TEALwatch® Power Monitor Quick Start GuideI. Quick-Start Section 1.1 What is the TEALwatch® Power Monitor The TEALwatch® power monitor is a low-cost embedded power monitor utilizing a web based interface for remote monitoring capability. The TEALwatch® power monitor is a 3-phase power monitor that can be installed as an option in your TEAL power subsystem, monitoring the mains voltage at the power entry point for the OEM equipment such as Semiconductor Automated Test or Medical Imaging equipment. The monitoring interface is standard Ethernet 10base-T. If your network is connected to the Internet, the TEALwatch® allows you to monitor the line voltage being supplied to your system from anywhere in the world at any time of day, using standard Internet web browser software, 24x7. No special software is required. The TEALwatch® also features programmable triggering parameters and has built-in non-volatile storage for multiple waveforms captured on triggered events with 128 samples per cycle resolution. Embedding an Ethernet connected web-based low-cost power monitor into a permanently installed Original Equipment Manufacturer’s (OEM) 3-phase power subsystem gives the user the ability to monitor their sites 24x7x365. As compared to the more traditional temporary power monitoring for OEMs, having a monitor permanently installed at each site can help prevent costly and repetitive site problems by identifying if the AC power is related to a specific site problem anytime. To make an embedded power monitor solution feasible, the device must be low cost, and to capture typical power quality events, it must be high performance. The TEALwatch® enables our customers to reduce their service costs by helping to diagnose any correlation between the AC power and any system issues that may have occurred.
1.2 What comes with the TEALwatch®
The TEALwatch® Power Monitor consists of two sub-assemblies, the Power/Divider PCBA
The TEALwatch® option, when specified, consists of two subassemblies that are installed within the TEAL power subsystem. One subassembly is the open frame power supply and voltage divider board (Power/Divider PCBA), and the other is the enclosed TEALwatch® monitor box, which is a Linux based web server hardware platform with proprietary software and firmware to monitor AC line voltage and trigger waveform capturing with AC line anomalies. No special software is required for operation of the TEALwatch®. Connection to a network is via a standard Ethernet 10base-T cable and the user interface is via standard Internet web browser software. Each TEALwatch® power monitor has a unique and customizable IP address. A manual is included, and the web browser software interface contains an online help section (the HELP tab near the top of the page) that is always available as part of the TEALwatch® interface. In addition, the most up to date information is available at the TEALwatch® web-site, www.tealwatch.com. NOTE: The RJ-45 Ethernet port may have a tool-removable plug installed at the factory as an agency approval requirement. This Ethernet plug may require a small slot screwdriver (or the equivalent such as a pocket knife blade) to push up the locking tab located on the bottom of the plug. The locking tab is simply a shortened version of the tab that you normally press up with your fingers to remove an RJ-45 cable (or your phone plug).
1.3 What do you need to connect to the TEALwatch® The TEALwatch® interface is accessed through a standard Ethernet 10base-T network via an Ethernet connection on the TEALwatch® itself (normally at the top-front of the PDU, although your location may vary.First, you need a PC or laptop. Second, you need standard web browser software, such as Internet Explorer, Netscape, or FireFox (which you would normally use to access the Internet). Third, you need an Ethernet cable or 2 cables, depending on you connection method. There are three basic ways to connect your computer (or network) to the TEALwatch® power monitor via Ethernet as shown below Ethernet Router - This is the simplest and easiest method of connection, although it requires a router and two (2) standard Ethernet cables. You can use a standard Ethernet multi-port router such as the Linksys BEFSR41 (a 4 port router that typically costs about $50 - $60 at your local electronics superstore) shown below.

Network Connection – The second option is to directly connect the TEALwatch® power monitor to your local Ethernet network. This option requires your System Administrator to make sure the Ethernet port in the room or facility is enabled in the network. Then, simply connect the TEALwatch® to the network Ethernet port with a standard Ethernet cable, and access the TEALwatch® by opening your web browser software (on a PC connected to the same network) by entering the default IP address of the TEALwatch®. The factory default IP address for the TEALwatch® is set as "192.168.1.200". If you have trouble connecting to the TEALwatch®, please contact your System Administrator before contacting TEAL. Direct Connection – The third option is to directly connect your laptop or PC to the TEALwatch® Ethernet port. This method requires an Ethernet compatible laptop or PC and a crossover Ethernet cable (as opposed to a standard Ethernet cable). You will likely need to reconfigure your Network settings within your PC, and you will typically need Administrator rights to your PC to do this. The process for directly connecting to the TEALwatch® is as follows:
For Windows XP:
For Windows 2000:
If you have any questions or are running an OS different from Windows XP or 2000, please contact the TEAL Marketing Department.
1.4 How to hook up to the TEALwatch® Simply plug one end of an Ethernet cable into the RJ-45 jack located on the TEALwatch® power monitor, plug the other end into your router, network connection, or directly to the PC or laptop (note that direct connection requires a crossover Ethernet cable). See section 1.3 above for details on your specific connection means.
1.5 Where to find the IP address of the TEALwatch® The IP address for each TEALwatch® power monitor is located on the TEALwatch® tag on the TEAL power subsystem as well as on the label of the TEALwatch® box located inside the TEAL power subsystem. The interior label also has space for writing in a new IP address if the user customizes the web address. The default IP address is " 192.168.1.200" unless otherwise noted.
Note that TEAL provides space on the TEALwatch® monitor box label for documenting a new IP address. This label is located on the top of the TEALwatch® monitor box, and is usually easily accessed by removing the top cover of the TEAL power subsystem. TEAL recommends use of a permanent marker for documenting the new IP address on the label.
1.6 How to connect to the TEALwatch® Although you do not need any special software to connect to the TEALwatch®, you may need to have administrator rights to your PC or laptop. One reason is to make sure the Java™ applet can run in your browser. Please review the Status Information section regarding Live Data of this manual below, which describes how to install the Java™ software. Second, you may also need to modify the network connection settings if you are directly connecting a PC or laptop to the TEALwatch® power monitor (direct connection requires a crossover Ethernet cable).
1.7 Description of the TEALwatch® user interface home page On opening the TEALwatch® user interface window with your web browser software, the first page that will open is the home page. The home page contains basic information detailing specific identifiers for this individual TEALwatch®, such as firmware version, location identifier, Real Time Clock status, etc. A sample screenshot of the home page is shown below.

Please review the "HOME – TEALwatch® Product Information" section for a full description of the information on the home page.
1.8 How to check the operating status of the TEALwatch® You can check the operating status of the TEALwatch® either remotely or locally. 1.8.1 Remote Status Check - You can always check the status remotely by opening your web browser to a connected TEALwatch® using it’s IP address (default IP address is 192.168.1.200). If the TEALwatch® is operating normally, you will be able to open the web site and review data, etc. If the web site for that TEALwatch® does not respond, there could be several reasons. First, the power may be removed from the subsystem, which will remove power from the TEALwatch®, and the web server will not be operating. Second, it could be your local network is not responding, and you can check this by trying to access other web sites. Third, the TEALwatch® may require a software or hardware reset. If this is the case, TEAL recommends that you try a normal refresh of your web browser software. If the web site is still not responding, you may need to apply the software reset located under the Advanced tab of the TEALwatch® user interface (see section 1.12 for details). If the web site is still not responding, you may need to check the hardware status of the TEALwatch® locally.
1.8.2 Local Status Check - There are three status LED indicator on the front panel (see the figure below).

If the TEALwatch® is working normally and connected to an Ethernet 10Base-T compatible network or device, there are two LED indicators on the Ethernet connector that show system status. On the bottom left side of the Ethernet connector is a green LED, which flashes ON to indicate that a compatible network has been found. This green LED, when flashing, will mean that the TEALwatch® and the network are connected. If this LED is OFF, this indicates that a network connection has not been established. On the bottom right side of the Ethernet connector is an orange LED, which flashes ON to indicate Ethernet communication is in process. This orange LED, when flashing, will mean that both the TEALwatch® and the network are communicating normally. If you still cannot access the TEALwatch® web site, then there may be a connection problem or network problem with your PC. The main TEALwatch® indicator is located to the left of the Ethernet connector. This green LED is the heartbeat indicator of the TEALwatch®. When things are operating normally, this indicator pulses about 2 flashes per second, similar to a heartbeat. If this LED is ON solid, aside from the first 60 seconds of turn-on, then the TEALwatch® may require a hardware reset. If the LED is not lit, this could indicate 1 of 2 things. First, there is no power to the TEALwatch®, which may be caused from an upstream circuit breaker being shut off, etc. If power is being supplied to the TEAL power subsystem, but the LED is not lit, the TEALwatch® may require a hardware reset. A hardware reset is accomplished by using a paper clip (or equivalent device) to push the recessed RESET button, accessed through a small hole to the right of the Ethernet connector. Press and hold the RESET for 3 seconds. Normal operation should resume within about 60 seconds, indicated by the flashing green status indicator to the left of the Ethernet connector. If normal operation does not resume, please refer to the Frequently Asked Questions (FAQ’s) and Troubleshooting Guide in this manual.
NOTE: You should set and verify the Real Time Clock when you apply power to the power monitor to make sure the time is reasonably accurate. Refer to Section 3.8 for instructions on setting the Real Time Clock.
