LED function
A green Status LED and a red Failsafe LED indicate the state of the TX325 transmitter by using various blink patterns. Green LED Status indicator blink patterns and Red LED Failsafe indicator blink patterns provide the blink patterns for the green Status and red Failsafe LEDs, respectively.
| Blink pattern | Indicates |
|---|---|
| At power up, blinks on and off two times. |
Normal software is running. RS-232 control interfaces enabled. Power-up initialization complete and ready to receive commands. |
| At power up, blinks on and off three times. |
Bootloader software is running. Ready to load new operating system. |
| On continuously. | Transmitter failed to start up normally after power up. Turn the transmitter off and on to reboot. |
| Blink pattern | Indicates |
|---|---|
| Blinks on and off four times per second. | A transmission is in progress. |
| Blinks on and off two times per second for 30 s. |
The post-transmit interval is in progress. The transmitter enters this state after its RF output is turned off either by a Reset command or by the normal completion of a data message transmission. The radio needs to wait 30 seconds before making another transmission to keep it from going into Failsafe mode. |
| On continuously. | TX325 is in the Failsafe mode. To clear a Failsafe mode, push the Reset button (Reset button and fail-safe LED location). A power cycle will NOT clear the Failsafe mode. |
