Checking System Status

Checking Alarms and Input Frequency

Symmetricom 5087B Operations and Maintenance Manual Rev. E
You can check the system status and the model and software version
remotely.
If you have connected a monitor to the open collector ALARM output
connector, that device will also receive alarm information.
The system can report current alarms and latched alarms.
To check system status
• Type: S
You do not need to type a carriage return or line feed.
The system returns Sabcde,fghij\r\n where
• abcde is current status.
• fghij is latched alarms and changed status since the last status
request.
Both abcde and fghij are hexadecimal numbers, with each bit
position representing one output. LSB (farthest right) is output 1.
MSB is the input. Bits 0–15 are latched alarms. Bits 16–19 are
change in status bits.
Latched alarms remain active in the current status field and latched
status field until the problem is corrected. Changed status bits are
cleared upon next status request.
Example: S00001,00001
This example shows an output 1 failure that is active and occurred since
the last status request.
Table 2 defines each status or alarm bit position.
