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.
