Airlink101 LX60 Hardware User's Manual page 25

Note: During bootup, the I/O settings remain in their default state: the internal pull-up resistor is
disabled, and output current sink switch is open. After bootup, any custom I/O settings are applied.
This may take approximately 30 seconds after the gateway is restarted or powered on.
You can use the I/O pins in conjunction with events reporting to configure the LX60 to
send a report when the state of the monitored router changes, for example when a switch
is opened or closed. For more information, refer to the ALEOS Software Configuration
User Guide (Events Reporting chapter).
Pulse Counter
Pulse counter functionality is available on Pin 4 on the power connector and on Pins 2, 3,
6, and 7 on the auxiliary I/O connector.
You can connect any of these pins to a pulse counter. The digital pulse counter is not
available in Standby mode.
