Select the configuration that supports your SP201-SA’s port connections,
and press the Enter key. (The List of Valid LIMs shown is for a four-port
SP201-SA.)
Note: The standard choices shown below, in boldfaced numbers, include
120-ohm E1 interfaces. E1 interfaces may instead use 75 ohms over a BNC
connector. If you use BNC connectors, choose an appropriate combination
from the List of Valid LIMs above.
