Users Manual

Users guide This product use 2.4G radio frequency technology, applied for polling, voting, training, education, quiz... etc. One complete system includes software and hardware. Hardware includes receiver, keypads and cable. Receiver: Dimension(mm):137×137×50, half ball Weight: 0.5 kg Working temperature:0-40 Working relative humidity:0-90% Working Power consumption: 5W Receiving angel and distance for receiving: 360degree. Function: connect to PC, receiving the signals from the keypads Functions of the receiver parts: 1. Power indicator light (red): power on, light on; power off, light off; 2. Communication indicator light (yellow): when the receiver gets the order from the PC, light on; 3. Status indicator light (blue): when the receiver is activated, light on. 4. Connection port: used for connect cable. 5. JP1 is the port for RJ-45 standard network card, use standard cable to connect to the USB port of PC. U2-U5 are WM2500LP(RF CHIPSET:CC2500)2.4G radio frequency mould, they are used for transmit and receive radio signals from the keypads.SN75179 is difference driver receiver and transmit IC. U7 is 24c serial memorizer, which connected to CUP P89LV51RD2BN via data timer cable. 24.576M Crystal oscillator X1 support the timer signal for CPU P89LV51RD2BN.CPU P89LV51RD2BN controls the working mode of every mould, operating the orders from the computer, and transmits or receives via moulds. P89LV51RD2BN send the signals which have been disposed to the computer. The receiver only one working mode is 4 modules transmit and receive simultaneously. these 4 RF modules and 4 antennas own the exactly same specification and RF parameters. Keypads 1 Specification Dimension: 5.3cm*11.6cm*1.5cm Transmitter angle: 360 degree Batteries: 2 AAA ordinary batteries or alkalescence batteries Function: voting or answering, sending signals to receiver 2. Functions of the keypads’ parts: 2.1LCD display area (as pictures below) 2.1.1 Keypads ID display, from 0001 to 9999 2.1.2 Capital / lowercase input indicator 2.1.3status indicate: “ ”,inputting or editing, “--”Stop answering, “>>”sending signals, “OK”proceedings (sending signals) successfully, “ ” proceedings (sending signals) failed, “”no connection with the receiver, “ ”Searching the signal of the receiver 2.1.4 Working mode indicator 2.1.5power volume indicator 2.2Buttons area (details and name of the button may be different printed for different mould) Includes function button, input button and combination button 2.2.1 Function buttons Ok: confirm sending or handling C: clear signals or cancel < ,> :left, right, up, down, forward, downward Power button: power on/ off, capital/lowercase input Input buttons: 1-10, A-I, symbol ’ and : Agree, objective and abstain Fn combination button Cable For getting power from PC; For data communication with receiver and PC One port is RJ45, another port is USB port. Test method: 1. Connect the cable to the PC, the system will install USB driver automatically; 2. Open the test software: “ WindowsApplication1.exe”, as below: 3. Press the red circled button of 1 and 2 by order, the system will prompt the word “ok”, confirm it, then the green light of the receiver will flashing. 4. After pressing the power key on the keypads, it will search the signals of the receiver automatically. Press the buttons one by one, and you will find the result of the receiver got at the red circle 3.
