LED Indicators
| Status | blinks green during normal operation* |
| Busy | blinks yellow while receiving data |
| Transmit | blinks red while transmitting data |
| Error | lit red in mirror mode when communication is lost |
| IO1-IO8 |
Output: lit green while IO-n output is on** (pulled to ground) Input: lit green while IO-n input is on (pulled to ground) |
* Output will be solid-on during firmware updates.
** Output will blink green rapidly in failsafe mode.
Reset Button
The RIO-16D has one external switch. Pushing the reset button will quickly reset the device. Holding the reset button for 15 seconds or more will reset the serial mode to 57.6k baud and no parity.
The reset button is disabled during firmware updates to protect the unit.
