Port Coquitlam, BC - Canada
NOTE: Because the telemetry is not true full duplex,
these messages must be sent immediately after
uplink range messages are received. Otherwise
collisions with uplink telemetry may occur.
Downlink will be ignored while uplink is in
progress.
These commands are detailed in the section below:
'-'x – QUERY
This command returns the current setting specified by
x, the first letter of one of the commands listed in the
table above in 'C'…'Y'. For example, the
acknowledgment to the command string '-V' is
'Vxxxx' where xxxx is the current assumed sound
velocity. In some cases, the current setting returned
may be the actual setting used by the altimeter,
instead of the setting last issued by the host. For
instance, the acknowledgment to the command string
is string '-Q' is 'Qxxxxx' where xxxxx is the actual
resolution in samples currently used, as opposed to
the maximum specified by issuing the 'Qxxxxx'
command string. Note that if the altimeter is paused,
that any new altimeter settings are not fully processed
until the unit resumes pinging - always wait until the
1007D resumes pinging before issuing the QUERY
command.
