Fixed Installation with I/O Input Triggered by Standby
Mode
If you have a fixed installation where you want to use the I/O to monitor an
external device such as a motion detector, remote solar panel, or a remote
camera, refer to
Figure 3-8 . You can configure the I/O line to wake the gateway up
for a configured length of time, and use low voltage disconnect to put the gateway
in Standby mode if the voltage falls below a configured value.
Figure 3-8: Fixed Installation with I/O
• Pin 1 (Power) — Use the red wire in the DC cable to connect Pin 1 to the
power source. Include a 4.0 A fast-acting fuse in the input power line. Sierra
Wireless recommends using a continuous (unswitched) DC power source.
• Pin 2 (Ground) — Use the black wire in the DC cable to connect Pin 2 to
ground. See also
Grounding the RV50 Series Gateway Chassis on page 30.
• Pin 3 (Ignition Sense) — Connected to power
• Pin 4 (GPIO) — Use the green wire for I /O configurations. See I / O Configu-
