\section sConfigIO I/O Configuration
|
|
|
|
I/O configuration panel as seen above allows the user to select one of the IO
|
|
interfaces. Each of the two interface options are used for different
|
|
purpose(s). ARQ is selected when the user requires the use of the
|
|
FLDIGI suite of programs (FLARQ, FLMSG, FLAMP, etc). The KISS interface
|
|
is used with Ax25/ARQ networking software. With the this interconnectivity
|
|
multiple host programs are available to leverage this option. See
|
|
\ref kiss_host_prgs_page "KISS Host Program(s) and FLDIGI"
|
|
|
|
\par Note:
|
|
Any changes to the IP Address and/or port numbers requires FLDIGI restart.

|
|
To select ARQ I/O, mouse click on the [ ] Enable ARQ check box. If the
|
|
checkbox is grayed out, this indicated the panel is locked. Deselect the
|
|
[ ] Lock checkbox to gain access.
|
|
|
|
The ARQ section of the configuration panel allow the user to set the
|
|
IP address and port number. Pressing the [Default] button set the fields
|
|
to their startup values. In order for communications to occur both FLDIGI
|
|
and the FLDIGI suite of program must be assign the same IP address and port
|
|
number if the programs are used on the same computer. If the program are
|
|
running on different machines then the IP Address must be set accordingly
|
|
while maintaining the same port number. The IP Address entered is the
|
|
destination Address for the recipiente program/host computer.

|

To select KISS I/O, mouse click on the [ ] Enable KISS check box.
|
|
|
|
Setting and configuring IP address and ports numbers are described in the ARQ
|
|
section.
|
|
|
|
\subsection ssAx25Decode Ax25 Decoding
|
|
|
|
If the data received is using Ax25 protocol enabling this option translates
|
|
the protocol into human readable form. Only available when KISS I/O selected.
|
|
|
|
\par NOTE:
|
|
When actived, only valid ax25 data will be displayed to the receive
|
|
panel. No un-squelched random characters will be seen.
|
|
|
|
\subsection ssKISSCsma KISS I/O CSMA
|
|
|
|
Selecting this option enables Carrier Sense Multiple Access. Basically in
|
|
conjunction with KPSQL it monitors for busy signals. When the frequency is
|
|
clear a small variable delay is initiated preventing the transmitter from
|
|
transmitting. This variance allows other CSMA stations time to monitor
|
|
the frequency in an attempt to prevent/limit packet collisions. Only available
|
|
when KISS I/O selected.
|
|
|
|
\subsection ssKISS KISS over IP
|
|
|
|
FLDIGI supports KISS data tranfers over two types of IP communications.
|
|
UDP (connectionles) and TCP (connection). Each method have is avantages
|
|
and disavantages. If you wish to know more about the differences performing
|
|
a search on the internet using key words:
|
|
|
|
"TCP/IP UDP/IP"
|
|
|
|
If you are a programmer a good source and free documentation on the subject
|
|
can be found by performing a search on these keywords:
|
|
|
|
"Beej's Guide to Network Programming"
|
|
|
|
\subsubsection ssUDPIP Connectionless UDP/IP [UDP]
|
|
|
|
Selecting UDP/IP envoks a connectionless communications path. Host software
|
|
must support UDP/IP data transfers in order to use this option.
|
|
|
|
\subsubsection ssDualPort Dual Port [DP]
|
|
|
|
Used with UDP/IP communications and does not functions with TCP/IP
|
|
connections.
|
|
|
|
Since the data exchange protocol is based on UDP/IP (connectionless) a
|
|
loopback issue can arise if the two programs are hosted on the same machine.
|
|
By allowing more then one port number the loopback condition can be avoided.
|
|
Host programs must support dual port for proper communications.
|
|
|
|
\subsubsection ssTCPIP Connection TCP/IP [TCP]
|
|
|
|
TCP connections are far more reliable then UDP since the protocol confirms data
|
|
transfers between programs. UDP communications on the same machine is
|
|
generally a non issue though. It's normally an issues when distance and
|
|
congestion comes into play as packet might timeout in the transfer process.
|
|
TCP/IP can resend the data where UDP doesn't.
|
|
|
|
Select TCP/IP if the host program supports it.
|
|
|
|
\subsubsection ssLISTEN_BIND Listen/Bind
|
|
|
|
When selected (checked) with TCP/IP the interface will wait/listen for TCP/IP
|
|
connections from the host program. If unchecked the user will press the start
|
|
button and FLDIGI will attempt to connect to the host program multiple time
|
|
over a ten second period.
|
|
|
|
If the connection fails the user should ensure the FLDIGI/host program is
|
|
running and configured correctly.
|
|
|
|
The Binding is a operating system process for a given IP address and port
|
|
number. The binding of an address/port number can only occur once on the same
|
|
machine no matter how many programs use the same address and port number. If
|
|
you are getting errors as a results of binding it's possible another program
|
|
on the same machine has bound the address/port number already. Unchecking this
|
|
option may help in this circumstance. Listen/Bind is required if you want
|
|
FLDIGI to wait for connections.
|
|
|
|
To start the Listening state pressing the start button is required. In the
|
|
event the host programs disconnects FLDIGI will return to Listen state unless
|
|
the user selects the Stop button. The Start and Stop button is the same button
|
|
that is renamed depending the connection state.
|
|
|
|
\subsubsection ssAutoConnect Auto Connect [AC]
|
|
|
|
Auto connect is used to connect to the host program on start up. Configure
|
|
KISS interface as needed then enable (check) the [x] AC option. Press the
|
|
[Save] button at the botton of the configuration panel in order for it to
|
|
take effect on the next restart. This is a useful option in the event of
|
|
power failures.
|
|
|
|
\subsubsection ssInhibit7bit Inhibit 7bit Modem
|
|
|
|
Selecting this option will disable the warning message reported by FLDIGI
|
|
in the event there is a change to a modem type that is not KISS IO compatible.
|
|
The invalid modem will be ignored and FLDIGI will remain in the current valid
|
|
modem. Deselecting this option allows the operator to approve the modem
|
|
change.
|
|
|
|
This is an option that should be disabled when FLDIGI is used in an automated
|
|
state as FLDIGI will wait indefinitely for a response from the operator.
|
|
|
|
\subsubsection ssBusyChannel Busy Channel
|
|
|
|
Busy Channel when enabled and with the properly set threshold of the KPSQL
|
|
squelch. Frequencies that are intermittently present within the bandwidth of
|
|
the modem will inhibit the transmitter for the specified duration. This is a
|
|
useful feature to prevent your station from capitalizing the frequency,
|
|
allowing casual users to continue without interruptions from "BBS/Email"
|
|
type operation.
|
|
|
|
To prevent your station from transmitting between the grap of the RSID and
|
|
the data stream. Enable Busy Channel with a 1~2 second inhibit period.
|
|
|
|
\subsubsection ssKpsqlAttenuation KPSQL Attenuation.
|
|
|
|
Reduces the sensitivity of the KPSQL squelch. Useful when a direct audio
|
|
card to audio card connection.
|
|
|
|
KPSQL monitors for differences in the signal strength within the bandpass
|
|
of the modem. Making it tolerant to AGC variations from the radio.
|
|
|
|
\subsection ssModemSelection Modem Selection Kiss I/O
|
|
|
|
Use of the KISS I/O places a limit on the number of available modems. These
|
|
modems support 8 bit transfers. The slowest of these modems have been omitted
|
|
and generally comprise of the BPSK, 8PSK, MFSK, THOR, Contestia, Olivia and
|
|
MT63 at various baud rates. Any attempt to select a modem not supported FLDIGI
|
|
will ignore the request. If you are unsure, open the event log under the Help
|
|
menu and note a message indicating that particular modem is not supported.
|
|
|
|
See \ref ssInhibit7bit to change the behaviour of this modem check.
