Abstract
As society progresses, the intellectualization is constantly melting into our life and production. We no longer personally use hand to control the operation of equipment, instead of which, we apply remote control so as to meet our requirement. In the context of this produces a large number of intelligent products, of course, a similar study on this can been seen everywhere. VC as a mainstream development platform, has been well received by programming enthusiasts, but this article is to be set in the VC + + environment to achieve control of head rotation. By connecting PC with the head through the RS-485 and using PELCO-P protocol, with serial communication control MSComm, in VC + +, programming, we can make PC control the rotation of the head. This article discusses the use of PC-controlled by the HZ-01ET PTZ decoder.
