ADFM Commands
configured from battery-backed RAM unless it receives a CR-
command or until the RAM loses its backup power.
Example: CR0 = loads into non-volatile RAM the command set last
stored in EEPROM (semi-permanent or user settings) using
the CK-command.
CR1 = loads into non-volatile RAM the factory default com-
mand set stored in ROM (permanent or factory settings).
CR keeps the present baud rate and does not change it to the
value stored in EEPROM or ROM. This ensures the ADFM
maintains communications with the terminal/computer.
CS - Start Pinging (Go)
Purpose: Starts the data collection cycle or recorder playback (same as
<Tab>
Format: CS
Description: Data Collection - Use CS (or <Tab> key) to tell the ADFM to
start pinging its transducers and collecting data as pro-
grammed by the other commands. If the TF-command is set
(time of first ping), the ADFM waits until it reaches the TF
time before beginning the data collection cycle. If you try to
record data (CFxxxx1), and data already exist on the recorder,
or the recorder is erasing, the ADFM will not start pinging and
will return a RECORDER NOT READY message.
Recorder Playback - This command also plays back the data
recorded to the recorder when the RD-command is a nonzero
value. The CF-command settings determine ensemble cycling
(manual or automatic) and output format (HexAscii or binary).
After the ADFM plays back the last ensemble, it sends a NO
MORE ENSEMBLES message.
CT – Turnkey
Purpose: Determines how the ADFM responds to a restart event.
Format: CT n
Range: n = 0, 1 (0 = off, 1 = on)
Default: CT1
Description: If Turnkey mode is on, the ADFM will attempt to ping at the
next chronological ensemble time.
