port adhering to version 1.3, three 12-bit analog input ports with an auto-ranging voltage
input capable of measuring 0-10V and 0-20mA current loop measurements, and two digital
measurement and I/O ports. All sensors are capable of being configured separately and can
measure with one minute resolution.
5.1.6 Communication Interfaces
The device supports an RS232 serial interface and an embedded ZigBee Mesh radio
interface. Both interfaces are coupled with the WASUP message passing protocol which
supports inter-device networking th rough multiple physical mediums. In the case of ZigBee,
WASUP coordinates message passing and automatic routing for centralized data storage
and inter-device communications.
5.1.7 Removable Data Storage
The device supports a SD card interface for extended memory applications. The inser-
tion and removal of the card is detectable and permitted while the d evice has power. Card
sizes of 2GB and below are supported. Advanced security features of the SD card are also
not supported.
5.1.8 User Interfaces
The device has two easy-to-use methods for configuring operations. One method is to
use a LCD driven user interface. No PC or handheld computer is necessary to access device
function and to verify correct device operation. With an SD card, data storage functions
are also fully available. The alternate method using PC s oftware is able to interface to a
logger using the serial port. The software can also connect to a network of loggers using the
ZigBee network. The software handles the database operations on all the data collected by
all nodes in a given system.
