 -
Operating Instructions Text Display
Using a PC mouse all data fields of the protocol can be placed and moved on a 11x28
raster display.
On the raster you can create special texts to describe the positioned data fields.
All parameters and their operating are written in chapter 6.
Having programmed all parameters, these are transferred from the PC to the Text
Display. The unit now operates with the new parameters independently from the PC.
The setup data can also be stored on hard disk/diskette. Thus it is possible to transfer
standardized settings without great effort to several text displays.
In case of failure, the service engineer can determine whether the setup has been
changed by unauthorized persons and he can directly reestablish the original
configuration.
The TD uses state-of-the-art Flash technology:
Upgrading the operating software (firmware) can be performed without opening the
equipment, upgrades can be loaded via PC or laptop via the RS232 interface.
