MLRemote Network Communication
Standard MLRemote devices communicate with their MLBase using an integrated Digi XBee 900Mz radio module.
Two versions of the 900MHz XBee are offered, the standard xBee SX Module and the XBee-Pro SX which uses a
higher power output, depending on the required transmission distance.
Note – An optional 2.4GHz Digi XBee module is also available. Contact Canary Systems for more information on these
models.
The integrated XBee modules allow for the MLBase to communicate with MLRemote devices easily at a distance of
up to 15km (9 miles) in most topographies using the standard antenna. A distance of up to 100km (60 miles) may be
achieved using an optional directional antenna with excellent topography.
Server Network Communication
The MLBase is also equipped with an integrated xPico 2.4/5 GHz module used for connecting the MLBase to a
site's network. The MLBase module has a built in Ethernet port for situations where a wired network is available.
The xPico module is used to receive program updates form MLWebHardware and to send data back to the server
where MLSuite is installed.
Note - In areas where a 2.4GHz signal is not available, an MLBase can be shipped with a cellular daughter board. Contact
Canary Systems for more information on these models.
Power
A 50AHr lead-acid battery provides power. Recharging is provided through a solar panel or AC power connection.
LED Status Lights
Several status LEDs are used for reporting basic system operation. All LEDs are controlled by the microcontroller to
allow for reduced power consumption by supporting "blinking" operation. Blink modes are specified for different
reporting conditions. LED status lights are available for the following:
GREEN (POWER LED) - A flashing green light indicates the system is powered and operating. A fixed green
light displays when the system is loading.
RED (CHARGE LED) - A flashing red light indicates the battery charging current:
▪
Inactive - the current is less then 20mA
▪
Flashing (single flash) - the current is up to 150mA
▪
Fast Flashing (double flash) - the current is above 150mA
BLUE (Radio Link Active) - A flashing blue light indicates RF activity and whether the radio module is receiving
or transmitting.
YELLOW #1 (Local Area Network (LAN) Link) - A flashing yellow light indicates a valid LAN/WLAN link is
detected.
YELLOW #2 (Local Area Network (LAN) Active) - A second flashing yellow light indicates if there is any
LAN/WLAN link activity.
