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 2-10 .
You can configure the I/O line to wake the router up for a configured length of time, and
use Low voltage disconnect to put the router in Standby mode if the voltage falls below a
configured value.
Figure 2-10: 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 recom-
mends 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 RV55 Router Chassis on page 19.
• Pin 3 (Ignition Sense)—Connected to power
• Pin 4 (GPIO)—Use the green wire for I/O configurations. See I/O Configuration .
I/O Configuration
You can use the Pin 4 (GPIO) green wire as:
· A pulse counter
(See
Table 2-5 on page 30 and Figure 2-11 on page 30.)
· A digital input
(See
Table 2-5 on page 30 and Figure 2-12 on page 31.)
· A high side pull-up/dry contact switch input
(See
Table 2-7 on page 32 and Figure 2-13 on page 32.)
· An analog input
(See
Table 2-8 on page 33 and Figure 2-14 on page 33.)
· A low side current sink
(See
Table 2-9 on page 34 and Figure 2-16 on page 34.)
· A digital output/open drain
(See
Table 2-10 on page 35 and Figure 2-17 on page 35.)
For more information, refer to the ALEOS Software Configuration User Guide.
Note: You can configure the GPIO Pin 4 in ACEmanager or ALMS to trigger standby mode, to sink
current, or to pull up the voltage. If you are using the I/O line to trigger standby mode, you cannot
configure it to sink current or pull up the voltage. Likewise, if you are using the I/O line to either sink
current or pull up the voltage, you cannot use it to trigger standby mode.
