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.
