SR Compatible
The SR Compatible option enables over-the–air point-to-multipoint interoperation between an Aprisa SR+
network and New Aprisa SR radios. The default setting is unticked.
When the Aprisa SR+ ‘SR Compatible’ option is activated, the Aprisa SR+ locks its modulation to QPSK (as
per the New Aprisa SR modulation) and disables functionality which is not available in New Aprisa SR for
full compatibility / interoperability operation.
This compatibility option allows the user a smooth migration to Aprisa SR+ when higher speeds of 120,
60 kbit/s (at 25, 12.5 kHz channel sizes), Adaptive Coding Modulation, full duplex and more features are
required.
Note
: Any mix between the New Aprisa SR and Aprisa SR+ in the network will force the whole network to
work in SR Compatible mode.
Ethernet Operating Mode
The Ethernet Operating Mode defines how Ethernet / IP traffic is processed in the radio. The default
setting is Bridge.
Option
Function
Bridge
Bridge mode inspects each incoming Ethernet frame source and
destination MAC addresses to determine if the frame is forwarded
over the radio link or discarded.
Gateway Router
Gateway Router mode inspects each incoming IP source and
destination IP addresses to determine if the packet is forwarded
over the radio link or discarded. In this mode, all Ethernet
interfaces have the same IP address and subnet.
Router
Router mode inspects each incoming IP source and destination IP
addresses to determine if the packet is forwarded over the radio
link or discarded. In this mode, each Ethernet interface has a
different IP address and subnet.
