JY- 238T circuit of description 1、When battery(or adapter) are inserted properly ,Turn on power switch (SW2) in ON position, Led11 of the power indicator lights up green. （if low power, Led11 of the power indicator lights up orange） 2、Channel setting: By pressing button (sw1), 4 channel of A/B/C/D can be selected, and one led of LED1、LED2、LED3、LED4 lights up green,It indicates this channel being set. 3、Signal source selection: 1)、 When switch (SW3) is in “1” position, VIDEO signal only from camera1, AUDIO signal only from mic phone. 2)、 When switch (SW3) is in “3” position, external VIDEO& AUDIO signal only external . 3)、When switch (SW3) is in “2” position, Transmitting by VOX.. Only having no voice, external VIDEO& AUDIO signal external can be transmitted: otherwise VIDEO signal from camer1 and AUDIO signal from micphone can be transmitted. 4、AUDIO signal modulation: 1) AUDIO signal from microphone amplified by IC2D or external AUDIO from jack2 can be send into sub-carrier oscillator of 6.0MHZ , 2) the sub-carrier of 6.0Mhz send into VCO and modulated. 5、VIDEO signal modulation: 1）VIDEO signal from camera1 or external jack2 sent into VCO and modulated 6、VCO oscillator circuit : frequency of VCO selection by pressing SW1, MCU send data of channel into PLL synthesizer (IC5),at the same time this data will be save by IC6(AT24C02) and then PLL systhesizer (IC5) send signal to VCO, VCO can generate 4 kinds of RF signal (2.411G/2.433G/2.453G/2.473G). 7、RF AMP circuit : RF signal of VCO is amplified by Q25 and Q26, and then transmission out by ANT. 8、Power supply and low power indicate: 1) IC3 regulate 4V voltage, when battery voltage is low , LED11 lights up orange. 9、Infrared night-led control；In darkness , value of R76 (CDS) enlarge , Voltage of pin 1 of CAMERA1 became low , the LED of infrared in CAMERA1 light up. In daylight value of R76 (CDS) reduce , Voltage of pin 1 of CAMERA1 became high , the LED of infrared in CAMERA1 light out .
