Alarm Configuration:
Alarm Func:
The following options are available:
Normal – The alarm relay is controlled by the channel alarm status.
Inactive – The alarm relay is forced to the “no alarm” state for testing.
Active – The alarm relay is forced to its “alarm” state for testing.
Latching – The alarm relay is “latched” by an instance of the alarm state, and remains in
this position until unlatched by manually selecting the adjacent Clr box.
Note: When an alarm is current, the border of the Configure Alarm Detail button will be red, and when the Channel is expanded,
the Alm Func box will also be red (refer above example).
Rly Mode:
The Relay Mode may be either Normally Released (N/R), i.e. it “operates” when an alarm is present, or Normally Operated (N/O),
i.e. it “releases” when an alarm is present.
I/P Func:
This selects the channel specific input function. An application for this feature is to use it with a PTT signal from the transmitter.
The following options are available;
Disabled – The input is not used.
PTT Low – An active LOW or “0” input signal is required. (A LOW is defined as <2.5vdc)
PTT High – An active HIGH or “1” input signal is required. (A HIGH is defined as >2.5vdc)
When the I/P Func input is enabled, it is used instead of the Threshold Power Level (configured on the Tx Port Channel
Configuration page) to determine if the alarmed parameter should be measured. If used with the transmitter’s PTT line, even if
the transmitter produces no RF output, but the PTT line activation is present, an alarm condition can be determined. If the
Threshold Power Level value was used instead, no RF level would be detected above the threshold level, so no measurements
(or resulting alarm states) would occur.
Specific Alarm Types:
When selected, either Tx Power, Tx I.L. or VSWR (or any combination thereof) alarm conditions on the affiliated ASM Tx channel
will initiate an alarm output condition on this CAM channel.
Defaults:
