ADFM Commands
C-1.3 Data Output Processing
After the ADFM completes a data collection cycle, it sends a block of data
called a
data ensemble . A data ensemble consists of the data collected and
averaged during the ensemble interval (see TE-command). A data ensemble
can contain header, leader, velocity, correlation magnitude, echo intensity,
and vertical-beam data (selected by the WD-command).
ADFM output data can be in either hexadecimal-ASCII (HexAscii) or bi-
nary format (set by CF-command). The HexAscii mode is useful when you
use a terminal to communicate with, and view data from, the ADFM. The
binary mode is useful for high-speed communication with a com-
puter/program, or when you want to record densely packed data. You
would not use the binary mode to view data on a terminal because the ter-
minal could interpret some binary data as control codes.
When data collection begins, the ADFM uses the settings last-entered (user
settings) or the factory-default settings.
The ADFM automatically stores the last set of commands used in non-
volatile RAM. The ADFM will continue to be configured from battery-
backed RAM until it receives a CR-command or until the RAM loses its
backup power. If the ADFM receives a CR0, it will load into battery-
backed RAM the command set you last stored in EEPROM (semi-
permanent user settings) through the CK-command. If the ADFM receives
a CR1, it will load into battery-backed RAM the factory default command
set stored in ROM (permanent or factory settings).
Table C-13 gives a summary of the ADFM input commands, their format, a
brief description of the parameters they control, and lists the factory default.
NOTE. This table applies to firmware version 6.37. When newer firmware
versions are released, some commands may be modified or added. Read
the README file on the upgrade disk or check MGD’s web site for the
latest changes.
