Figure 6 Radio Modem Satelline 3AS Epic with Optional
Display
When using UHF Radio Modem SATELLINE 3AS, the RS-232
communication module should be used to provide an additional RS-232
output for the radio modem, leaving the standard COM port (COM0)
free for maintenance purposes.
UHF Repeater Function
Message Routing is a built-in feature in the SATELLINE-3AS radio
modems, which makes it easier to build up a large radio modem
network. Message Routing features a versatile radio protocol, which
takes care of routing messages across a radio modem network. Only one
radio channel is required even in large networks. Any radio modem in
the network can act as a repeater and have a weather station interfaced
as well. The repeater can also be chained allowing message
transmission through several repeaters/weather stations.
Using the in-built functions in the SATELLINE-3AS radio modems,
two different types of repeater operations can be built:
1. The weather station having the radio modem will function as a
repeater for a group of other stations.
2. The radio modem alone installed in an enclosure with proper
powering can function as independent repeater for a group of
weather stations.
