APPLICATIONS BOARD
APPS-BD |
The ABITEC APPLICATIONS BOARD (APPS-BD) contains a broad variety of applications on one product and is an ideal, economic target for demonstrating how to interface a computer to the outside world. |
|
|
A Micro-controller or Microprocessor Training system or an IBM compatible P.C. can be used to create simple programs involving the "real time" application of control and measurement devices. |
The techniques of controlling Fibre Optic Data Transmission, Keyboard entry, Digital sound production, D.C. and Stepper motors, Heaters, and Visual displays such as Traffic lights and Electronic Message boards can all be clearly demonstrated using this product.
This will involve the fundamentals of microprocessor programming, such as decision making, D/A and A/D conversion, open and closed loop control, creating delay loops, using subroutines and event counting. |

|
| INPUTS |
:: |
OPTICAL FIBRE RECEIVER |
- |
Can be linked by 1mm Fibre optic cable directly to the Optical Fibre Transmitter on the same board or to receive signals from a separate board |
:: |
8 BIT DIGITAL SWITCH BANK |
- |
Slide switches of a substantial size that can be quickly set, the position of each being immediately recognised. |
:: |
NUMERICAL KEYPAD |
- |
standard 12 key telephone layout matrix circuit. |
:: |
OPTICAL SPEED and POSITION SENSOR |
- |
a three bladed propeller mounted on the DC motor is positioned to pass between
an infrared transmitter and detector. |
:: |
TEMPERATURE SENSOR |
- |
positioned to monitor the temperature of the heater which in turn is controlled by the propeller fitted to the DC motor. |
:: |
SLIDE POTENTIOMETER |
- |
The 60mm slider moves adjacent to a 0-100% graduated scale giving the student a positional guide when using the potentiometer to vary the analog I/P voltage to the ADC. |
:: |
EXTERNAL ANALOGUE INPUT |
- |
a high impedance I/P suitablefor transducers with a range of 0-2.5 V DC. |
|
|
OUTPUTS
|
:: |
OPTICAL FIBRE TRANSMITTER |
- |
Can be linked by 1mm Fibre optic cable
directly to the Optical Fibre
receiver on the same board or to transmit signals to a
separate board. |
:: |
D.C. MOTOR |
- |
capable of speeds of up to 9000 RPM and fitted with a three bladed propeller. |
:: |
8 LARGE L.E.D.s |
- |
8mm square "Tombstones" in Red, Yellow and Green arranged in sequence to enable two sets of Traffic light and a pedestrian crossing to be simulated. |
:: |
HEATER |
- |
achieved using a 2.5W resistor, with a temperature sensor in close proximity, is positioned in the cooling air path generated by the motor propeller. |
:: |
2 DUAL SEVEN SEGMENT DISPLAYS |
- |
Bright red 0.56" high characters can be put to many uses including monitoring the temperature of the on board heater or the speed of the DC motor. |
:: |
ANALOGUE OUTPUT |
- |
digitally generated, an output of 0-2.5V can be achieved. |
:: |
SPEAKER |
- |
with a frequency range of 1.3 to 8KHz it can be connected to digital line or to the digital to analog converter allowing the students program their own tunes. |
|
| The
STEPPER MOTOR MODULE (STEP-OPT) is an optional accessory
for the Applications board. Ready to connect to P3 of
the applications board, the MD35 style stepper motor is
supplied mounted in an acrylic frame and fitted with a
dial and pointer. The option is supplied with a driver
I/C to plug into socket IC7 of the control circuitry built
into the Applications board where LEDs indicate the status
of the drive to the Stepper motor. |
| The
LIQUID CRYSTAL DISPLAY MODULE (LCDM-OPT) is also an optional
accessory for the Applications board. Ready to connect
to P4 of the applications board, the 2 line by 20 digit
LCD Module is supplied mounted in an acrylic frame for
ease of handling. This option is invaluable for demonstrating
the display of messages, warnings or instructions, as
used on small instruments or on large public information
boards such as those found at rail stations, airports,
etc. The techniques for rolling, flashing and alternating
messages can be shown. |
Applications
boards are supplied with a Storage Case , User Manual
and Power Supply Unit as standard. |
Experiment
manuals are available for Motorola 68000 and Zilog Z80
microprocessors and for the PIC micro-controllers. Manuals
will also shortly be available for 8086, 8051 and 68HC11.
The applications board is fully compatible with the Abitec
target systems Z80-DATS, PIC-DATS, PIC877-TB, KAYCOMP
II, PL-DATS and MC11-DATS. Interface cables can be custom
made to suit other manufacturers products. |
