5 Operation

5.1 LED Indicators

The iRIS has several LED indicators. The main status LED is visible from the outside of the enclosure on both models, where as the eight diagnostic LEDs are internal.

5.1.1 Status LED

The status LED is a tri-colour device that is used to indicate the unit status. The iRIS 220 has no LCD, this indicator is important as it is the only means of determining the iRIS status.

NOTE: The status LED is visible through a small hole on the antenna end plate on the iRIS 220 or through the front of the enclosure on the iRIS 320.

Status		LED Indication
Idle, low signal strength		Flashes red once every three seconds
Idle, adequate signal strength		Flashes green once every three seconds
Connecting to network		Flashes blue every half a second
Connected to network		Flashes blue once every three seconds
Failed to connect		Flashes red every half a second
Data packet sent or received		Cycles once rapidly through all three colours

5.1.2 Diagnostic LEDs

The iRIS has eight internal LED indicators that are useful for diagnostic purposes. Please note that these indicators are only active in certain power management modes (see the features Section 2.8.4 for details on power management). Also be aware that the functions of some of these LEDS are different on the earlier V1.1 PCB version. See Appendix 13.4 for details.

NOTE: The diagnostic LEDs are only visible if the PCB (printed circuit board) is exposed. For the iRIS 220, the electronic assembly must be removed from the case. For the iRIS 320, the front of the case must be opened.

232 RX	Flashes green when data is received from the RS232 port.
232 TX	Flashes green when data is transmitted out the RS232 port.
Modem RX/TX	Flashes green when there is receive or transmit activity with the wireless modem.
SDI-12 TX	Flashes green when a SDI-12 message is transmitted.
DIGIN #1	Illuminated orange when Digital Input #1 is active (pulled down to 0V).
DIGIN #2	Illuminated orange when Digital Input #2 is active (pulled down to 0V).
DIGOUT #1	Illuminated orange when Digital Output #1 is active (delivering 12V).
