The host computer controls the multi-passband control system of the solar telescope automatically through adjusting the crystal angle with dozens of machines in HuaiRou Solar Observing Station. The previous computer controlled several machines to adjust multi-passband system by only one serial interface. It must take much more time and its speed is quite slow, therefore this technique has fallen back. The use of the widely used USB chip CYPRESS EZ - USB to reform old serial interface is largely fast for the speed of response. The article also puts forward a method of "serial number". By this way the host computer can identify each USB equipment by its fixed serial number, no matter the inserting sequence is. PC controls the crystal angle of the multi-passband solar telescope (16 machines) by four devices. This would be a basis for other computer interfaces reforms.
