QUIT Command
Use QUIT to revert to Access Level 0 from either Access Level 1 or
Access Level 2, as shown in Table 4.15.
Access Level 0 is the lowest access level; your SEL-3031 does not require a password
check to descend to this level (or to remain at this level).
RADIO Command
The RAD command is for viewing statistics and data on the radio link, as shown in
Table 4.16. The RAD command provides two important types of information.
➤ RSSI = Receive Signal Strength Indicator. The RSSI shows the
current strength of the receive signal from the radio. This command
helps you to refine antenna positioning. The RSSI is reported in dBm
and updates every time the RAD command is issued. The RSSI is
calculated from the latest 50 frequency hops averaged over time.
RSSI is very useful for optimizing performance on directional
antennas and monitoring signal strength.
