常规的加装法厂家说明书中已讲到:下面就谈一些在实际加装中常用到小经验,适用于芯片为CTV322S或CTV222S的遥控器。 1.四模拟量控制电压高低悬殊的彩电。如三菱CT—1823HD的改装。该机对比度控制电压低,其调节范围为0～4.3V,若按常规接于LM324输出侧,对比度就会过深,可将CPU⑤脚断开,如图1,加RC滤波后以CPU输出直接控制对比度。
Routine installation method The manufacturer’s instructions have been mentioned below: Here to talk about some of the actual installation to commonly used small experience for the chip CTV322S or CTV222S remote control. 1. Four analog voltage control disparity between the color TV. Such as Mitsubishi CT-1823HD modification. Contrast control of the aircraft low voltage, the adjustment range of 0 ~ 4.3V, if by conventional access to the LM324 output side, the contrast will be too deep, the CPU ⑤ feet disconnect, as shown in Figure 1, plus RC filter to the CPU output directly Control the contrast.
