The CR1000, SETPTR, DATE, TIME command is used to control where the next data will be
read from the CR1000 Final Storage using a date and time stamp value. The DATE and TIME
parameters must be within the start and end pointers time stamp boundaries. For instance,
assume the Table data record pointer is pointing at the last record entry which happens to be
3000. The user can not, in this example, set the pointer to a number larger than 3000, or cannot
set the date/time values to a time beyond the time stamp of the last record. The CR1000,
SETPTR, DATE, TIME command will search through the CR1000 Final Storage memory and
set the pointer to the first data array that is equal to or greater than the given date and time. The
search will take a few seconds to locate the desired data point.
The CR1000, SETPTR, XXXX, G command allows the operator to set the pointer to a
numerical location where XXXX is a record number and G is a group number (1-16). This may
be known, or can be read using the CR1000, STAT command. (545B Radios Only)
5.8.4 Data Retrieval Hole Collection
Data retrieval “hole” collection refers to the process of collecting data that was missed during the
normal operation of data acquisition. For example, if several data reports were missed last week,
they can be retrieved without having to retransmit all of the data from the missing data to the
present time. The “hole” is referred to as a “swath”. There are two commands for this purpose.
One command is used to specify the swath in terms of date and time, and the other command
specifies the swath in terms of record numbers in the final storage. The random data “hole”
collection process does not interfere with normal sequential data collection.
The CR1000,TSWATH,BEGIN-DATE-TIME,END-DATE-TIME,{TX} command is used to
specify a time-swath. The begin and end times are each given as both a date and time. For
example, the command, CR1000,tswath,12/01/02,00:00,12/01/02,12:00,TX will collect and
transmit all data records for all tables from midnight to noon on 12/01/02. The optional TX
indicates the data is to be transmitted. If the TX is omitted the data will be displayed on the
maintenance port but not transmitted.
5.8.5 Update Interval
The command CR1000, INTERVAL, N sets up the number of seconds between scans for data
from the CR1000 final storage. If N is set to OFF then the radio internal SCHED command can
be used to schedule UPDT, TX commands at any particular time or interval. If N is set to a
number from 1 to 32767 seconds, an internal timer triggers an UPDT, TX type of action to scan
