Description of Arguments
Query only.
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.
Command only.
Forces the software to clear the software statistics log.
Example: CAS=
Note: This command takes no arguments.
Command only.
Resets internal pointer to allow RNS? queries to start at the beginning of the statistics log.
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
form x, where:
0=Disabled
1=Enabled
Example: ODU=0 (selects Disabled)
