MDU 01 is a card capable
to solve all the operator interface problems, when the customer
wants to develop himself the panel front size (display, keyboard,
etc.). It is specifically designed for industrial use and for
direct mounting on automatic machinery control box.
The MDU 01 includes all the electronics of a video terminals
and it is suitable to be the direct interface between operator
and machinery in any of the control or comand operations which
could be necessary during running or diagnostic of the same.
MDU 01 can directly drive alphanumeric Fluorescent or LCD
Displays, with or without LEDs plane backlite in
the 20 characters for 2, 4 lines size or
40 characters for 1, 2, 4 lines size.
Moreover the MDU 01 has an interface for a matrix keyboard
provided of 7x4 = 28 keys, with software configurable codes,
and an interface for 22 status LEDs that can be
turned on and off through proper serial commands.
The basic version of MDU 01 can be expanded utilizing
the various options available, as: serial EEPROM, up to
4 Kbyte capacity for message saving; Real Time Clock
with 256 Bytes of user RAM, backed by Lithium
battery; one relay managed by serial line; magnetic badge card
acquisition, both with manual and motorized readers; many communication
protocols; etc.
A set of connectors allow card connection to the external electronics
in a fast and comfortable manner; so the customer can develop
his specific operator interface with no additional costs.
The MDU 01 is able to execute an entire range of display
commands, including Clear Screen, Position cursor, EEPROM
reading or writing, LEDs Blinking, etc., compatible with
the ADDS ViewPoint video terminal.
Features of MDU 01 are below described:
- - Dimension: 150 x 100 x 40 mm (W x H x D) with mounting
hole on the card corner.
- - Optional plastic container for DIN 46277-1 and DIN 46277-3
rails.
- - Interface for matrix keyboard with 7x4 = 28 Keys,
on low profile connector.
- - Complete keys codes configuration through software, from
the user.
- - Direct interface for 22 status LEDs, provided
of Blinking attribute, on
low profile connector.
- - Interface for intelligent alphanumeric display, on low
profile connector, available in the following models (it must
be specified during order phase):
- LCD Display, backlite
or not, with 2, 4 lines for 20 characters
- Fluorescent Display with
2, 4 lines for 20 characters
- LCD Display, backlite
or not, with 1, 2, 4 lines for 40 characters
- Fluorescent Display with
1, 2, 4 lines for 40 characters
- - Buzzer programmable as BELL or with keyclick
function.
- - EEPROM up to 4 Kbyte, used for permanent
storage of Set-Up, Messages, Key Codes,
etc.
- - Memorization on EEPROM and visualization of more
than 100 different messages, even with auto Sliding
Mode.
- - 1A Relay with changeover contacts, serially controlled.
- - Interface for Magnetic Badge
Card Reader on 1, 2, 3 track, motorized or manual.
- - RTC with 256 Bytes user accessible RAM
backed by Lithium battery.
- - RS 232, RS 422, RS 485 or Current Loop serial
line.
- - Communication selectable between point to point and Master
Slave mode.
- - Local set up for communication parameters (Baud
Rate, Stop bits, Keyclick, etc.).
- - Internal power supply capable of driving small external
loads.
- - DC or AC power supply from 5 Vdc to 24 Vac.
