Command Descriptions
STATUS
(Access Level 1 or 2)
SEL-DTA2 self-test status can be examined with the STATUS command. The
instrument also automatically executes the STATUS command whenever a
self-test indicates a warning or failure condition. The instrument sends output
to communications Port 1.
STATUS report format:
SEL-DTA Display/Transducer Adapter Date: 1/1/91 Time: 01:10:23
SELF TESTS
RAM ROM SET DISPLAY
OK OK OK OK
The status of four tests is reported in the last two rows of the report. If a RAM,
ROM, or settings (EEPROM) test fails, the IC socket number of the defective
part is indicated. A display failure is indicated in the last column.
TIME
(Access Level 1 or 2)
To read the internal clock, type TIME <ENTER> . To set the clock, type
TIME followed by the desired setting. Separate the hours, minutes, and
seconds with colons, semicolons, spaces, or slashes. To set the clock to
23:30:00, enter:
TIME 23 30 00 <ENTER> or TIME 23:30:00 <ENTER> , etc.
A quartz crystal oscillator provides the time base for the internal clock.
Since the SEL-DTA2 clock synchronizes with the relay clock approximately
every five seconds, changing the time with this command is ineffective if the
SEL-DTA2 is normally connected to a relay. This feature allows the
SEL-DTA2 to benefit from the IRIG-B time code used by the relay.
VERSION
(Access Level 1 or 2)
Executing the VERSION command returns the FID string to the computer
terminal screen. Use this command to verify which version of firmware is in
the SEL-DTA2 chassis. See
Appendix A: Firmware Versions and Relay
Compatibility for a definition of firmware covered by this release of the
manual. The following is an FID number with the Part/Revision number in
bold:
FID= SEL-DTA-R207 -V22-D921109
