Description
Red Main power supply for device
Note: If you want to turn the LX40 on/off using a control line, Sierra
Wireless strongly recommends that you connect the On/Off control line to
Pin 3 and apply continuous power on Pin 1.
Main device ground
For installations where the LX40 is to be turned on/off, use the white wire
connected to Pin 3 in the DC cable. The LX40 is off when this pin is either
open-circuit or grounded, and on when this pin is connected to power. The
LX40 should not be turned off by simply disconnecting the power.
Pin 3 can be connected to an external switch.
Note: If you do not connect pin 3 to a switch, you MUST connect it to the
positive terminal of your power supply or battery. If you are using a Sierra
Wireless AC adapter, the connection is inside the cable.
Note: When the LX40 is using PoE, On/Off control is ignored.
User configurable digital input/output or analog voltage sensing input.
Connect to switch, relay or external device. For more information, see
