1.3 Description (continued)
The End Devices transmit up to 300 feet/91m (zED) or 3280 feet/1000m (zED-P/-LCD/
-AA/-CCELL/-DC-H2), without obstructions or interference, to a "Coordinator" connected
directly to an Ethernet network and the Internet. The wireless system complies with IEEE
802.15.4 operating at 2.4 GHz and the user can switch to different communication
channels to avoid interference with other wireless technologies (e.g. Wi-Fi).
To achieve robust and reliable wireless communication, End Devices retransmit data
adaptively to the environment so that power consumption is optimized in harsh conditions.
The Coordinator also provides error detection mechanism for inactive communication and
diagnostic information including signal strength and data transmission success rate to
help trouble shooting potential wireless system installation issues.
The zSeries system allows you to monitor and record Temperature, Relative Humidity,
and Barometric Pressure over an Ethernet network or the Internet without any special
software-just your Web Browser.
We offer a selection of End Devices for a variety of applications. End Devices can take
thermocouple types J, K, T, E, R, S, B, C, N and L (DIN J) measuring temperatures up to
2320ºC from two different locations. Also, End Devices are available with built-in
sensors, with external sensor probes, and with both built-in and external sensors. The
external sensors are designed for harsh environments such as outdoor weather, in HVAC
ducts, freezers and refrigerators.
For example, you can select one End Device that has one internal and one external sensor
to monitor temperature and humidity both inside and outside a climate-controlled facility.
Each zSeries Coordinator can directly support up to thirty-two (32) End Devices and a
maximum of 8 Coordinators can be setup in the vicinity. The Coordinators include AC
adapters to operate on any voltage worldwide from 100 to 240 Vac and 50 to 60Hz. The
Coordinator connects directly to an Ethernet Network or the Internet. Unlike an RS232 or
USB device, it does not require a host computer.
The zSeries Coordinator is an independent node on the network sending and receiving
data in standard TCP/IP packets. It is easily configured from a Web Browser and can be
password protected. From within an Ethernet LAN or over the Internet, the user simply
types the IP address (such as 192.168.1.200) or an easy to remember name (such as
"ServRoom" or "Chicago5") and the Coordinator serves a Web Page with the current
readings.
The device can trigger an alarm if variables go above or below a set point that you
determine. Your alarm can be sent by email to a single user or to a group distribution list,
including text messages to Internet enabled cell phones and PDA’s. The "Mail Notifier"
software is free and easy to use program for this application.
The zSeries wireless sensor system is easy to install, simple to operate, and features
award-winning iServer technology with an Embedded Web Server that requires no
special software.
The zSeries system serves Active Web Pages to display real time readings and charts of
temperature, humidity, and barometric pressure. You can also log data in standard data
formats for use in a spreadsheet or data acquisition program such as Excel or Visual
Basic. iLog is a free and easy to use program for logging data to Excel.
The virtual chart viewed on the web page is a Java™ Applet that records a chart over the
LAN or Internet in real time. With the zSeries system there is no need to invest time and
