M Series Data Radio – User Manual

Part C – Applications

Digipeater Systems

This configuration is used where all sites are required to communicate

via a repeater site. A repeater site is used because it has a position

and/or height advantage and thus provides superior or extended RF

coverage. The radio modem at the repeater does not have to be

physically connected to the application’s master site. Information from

the application’s master is transmitted to the repeater via radio, and the

repeater then relays this information to the other field sites. In this

scenario, the repeater is the master from an RF point of view, and the

application master is effectively a “remote” from an RF point of view,

even though it is controlling the data transfer on the system.

E Series Backbone Store and Forward

Systems (Using M Series Remotes)

Store and forward is used as a way of extending RF coverage by

repeating data messages from one site to another.

Example shows E Series Backbone with E or M Series remotes.
