1. Introduction
It is a part of educational system, students using this system can transmit answers
though it to PC remotely. Then a receiving part accepts the signal form the each
student and passes it over to a PC. Finally, the PC saves the answers and reconstructs
them.
2. Remote Keypad
It has a unique ID. It can be operated in the Presentation & Test mode.
In case of Presentation Mode, once if the number key on the keypad is selected, it
transmits the unique ID and corresponding IR signal.
And regarding Test Mode, an user can store any answers in the remote keypad & the
maximum stored data will be 999 and the stored answer will be transmitted to PC
after downloading at IR USB Receiver.
2.1 General Features
There are two modes - Presentation mode and Test mode
LCD display - Question Number , Answer and so on
15 buttons (0~9, *, ? ,↓(N), ↑(Y), T/P)
LED - Lights when button is pressed while in Presentation Mode
- Lights when low battery voltage is detected
z Two batteries – CR2450 (3V) x 2ea
z Non-volatile memory (EEPROM) capable of storing up to 999 single digit
responses
2.2 LCD display

ID code is stored in a non-volatile EEPROM.
Each keypad except ↓(N), ↑(Y), T/P have unique factory programmed
System ID when the Presentation mode
2.5 Presentation mode
While in "Presentation" mode, units LCD Display is completely blank, except
when key is press and unit functions exactly like ResponseCard IR units. Any
Transmission key (0~9, * and ?) should be “echoed” for three seconds in the
Answer field of the LCD.
LCD display is blank when Normal
status
Echoed for 3 second when key is
pressed
2.5.1
Setting ID
ID of each remote can be set to a desired ID code as follows:
a) Press and hold both “*” and “6” buttons until LED is lit constantly.
b) Press the numeric key corresponding the desired ID code.
For code “000123”, ‘0’, ‘0’, ‘0’, ‘1’, ‘2’, ‘3’ serially.
c) IR remote will acknowledge by blinking LED 3 times.
2.5.2
Revert back to factory programmed ID
ID of each remote can be reverted to an original factory programmed ID code
as follows:
a) Press and hold both “*” and “1” buttons until LED turns on constantly.
b) IR remote will acknowledge by blinking LED 3 times.
2.6 Test mode
When Mode button (T/P) is pressed, unit promptly to input control number.
When 3 digits are input, unit enters "Test" mode.
2.6.1

•
Operation in Test mode
While in Test mode, no data is transferred via IR.
LCD displays “TEST” under Answer space.
LCD displays to show 001 Question and Blank Answer.
•
•
•
Student can use Up and Down Scroll buttons to change Question Number
001~999, enter and/or review answers already stored.
Student can change the wanted number by themselves through Goto function.
a) Press ‘*’, then the first digit will be blink for Question Number.
b) If press the wanted number, the next digit will be blink for Question
Number.
c) And press the wanted number, the next will be blink for Question
Number of third digit.
d) Press ‘?’. then stop to blink the digits and return to test mode.
When any answer is entered into the unit, the answer and corresponding
question number are displayed for three seconds. After three seconds the
Question number field is automatically incremented and the Answer field goes
blank.
The answer is displayed for 3 second
when the answer is pressed
After three seconds, the Question
number field is automatically incremented
•
•
Answers and corresponding Question numbers are stored in EEPROM until
deleted by user.
Students may return to Question numbers they have already answered or
skipped, and change (i.e. enter new) answers.
•
Once student has completed test, Mode button (T/P) is pressed again. Unit
displays "Leave Test Mode? (Y/N)" message. If "Y" is pressed, unit switches
from Test mode to Locked mode and displays “LOCK” under Answer space.
While in Lock mode, units Presentation capabilities are fully functional.
•
Unit may not leave Lock mode until stored answers are downloaded
and previously stored answers are deleted.
Units are aimed at IR receiver and transmission/download is initiated by
pressing the * and ? keys simultaneously.
Once Unit’s Test data is downloaded, Unit is permitted to re-enter Presentation
mode or be downloaded again.
•
