（一）专业型和工程型卫星数字电视接收机的操作方法
专业型和工程型卫星数字电视接收机一般不配备遥控器，主要应用于有线电视台前端、集体接收用户前端。主要控制操作方式：通过RS-232串口或LAN接口进行遥控操作，通过接收机面板的按键进行手动操作。
注意：对于C频段节目，卫星接收机的接收本振频率需要设为5150MHz; 对于Ku频段节目，卫星接收机的接收本振频率需要设为11300MHz。
通过RS-232串口或LAN接口遥控配置参数（必须由厂家或厂家授权的专业技术人员操作）
将高频头（或经过功分器）输出的卫星电视信号送入接收机。
在控制计算机内设置好预接收节目信号的参数后，通过卫星接收机的控制接口写入接收机。
