12: I/O Configuration

Rev 1 Nov.14
The I/O tab in ACEmanager applies to all Sierra Wireless AirLink
devices that feature I/O ports.
You can use the input/outputs on AirLink devices to generate reports
based on a threshold being crossed, a switch being opened or
closed, or the number of times a switch has changed state.
Use the Events Reporting screen to configure reports. (See
Reporting Configuration on page 197.) Use the I/O screen to view the
current state of the digital inputs, to turn the relays on and off, and to
configure the units you want used in the reports based on analog
inputs.
The number of digital input/outputs depends on the device.

AirLink ES440

The AirLink ES440:
• Has one pin (Pin 4 on the power connector) that can be
configured as a digital input/output or a relay output
• Does not support analog input

For more information, refer to the Hardware Configuration User
Guide for your AirLink device.

Digital inputs

Digital inputs monitor contact closures on a switch. This allows you to
monitor changes such as:
• When a door or latch is open or closed
• When a container is full or empty
• When a switch or valve is opened or closed
• The level of fuel in a vehicle (connected to an on/off sensor)
• When the trunk of a vehicle is opened or closed
You can use Events Reporting to generate reports and actions based
on the digital input values.
