ON
OFF
The Wi-Fi hotspot is turned on for 10 minutes:
•
at boot up
•
when the station is connected to, whether via
USB, over the modem, or over Wi-Fi
•
after an SMS is received
•
after a LISTEN command.
The Wi-Fi hotspot turns on for one hour when:
•
The wakeup button is pressed
•
The station goes into alarm

Log Daily Values
The station can log diagnostic information at 23:59:59 each day. That information consists of
current battery voltage, current temperature, and telemetry accounting, such as the number of
transmissions made and the number of bytes transmitted.
To prevent this data from being logged, disable the
Log Daily Values
setting as shown below. The
data will only be downloaded if the
Include Events
option is selected during the download.

Digital Output
XLink includes one digital output labeled DOUT 1.
The digital output is DOUT#1 (Output1). The digital output is an open collector type output. This
provides direct interface to many products. The open collector output sinks 100mA (rated at
>400mA) on a continuous basis.
It is expected that a pull-up resistor will be connected to the Prot+12V or other supply. The value
of the pull-up may be determined by the impedance of the connected load. A10 kOhm resistor
may be used as a default.
With a pull-up
resistor connected
When the output is
turned on
, the output sinks current from all attached devices.
When the output is
turned off
, the output is pulled up to the supplying voltage.
The digital output may be activated via several means.
Manually via command line. A command may be sent via LinkComm over USB, via an
SMS, via an Iridium message, or via any other means of connecting to the station.
Alarms: any sensor going into alarm may trigger the digital output.
Equations: any measurement setup with the Output function in an equation may pulse
the digital output for a specified amount of time. Please see the
section for details.
The system can automatically activate the output based on alarms. The setting
Output1 Control
dictates whether alarm activity triggers the output.
