1. Overview of the TempTale RF
2
System
The TempTale
®
RF
2
system consists of infrastructure components and dataloggers. The infrastructure
components, TempTale RF
2
Gateways (Gateways) and TempTale RF
2
Repeaters (Repeaters), are installed
permanently while the TempTale RF
2
Dataloggers(Dataloggers) travel with the cargo and report their
data when they arrive at a location that has an installed TempTale RF
2
infrastructure.
This manual presents information relevant to Sensitech personnel who have been trained to install the
TempTale RF
2
system.
Each location can only have one Gateway installed but many Repeaters. The Gateway receives and
sends data to and from Repeaters using RF signals and also connects to the Internet to make this data
widely available. Repeaters receive and send data or commands to the TempTale RF
2
Dataloggers
through RF signals. The infrastructure devices, the TempTale RF
2
Gateway and TempTale RF
2
Repeaters,
communicate with each other at 2.4 GHz frequencies. However, the system can accommodate smaller
installations as the Repeaters and Gateways can also communicate directly with the TempTale RF
2
Dataloggers at 868 MHz or 915 MHz frequencies. This unique feature makes the infrastructure scalable
and flexible for use at large or small installations.
The Gateway consists of a ruggedized, embedded computer loaded with the programs required to read,
process the data and connect to the Internet. The Gateway programs also performs data buffering and
error checking and data decryption to insure data integrity.
