these two types of devices. For any other DiSEqC devices' usage or more details, please refer to the device operation
manual or DiSEqC standards.

DiSEqC Commands Example:
MT_FE_DiSEqC_MSG msg;
msg.data_send[0] = 0xE0; /*Framing Byte*/
msg.data_send[1] = 0x10; /*Address Byte*/
msg.data_send[2] = 0x38; /*Command Byte*/
msg.data_send[3] = 0xF0 + (port - 1)*4;
/*Data Byte*/
msg.size_send = 4; /*Data size to be sent*/
msg.is_enable_receive = FALSE; /*Do not receive the reply messages*/
if(18V) msg.data_send[3] |= 0x02; /*Bit 1 set 1*/
if(22K on) msg.data_send[3] |= 0x01; /*Bit 0 set 1*/
