Web Interface General The unit is accessible via a standard, unencrypted HTTP connection as well as an encrypted HTTPS (SSL) connection. The following web pages are available: Overview Page The front page, Overview, gives a real time view of the unit’s data. Readings for the internal temperature, humidity and dew point sensors along with all external sensors will be shown.
Logging Page The Logging page allows the user to access the historical data by selecting the desired sensors and time range to be graphed. Selected sensor values are logged into the data file at a rate of one point per minute. Please note that although data is logged once per minute, all sensor data used in the real time display and alarm functions is read at least once every 5 seconds for internal sensors and once every 30 seconds for external sensors.
Display Page The Display page allows the user to assign friendly names to internal and attached sensors as well as change the default temperature unit of measure for sensors. The display page also allows the user to select between the default and classic web page layouts. The default interface displays a vertical menu bar to the left of the main window, while the classic interface displays a horizontal menu bar across the top of the screen.
Alarms Page The Alarms page allows the user to establish alarm conditions for each sensor reading. Alarm conditions can be established with either high or low trip thresholds. The alarms are displayed in different sections based on the sensor the alarm is associated with. Alarm options include relays, Email and SNMP Traps.
Configuration Page The Configuration page gives the user the ability to enter and update network settings, time settings, email info and multiple other settings. See Unit Configuration (page 13) for details. Figure 7: Configuration Page GM1137 Revision Date: 02/13/2015...
Unit Configuration Network The unit’s network configuration is set on the Network section of the Configuration page. Settings pertaining to the unit’s network connection are: DHCP: Allows the unit to request a dynamic IP address from a server on the network. ...
The time, date, IP address and friendly name of the unit are displayed in the top of each web page. Figure 10: Date and Time Display Note: The time and date are not adjusted for daylight savings time. Setting the time zone offset forward and backward an hour will cause a gap or overwriting of logs, respectively.
SNMP The unit supports retrieval of all data via Simple Network Management Protocol (SNMP) v1 and v2c. In addition, alarm traps can be sent to up to two IP addresses. The SNMP configuration is entered on the SNMP section of the Configuration page. The default read community string is “public”...

alarm is created. The threshold value is typed into a data window when the alarm is created. Alarms are triggered based on the selected sensor’s data and the trip threshold type and value. Alarm settings can be edited or deleted at any time. Analysis of each unit is recommended before setting alarm thresholds as some of the values monitored by the unit are relative values whose scale will differ slightly between units.
Sensors Overview All internal sensors are measured every 5 seconds. External sensors are measured every 10 to 30 seconds, depending on the number of devices connected. Sensor data collected by Watchdog 15 units provides useful trend analysis data. While all values are not absolute in relation to a known unit, trend analysis of the data allows users to view changes and draw useful conclusions about what is happening over time in the monitored environment.
Accessories IP-Addressable Network Cameras The unit is able to interface with up to four IP-addressable network cameras. A live snapshot from each camera will be displayed on the unit’s Overview page. Clicking on a snapshot opens the camera’s website in a new browser window. Figure 18: Camera Images Camera model and IP address are entered on the Monitoring tab of the Configuration page.
Technical Support Firmware Version The firmware version is located in the upper right section of the web interface header, represented by v1.y.xx. Before contacting support, it is recommended that the Watchdog 15 unit first be updated to the latest firmware version. If this is not possible, please have the unit’s existing firmware version number available when contacting technical support.
