Description of Arguments
Command or Query.
Rx Symbol Rate in the form x, where:
s=Symbol Rate in Msps
Example: RSR=20.000000 (20 Msps.)
Note: Refer to Sect. 1.5 Summary of Specifications for available symbol
rates for each mode.
Command or Query.
Adaptive Equalizer status in the form x, where:
0=Disable
1=Enable
Example: AEQ=1 (Adaptive Equalizer enabled)
Command or Query.
(CDI-40 ASI module only) Indicates whether the ASI Rx Frame Size is 188 or
204 bytes, in the form sf, where:
s = interface slot ( 1 or 2 )
f = frame size
0 = 188 bytes
1 = 204 bytes
Example: ARF=11 (Interface Slot 1 set to 204 byte frame size)
Command or Query.
Unit returns the redundancy auto/manual mode of the unit in the form x, where:
0 = Manual
1 = Automatic
Example: ASW=0 (Manual Mode selected)
Query only.
Units returns the value of the estimated BER in the form ab x 10
are the value. Last two bytes are the exponent. Returns 0.0E+00 if the demodulator
is unlocked.
Example: BER=4.8E-03 (BER = 4.8 x 10
Command only.
Forces the software to clear the software events log.
Example: CAE=
Note: This command takes no arguments
Command or Query.
Sets or queries the user-defined Circuit ID string, which is a fixed length of 24
characters.
Valid characters include: Space ( ) * + – , . / 0 9 and A thru Z
Command Only
Retrieves a previously stored configuration from the specified configuration
location (0 to 9).
Example: CLD=4 (retrieve configuration from Location 4)
