Configure AC-powered Sensors using Discovery and Auto-Configuration
Discovery and Auto-Configuration is the preferred method for configuring AC-powered sensor
devices. During Discovery and Auto-Configuration, you connect the sensor device to the network.
The MAC address of the sensor device is transferred to the AMP, and the AMP downloads the
Default Profile as the information by which the device operates as part of the network. If the SNS
AMP has been installed and you have a network connection available on the same subnet that the
AMP is on, you can use Discovery and Auto-Configuration to configure AC-powered sensors.
Note:
Discovery and Auto-Configuration assumes that sensor devices connect to the
network using DHCP. After sensor devices are recognized on the AMP, you can
edit the network settings for each sensor device to assign it a static IP address. If
DHCP is not an option, configure sensors using Browser-based Configuration and
add the sensor device on the AMP with a static IP address before configuring it.
Otherwise, when the sensor checks in after being configured, the AMP will see it
as an "unknown" new sensor and will use the default profile to configure it, which
will wipe out the static IP address configured in the sensor. See the SNS
Temperature and Humidity Sensors User Guide for information on editing a
sensor device.
Guidelines
Before you begin be sure that the following items are available:
•
Default Profile configured for your network on the AMP. See Edit Default Sensor Profiles on
page 25.
•
A network connection on the same subnet as the AMP
•
Ethernet cable

Description
Sensors use UDP (User Datagram Protocol) to communicate with the AMP
server. UDP does not provide guaranteed delivery, so the sensors can be
set to retransmit unacknowledged messages from 1 to 4 additional times
before giving up and saving the data to report the next time the sensor
connects to the network.
Sensors can be configured to wait from 5 to 60 seconds before trying to re-
send an unacknowledged message to the AMP. Typically 5 seconds is
more than sufficient, but longer wait periods can be used if desired on
networks with bursts of high activity.
Each sensor device can be configured to use up to three different wireless
network settings, allowing for backups and fail-over scenarios. If using a
wireless network, the first network setting is required.
Select from the list of networks configured for the AMP.
For the optional, alternate wireless network, select from the list of networks
configured for the AMP.
