Operation
Once the RV-SMB is turned on, the terminal server will start. Radio A is always
powered, and Radio B is only powered when there is an active telnet session connected
to its TCP/IP port. Similarly, the internal antenna relay will remain connected to Radio A,
except when there is no active telnet session connected to Radio A and there is an
active telnet session connected to Radio B.

6.1
Operating in Single-Radio mode.
When only one radio is installed, it will be configured as Radio A. Starting a telnet
session with port 5001 will connect to Radio A.
6.2
Operating In Reserve-Standby Mode
When two radio modules are installed, it is possible to operate in reserve-standby mode
(backup radio is powered down until it is needed), use Radio A as the primary radio and
end the telnet session with Radio A when it is experiencing failure.
Note:
Do not transmit while switching radios.
6.3
Operating In Hot-Standby Mode
When two radio modules are installed, it is possible to operate in hot-standby mode
(backup radio is always powered, with TDMA timing synced to GPS). To do this, use
Radio B as the primary and only start a telnet session with Radio A when Radio B is
experiencing failure.
Note:
Do not transmit while switching radios.
