Aprisa SR+ Product Description 1.5.0
Static IP Router – Human Error Free
To ensure correct operation, the Aprisa SR+ router base station alerts when one (or more) of the devices is
not configured for router mode or a duplicated IP is detected when manually added.
When the user changes the base station IP address / subnet, the base station sends an ARP unsolicited
announcement message and the remotes / repeaters auto-update their routing table accordingly. This also
allows the router that is connected to the base station to update its next hop IP address and its routing
table.
When the user changes the remote / repeater station IP address / subnet, a re-registration process in the
base station then auto-updates its routing table accordingly.
Terminal Server - Transition to Converged Ethernet / IP Network
Customers that are transitioning their SCADA network to an Ethernet / IP SCADA network, can
simultaneously operate their legacy serial RTUs, not as a separate serial network to the new Ethernet / IP
network, but as part of the Ethernet / IP network, by using the terminal server feature.
The Aprisa SR+ terminal server is an application running in the radio that encapsulates serial traffic into
Ethernet / IP traffic. For SCADA networks, this enables the use of both serial and Ethernet / IP RTUs
within an Ethernet / IP based SCADA network.
