• Pin 3 (On/Off)—Connect to an on/off switch
Pin 3 must be connected.
• Optional—I/O 1, I/O 2, and I/O 3
An On/Off installation may also use a sensor with an open-collector NPN or PNP
transistor. The transistor is the switch to turn the FX30 on or off, as shown in
Figure 2-17.

• Pin 2 (Ground)—Use the black wire in the DC cable to connect Pin 2 to
ground. See also Step 2—Mount and Ground the FX30 Chassis
• Pin 3 (On/Off)—Connect to the emitter pin of the transistor
Pin 3 must be connected.
• Optional—I/O 1, I/O 2, and I/O 3
Note: See Table D-1, FX30 Hardware Feature to Linux Interface Mapping,
the radio module GPIO and Linux interface mapping of pin 3, I/O 1, I/O 2, and I/O 3.
Installation with I/O Input Triggered by Standby Mode
If you have an installation where you want to use the I/O to monitor an external
device such as a motion detector or gate sensor, refer to
you can use Legato to program the I/O line to wake the gateway from ultra low
power mode for a specific length of time.
