NAME

       ModuleTxFan.conf - Configuration file for the SvxLink server Transmitter Fan module

DESCRIPTION

       svxlink  is  a  general  purpose  voice  service  system  for ham radio use. This man-page
       describe the SvxLink server configuration for the TxFan module.

       The TxFan module is used to control auxiliary fans that are triggered by a PTT GPIO event.

CONFIGURATION VARIABLES

       There are a couple of configuration  variables  that  are  common  to  all  modules.   The
       documentation for these can be found in the svxlink.conf(5) manual page.

       Here  is  the  description of all module specific configuration variables that the SvxLink
       TxFan module understands.

   ModuleTxFan
       MODE   The MODE variable has 2  acceptable  values  "COUNT_DOWN"  and  "FOLLOW_PTT".   The
              COUNT_DOWN  starts  at  the value set in DELAY variable, and counts down by 1 every
              second until zero is reached. At the start of the count down, the FAN_GPIO pin will
              be  set  to  logic  high.  When the timer reaches zero, the FAN_GPIO will be set to
              logic low.  The FOLLOW_PTT  mode  will  Activate  the  FAN_GPIO  pin  when  PTT  is
              activated  (accurate  to 1 second) and will deactivate the FAN_GPIO pin when PTT is
              deactivated (accurate to 1 second).

       DELAY  Number of seconds to count down after last PTT gpio is deactivated.

       PATH_PTT_#
              The absolute path to the value file that controls the PTT pin for a given  channel.
              By default the module supports 2 PTT signals, but can easily be expanded to support
              additional channels.  Be certain to include these  pins  in  the  svxlink_gpio.conf
              file.

       FAN_GPIO
              The  absolute path to the value file that controls the FAN gpio pin.  Be certain to
              include these pins in the svxlink_gpio.conf file.

       FILES

       /etc/svxlink/svxlink.conf (or deprecated /etc/svxlink.conf)
              The system wide configuration file.

       ~/.svxlink/svxlink.conf
              Per user configuration file.

       /etc/svxlink/svxlink.d/ModuleTxFan.conf
              Global  modularized  configuration  file.  Depends  on  the  CFG_DIR  configuration
              variable setting.

       ~/.svxlink/svxlink.d/ModuleTxFan.conf
              Per  user  modularized  configuration  file.  Depends  on the CFG_DIR configuration
              variable setting.
