What are Base Units, Remote Units and Repeaters?
Base Units
A Base Unit can collect data measured by and recorded in Remote Units via
wireless communication, and send the collected data either by FTP or e-mail to
a server whereby the data can be downloaded to your computer via an external
network, such as the internet. Also, by setting Upper and Lower Limits, warning
monitoring can be carried out for each Remote Unit at each Location.
Remote Units
A Remote Unit is a Data Logger designed to measure and record temperature
and humidity. The wireless communication range between a Remote Unit and a
Base Unit, if unobstructed and direct, is about

500ft.
Repeaters
If wireless communication cannot successfully be carried out due to obstacles,
or if you wish to extend the wireless communication range, please add
Repeater(s) between Remote Unit(s) and the Base Unit.
About Registration
It is first necessary to register the desired Remote and Repeater Units (where
needed) to a Base Unit. It is possible to register them into Groups by place or
by purpose. Assign a Wireless Communication Frequency Channel for each
Group. Remote Units and Repeaters can only be registered to one Group at a
time.
