The control of the steering gear generally requires a time base pulse of about 20 ms. The high level portion of the pulse is generally an angle control pulse portion in the range of 0.5 ms to 2.5 ms, with a total interval of 2 ms. Taking the 180 degree angle servo as an example, the corresponding control relationship is this:

    0.5ms————–0 degrees;

    1.0ms————45 degrees;

    1.5ms————90 degrees;

    2.0ms———–135 degrees;

    2.5ms———–180 degrees;
