Connection
Communications between SV-Remote and Sierra View are handled via LAN. Where
there is a requirement for two or more control panels in different areas, additional SV-
Remote units can be cascaded from the first via RS422.
Network connection and setup
The network settings of the SV-Remote are configured entirely by the Sierra View.
Multiple SV-Remote configurations can be present on the same network, therefore a unit
does not automatically acquire remote units that it finds on the network; this has to be
done manually from the web interface.
First, ensure that both the Sierra View and SV-Remote units are connected to a common
LAN.
The Remote Control Setup Dialogue is entered from the Module Menu (refer to the
section on Using the web interface).
Note:
If installing multiple new SV-Remotes, it's a good idea to connect them one at a time to
the network, because they will all have the same default IP address and will therefore not
be distinguishable from one another.
Cascading multiple SV-Remote via RS422
Once the first SV-Remote has been connected to the Sierra View via LAN, any additional
remote units may be cascaded from the first, by means of a pin-to-pin RS422 cable. The
DATA OUT port of the first unit is connected to the DATA IN port of the second unit.
