ASCII Commands
To start the test, enter ANA AO301 R 9.0 at the Access Level 2 prompt:
=>>ANA AO301 R 9.0 <Enter>
Ramping Analog Output at 1.78 mA/min; full scale in 9.0 minutes.
Press any key to end test
BNAMES Command
(Binary Names)
Use the BNA command to produce the names of all device status bits reported in
the Fast Meter Data Block (A5D1) message in Compressed ASCII format, as
shown in Table 7.11. This command is only available as Compressed ASCII
response.
CAL Command
Use the CAL command to gain access to Access Level C. See Access Levels for
more information. Only go to Level C to modify the default password or under
the direction of an SEL employee. The additional commands available at Level C
are not intended for normal operational purposes.
CASCII Command
(Compressed ASCII)
Use the CAS command to produce the Compressed ASCII configuration mes-
sage. This configuration instructs an external computer on the method for extract-
ing data from other Compressed ASCII commands, as shown in Table 7.13. This
command is only available as Compressed ASCII response.
Upon receiving the CAS command, the device responds with the configurations
of all Compressed ASCII commands: CME, CST, CHI, and CSU.
CEVENT Command
(Compressed Event
Report)
Use the CEV command (Table 7.14) to obtain event report data in a Compressed
ASCII response. These data are similar to those data produced by the EVENT
command. When using the CEV command to retrieve event reports, the event
data are in a format suitable for use by PC software to display the event in oscil-
lographic form. See Section 9: Analyzing Events for further details on event
reports. When the CEV command includes any of the parameters listed in
Table 7.14 (e.g., CEV n), the report length is the number of cycles specified by
the LER setting (15 or 64 cycles). When using the CEV command without
parameters, the report length is 15 cycles.
