Table 6-2, Binary to Hex Conversions for Alarm Settings
The HMS discrete and analog alarms provide the capability to monitor and alarm various
power supply and environmental conditions and measurements. The alarms in the SCTE-
HMS propertyTable and the discretePropertyTable can be defined and set to provide a custom
monitoring system.
The following section provides an example and detailed information on how to set values, enable
or disable alarms in the MIB tables. For ease of reference they are in this sequence:
• An example of how set a temperature alarm
• A table to help convert the desired reported alarm states to hexadecimal for setting the MIB
• Commonly monitored parameters and recommended values
Example:
The alarms for
psTemperature below are set so that the normal temperature range is from
30°C to 45°C. If the temperature rises above 45°C, a casHI alarm will be sent to the alarmTable.
Anything over 50°C is considered a critical condition and will generate a casHIHI alarm. If the
temperature falls below the normal level of 30 degrees and casLO will be generated and if it
continues to drop below 0, a casLOLO will be generated. The temperature must rise above the
LOLO limit plus the deadband value of 3°C before the casLOLO alarm will change to a casLO.
The alarmEnable field is set to 0F Hex to monitor and alarm for all conditions.
