(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。
