Thumbwheel Switch

EPROM

Blocks to be demonstrated:

Objective:

To understand how to self test Single Chip and EPROM.

Back

Procedure:

1. Turn off the power. Connect the wires as shown in next slide.

2. Turn on the power.  If the speaker beep 4 times and the Status

Display shows “1”, it means that the Single Chip and EPROM work

functionally.

3. Remove Control2 from Ground.  The Status Display will display the

value shown on Thumbwheel Switch.

4. Adjust the Thumbwheel Switch below 4095.  The Status Display will

show the current value of the Thumbwheel Switch.

5. Adjust the Thumbwheel Switch over 4095  The speaker will alarm and

the Status Display shows “0000”.

DCV Measurement (Manual)

Objective:

To understand how to use Potentiometer.

To use DC Voltage Meter to measure DC Voltage manually.

DC Power

+12V, -12V

Select / Manual

Range Button

Blocks to be demonstrated:

Potentiometer

Back

Procedure:

1. Turn off the power.

2. Connect the wires as shown in next slide.

3. Turn on the power.

4. Press Range button twice.  Select the measuring range of DCV ( -20V

~ +20V)

5. Rotate the Potentiometer.  The output voltage at VR2 will display at

Status Display section (-12V ~ +12V) .

Discussion:

When connects MANUAL to the GND,

Status Display Section acts as DC

Voltage Meter.

DCV Measurement (Chip)

Objective:

Use A/D Converter, Single Chip and Status Display to measure DC voltage

Blocks to be demonstrated:

Potentiometer

A/D Converter

Back

Procedure:

1. Turn off the power.

2. Connect the wires as shown in next slide.

3. Turn on the power.

4. Press Range button twice.  Select the measuring range of DCV ( -20V

~ +20V)

5. Rotate the Potentiometer.  The output voltage at VR2 will display at

Status Display section (0V ~ +5V) .

Discussion:

1. When connecting CHIP to the GND,

the analog signal received from A/D

Converter will send to single chip for

decoding and output to 7 segment

display.

2. When sending the analog signal to

the PC, the signal should be

converted to digital format. As the

result, this technique will be used

when connecting the main unit to the

PC. Check next exercise.

Warning!!

The max voltage input to ADC is 5V.

RS-232C

Blocks to be demonstrated:

Potentiometer

A/D Converter

Back

Procedure:

1. Turn off the power and connect the wires as shown in next slide.

2. Connects RS-232C port to PC COM port by using K&H RS-232 Cable.

3. Turn on the power and launch the KL-620 software.

4. Press the [Acquire] button.  Start to record the DC voltage.

5. Rotate the Potentiometer.  The output voltage at VR2 will display at

software panel.

Discussion:

When connecting CHIP to the GND and

CTRL pin to GND, the analog signal

received from A/D Converter will send

to PC through RS-232 interface.

Warning!!

The max voltage swing input to ADC is -5V ~ +5V.
