Base Receiver Station
The base receiver station configuration mode is used for the
collection of ALERT2 or legacy ALERT1 data at the network access
point. It is normally used in conjunction with the 115E-2-A2 Decoder-
Gateway unit.
Base receiver units are usually located very close to the receiving
antenna to ensure shortest RF cable can be used and connects to the
115E-2-A2 decoder-gateway unit using a RS-485 link (twisted pair).
The 115E-2-A2 then receives this RS-485 data and allows host devices
to connect via TCP to a standard ethernet connection. The decoder-
gateway can also be used to accept legacy ALERT1 protocol through
its RS-232 port to connect to existing ALERT1 decoders.
The ERT-A2 base receiver can also be installed with a RF splitter-combiner to allow single antenna to
be shared between legacy ALERT1 system and the ALERT2 protocol unit. The 115E-2-A2 allows both
connections and conversion of ALERT1 to ALERT2 as a concentration frame.
Capability Summary:
-
Base station receiver VHF/UHF radio
-
RS-485 A2 data provides a medium distance connection up to 1km (4000ft) to decoder
configurable data rate.
-
Output communications can be either RS232 or RS485 could support ALERT2 Binary modes
-
Decoder-Gateway connects RS-485/232 A2 data to Ethernet, HFEM, HyData, ALERT1 or
converts into industrial protocols such as Modbus or DNP3 for Environmental or Industrial
applications
-
Internal IO diagnostics:
o
Supply monitoring (battery/supply in)
o
RSSI, temperature, internal faults
Repeater Station
–
Full Duplex High Capacity
Repeater and receiver units can be linked using
the RS-485 interfaces which allows several useful
configurations to be formed to solve more
complex network design challenges.
For very large systems the backbone of the
network data frame capacity can be increased
twofold by using a second radio frequency and
running in a full duplex mode.
The repeater will aggregate ALERT2 data frames
when there is very high incoming data flows to
achieve the most efficient use of radio channel.
