MDU 01 English Tech. Manual PDF format.

Ver. 5.00 - Rel. 29 September 2003.

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.
