/* | 2.	发送DiSEqC1.2命令之前必须给LNB供电, 发送完之后恢复LNB供电状态		  | */	
/* | 3.	发送DiSEqC1.2命令之前必须保存22K状态, 发送完之后恢复				  | */	
/* | 4.	设定马达转动最东/最西端限制的步骤:									  | */	
/* |	1).	取消马达转动范围限制:						 					  | */	
/* |	2).	向东或向西转动:	东转:										      | */
/* |						西转:											  | */	
/* |	3).	转到合适位置后停止马达转动:										  | */	
/* |    4).	保存当前位置为最东/最西边限制: 东: 								  | */
