APMxxxx Series User's Manual
Digital Input:
Displays the ten (10) configurable digital inputs.
Input ID:
Enter a description for the digital alarm signal. Up to 16 characters may be entered.
Enabled:
Selects if this input is enabled.
Function:
Select the input mode for each of the Digital Inputs.
A "CAMX-X PTT" selection affiliates the digital input as a base station Tx PTT or RX UNSQ or other control line function as a
monitoring line for the base station assigned to that CAM Alarm Relay Output (see below). A "General Purpose" selection
identifies the Digital Input as an independent digital input for monitoring external equipment, etc
When the Function 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.
Other conditional alarming functionality for Receiver, Voting Shelf or other system equipment can be created using this Function
input selection.
Criteria:
Select the input state (LOW or HIGH) that signals an alarm condition.
Alarm Output:
These 10 rows configure the individual channel alarm outputs and PTT input settings. Selecting the Configure Alarm Detail
button on each row expands its display (refer above example). Selecting the Collapse button minimises the row display.
Alarm Source:
Either select the source of the alarm for each channel, or select "Alarm not in use" to disable the alarm.
Input/Channel:
Having selected the source, select the desired input/channel to be assigned to the SAM alarm.
