.SH DESCRIPTION
.B longmynd
Interfaces to the Minitiouner hardware to search for and demodulate a DVB-S or DVB-S2 stream. This stream can be output either to a local FIFO (using the default or -t option) or to an IP address/port via UDP.

The Main TS stream is the one coming out of the Primary FTDI Board.
.SH OPTIONS
.TP
.BR \-u " " \fIUSB_BUS\fR " " \fIUSB_DEVICE\fR
Sets the USB Bus and USB Device Number of the required Minitiouner in a multi device system.
Default uses the first detected Minitiouner.
.TP
.BR \-i " " \fIIP_ADDR\fR " " \fIPORT\fR
If UDP output is required (instead of the default FIFO output), this option sets the IP Address and Port to send the Main TS Stream to.
Default is to use a FIFO for Main TS Stream.
.TP
.BR \-I " " \fIIP_ADDR\fR " " \fIPORT\fR
If UDP output is required (instead of the default FIFO output), this option sets the IP Address and Port to send the Main Status Stream to.
Default is to use a FIFO for Main Status Stream.
.TP
.BR \-t " " \fITS_FIFO\fR
Sets the name of the Main TS Stream output FIFO.
Default is "./longmynd_main_ts".
.TP
.BR \-s " " \fISTATUS_FIFO\fR
Sets the name of the Status output FIFO.
Default is "./longmynd_main_status".
.TP
.BR \-w
If selected, this option swaps over the RF input so that the Main TS Stream is fed from the BOTTOM F-Type of the NIM.
Default uses the TOP RF input for the Main TS stream.
.TP
.BR \-b
If selected, this option enables a tone audio output that will be present when DVB-S2 is being demodulated, and will increase in pitch for an increase in MER, to aid pointing.
By default this option is disabled.
.TP
.BR \-p " " \fIh\fR " "| " "\-p " " \fIv\fR
Controls and enables the LNB supply voltage output when an RT5047A LNB Voltage Regulator is fitted.
"-p v" will set 13V output (Vertical Polarisation), "-p h" will set 18V output (Horizontal Polarisation).
By default the RT5047A output is disabled.
.TP
.BR \fIMAIN_FREQ\fR
specifies the starting frequency (in KHz) of the Main TS Stream search algorithm".
.TP
.BR \fIMAIN_SR\fR
specifies the starting Symbol Rate (in KSPS) of the Main TS Stream search algorithm".

.SH EXAMPLES
.TP
longmynd 2000 2000
will find the first available Minitiouner, search for a 2MHz TS Stream at 2MSPS on the TOP RF input, output the TS to a FIFO called "longmynd_main_ts" and the status to a FIFO called "longmynd_main_status".
.TP
longmynd -w 2000 2000
As above but uses the BOTTOM RF input.
.TP
longmynd -u 1 4 2000 2000
As above but will attempt to find a minitiouner at usb device 4 on usb bus 1.
.TP
longmynd -i 192.168.1.1 87 2000 2000
As above but any TS output will be to IP address 192.168.1.1 on port 87
