R4WRRUSB01Infrared Remote USB Receiver

< ResponseCard XL > 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 z There are two modes - Presentation mode and Test mode z LCD display - Question Number , Answer and so on z 15 buttons (0~9, *, ? ,↓(N), ↑(Y), T/P) z 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 • 4 large digits ; 3 for Question Number and one for Answer When Presentation mode When Test mode • In Test mode, a dialog display to interface with user with feedback questions such as "Lease Test Mode? (Y/N)" and “Erase Stored Data? (Y/N)” 2.3 Buttons There are 15 buttons for education XL remote keypad. 2.4 ID code There are 6,291,456 possible ID combinations available. Range: A00000 ~ FFFFFF 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 ↓(N) ↑(Y) T/P 1/A 2/B 3/C 4/D 5/E 6/F 7/G 8/H 9/I * 0/J ? 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. • To re-enter Presentation mode, “T/P” button is pressed. User is asked “Erase Stored Data? (Y/N)”. • If Y is pressed, all stored data is deleted and unit re-enters Presentation mode. • If N is pressed unit remains in LOCK mode. 2.6.2 Method for transmission/download a) Units are aimed at IR receiver b) Press the “*” and “?” keys simultaneously c) When Transmit is started, unit transmits Unit ID, Control number, Number of Answers, Answers and End String via IR. Each transmission is send from answer of first question number (001) to last answer of maximum question number that have been input recently d) A LED flash as data is transmitted and goes out seconds when complete. 2.6.3 Power save mode while in Test mode a) LCD panel is displayed to blank if there is no button activity for 5 minutes while in Test mode. b) Any key press should wake unit up and the initially pressed key, which wakes the unit up, not be utilized in anyway. c) When leaving Power Save mode, unit return to exact place and state, prior to entering Power Save Mode 2.7 Range 2.7.1 Range while in Presentation mode The nominal IR transmission distance is 13m (~ 42’) when the battery is fresh. The IR transmission distance may reduce as the battery wears out. 2.7.2 Range while in Transmission/Download …
