Watchdog and Outputs – This screen allows you to setup the watchdog timeout and the two physical outputs on the Receiver. The Watchdog is in seconds and is the time that the receiver looks for signal loss from the Protothrottle. If set to zero, there is no timeout. Otherwise, if set to non-zero, it will wait that many seconds, then decelerate the outputs, both DCC and ESC to zero, stopping the locomotive. The two outputs can be set to respond to DCC function codes and also have the option of being ON when the actual output is low. Generally relay boards and other outputs are energized by taking a logic level low, but you can use this to set it to active low or high depending on your needs.
