DESCRIPTION
The Message Display Intelligent (MDI) unit is a simple-to-use, yet versatile
and powerful alphanumeric message center. The broad flexibility and
functionality of the MDI make it particularly adaptable to a wide variety of
applications, including:
Display and Monitoring of Measured Values
Indication of Warning, Error, and Alarm Conditions
Monitoring of Manufacturing Processes
Display of Machine Start-Up and Operation Procedures
The MDI is capable of storing and displaying up to 256 separate messages.
A message can contain up to 250 characters of text and can display any of the
153 customizable characters, including the standard 96 character ASCII set.
Individual lines of the message text can be programmed to scroll in a block or
character fashion. Individual characters, blocks, and lines of text can be
programmed to blink.
The MDI can assemble and transmit message text to one or more Message
Display Slave (MDS) units for remote display of messages. For interfacing with
serial printers and ASCII terminals, the message text can be assembled and
transmitted in any format the user desires. In this case, the appropriate lower
ASCII control characters can be inserted in the message text where necessary.

Messages can also display the Current Time and Date and any of the MDI's
sixteen Elapsed Timer values. A message can also collect and display multiple
Embedded Data items.
Messages can be requested via the MDI's Serial and Parallel ports, which the
user can configure to meet the needs of most applications. The Parallel Port can
also be configured to issue Automatic Message Requests based on changing
port values.
The MDI contains functions for requesting messages on a Periodic basis, and
for processing requests based on Elapsed Time and Embedded Data values, as
well as for executing Chained and Linked message lists.
Any programmed message can be designated for automatic request on Unit
Power-Up and Reset. A separate message can be designated for display when
the MDI's Display is blank.
RLC offers IBM
MDI. The Message Display User software (SFMD), with its easy-to-use menus,
extensive prompts, on-line Help functions, message simulator, and terminal
emulator, greatly assists the user in fitting the MDI to the application at hand.
The user can easily create and save multiple Configuration, Character, and
Message files with the SFMD software. Extensive file handling features are
included, such as uploading, downloading, and printing of files. Message
simulation and terminal emulation functions also come with the software.
Note: Recommended minimum clearance (behind the panel) for
mounting clip installation is 2.1" (53.3) H x 5.5" (140) W.
