User's Manual

A system consists of two or three types of hardware, and two pieces of software:
•
Database Software on a PC or Access Point
•
Tehama Configuration Utility
•
One Base Unit or Access Point
•
A variable number of Sensors units, each with 2 AA batteries
•
A variable number of Repeater units (optional, depending on size of installation) with
external DC power supply.
Warning
Tehama Installation Tool
You should have received a copy of the Tehama Configuration and Installation Tool software.
This runs on a Windows based PC. More detailed information can be found in the separate
manual for that software.
The tool can be run on the PC either prior to or during a site installation, or when new MDT/
Sensors are added to a system. The tool is used to add configuration data to the database.
Examples of configuration data include the name, type, and location of equipment an MDT/
Sensor is connected to, and alarm trigger settings for the different MDT/Sensors.
MDT/Sensor Configuration
All MDT/Sensors come from the factory with a default factory-set configuration. The following
parameters can be configured in the field by qualified installation staff through a UART style
interface and terminal program running on a PC. There are no parameters which can be
configured on the Base or Receiver. The most common field programmable settings are:
•
Monitor Type, defined as the type of device the unit is attached to for measurements.
This includes temperature via thermocouple or thermistor, humidity, CO2, Pressure, or
various pulse type inputs from Utility meters or dry contact outputs from door sensors or
other devices.
•
Transmit Interval, defined as the time between scheduled transmissions of temperature
data. A temperature measurement is taken every Transmit Interval, and the data
transmitted within 60 seconds after the measurement. The units for this parameter are
seconds, and the default value is 900 seconds (15 minutes).
•
Measure Interval, defined as the time between scheduled temperature measurements.
This is used in conjunction with Temperature Change (see below) and must be smaller than
