Unit returns the oldest 5 Stored Statistics (including newly added Minimum and Average Receive Signal level),
which have not yet been read over the remote control in the reply form [CR]sub-body[CR]sub-body[CR]
sub-body[CR]sub-body[CR]sub-body, where sub-body = AA.ABB.BC.CD.DEE.E,FF.Fddmmyyhhmmss:
AA.A=Minimum Eb/No during sample period.
BB.B=Average Eb/No during sample period.
C.C=Max. Tx Power Level Increase during sample period.
D.D=Average Tx Power Level Increase during sample period.
EE.E=Negative value of Minimum Receive Signal Level in dB during sample period.
FF.F=Negative value of Average Receive Signal Level in dB during sample period.
ddmmyy = date stamp.
hhmmss = time stamp.
If there are no new events, the unit replies with RNN*. If there are less than 5 statistics to be retrieved, the
remaining positions are padded with zeros.
Note: RNN includes all information provided in RNS, plus Rx Signal level. Do not mix use of RNS and
RNN.

FSW=
None
Command only.
Forces unit to toggle Unit Fail relay to “fail” state for approx 500ms. If unit is part of a 1:1 pair and is currently
the ‘Online’ unit, this will force a switchover, so unit will then be in ‘Standby’ mode. The command is always
executed by the unit, regardless of whether it is standalone, in a 1:1 pair, or part of a 1:N system.
Note: This command takes no arguments.

Command or Query.
Enables or disables communications, via the FSK link, with a Comtech EF Data transceiver (ODU) in the
