If you turn on Remote Disables Local while the amplifier is in Remote Mode, you will immediately lose the
ability to change anything from the RCP-2001 panel. Attempts to edit anything while this setting is ON and the
amplifier is in Remote Mode will result in the message *** REMOTE *** being displayed for a few seconds on
the RCP-2001 panel. You must return to the Control Mode setting in the Operate Menu, and set Local Mode,
before you can do anything else from the RCP-2001.
3.9.12 Reflected Power Fault Limit (17 61)
If the measured reflected power exceeds the Reflected Power Fault Limit, a High Reflected Power condition
exists. A fault or a warning will be reported, depending on the setting of Reflected Power Fault/Warning (see
3.9.13, below).
The Reflected Power Fault Limit is always represented as a power reading, in the current power units (dBm,
dBW, or Watts), regardless of the setting Reflected Measurement Type.
This fault limit can be disabled by turning it all the way up, such that it is displayed with a leading “>” symbol
(or through serial I/O by setting it for “>”).
The Reflected Power Fault limit can be set anywhere from 30 dB below the Nominal Power of the amplifier
plus the Reflected Power Calibration Offset, to 2 dB above the Nominal Power plus the Reflected Power
Calibration Offset, in 0.1 dB increments. This setting changes in 0.1dB increments, even if the power
readings are displayed in Watts.
Note that by adjusting the calibration offset, when the Reflected Power Fault limit is near one end of the
range, it is possible to disable it (if the setting is outside the range after the new calibration offset is set).
In a 1:1 system, the Reflected Power Fault High condition is suppressed (ignored) within 100 ms of a switch
transition.
This setting defaults to DISABLED, and is stored in non-volatile memory.
3.9.13 Reflected Power Fault/Warning (17 62)
This setting will allow the condition “High Reflected Power” to be reported as a fault or a warning. It has two
settings, FAULT and WARNING.
 If this setting is FAULT, a fault will be reported if the reflected power is too high, of if the Reflected
Power detector hardware fails. The red FAULT lamp on an attached RCP-2001 will be lit, and if the unit
is in a 1:1 system, it will be switched off-line.
 If this setting is WARNING, a warning will be reported if the reflected power is too high, or if the
Reflected Power detector hardware fails. The yellow WARNING lamp on an attached RCP-2001 will be
lit, and no 1:1 switch will occur.
Note that if you change this setting while a high reflected power condition exists, the reported Reflected
Power Fault or Warning will be changed as per your request. However, if a fault or warning has already been
reported due to a failure of the Reflected Power detector hardware, the reported condition will not change.
This setting defaults to WARNING, and is stored in non-volatile memory.
3.10 Control (18)
CONTROL messages can be used to set or query the state of various controls on the unit. Control messages
can either control a setting or read the setting back.
In general, commands sent to the unit can be one of two forms. The first form will query the value of a
particular control, the second will set the values. Some messages may vary from this format slightly. See the
individual message descriptions for more information.
The message from the controller to query the value of a setting must contain another data byte, which
immediately follows the instruction code (18). This byte is the sub-instruction, and specifies which particular
measured parameter you are requesting.
