switching hubs), make connections between devices, set the
sampling frequency, latency, bit-rate and other settings, as
well as simulate network setups in advance.
From the Start menu, choose “All Programs” and follow the
“CobraNet Discovery” arrow to the following menu. Select
“User Guide” to open the CobraNet Discovery User Guide
PDF file.
CobraNet Discovery can be used to list the equipment
on the network, view sampling frequency, latency and
bit-rate settings, as well as routing information, including
transmitter and receiver designations and bundle number
settings.
