5 OPTIONS
5.1 Hardware Hold-off
An optional feature that allows hold-off of the 1007D pinging
for ping rate control.
In the standalone 80x modes this is hold-off/trigger feature
that functions the same as in older 80x sounders. It is
available as a TTL compatible input signal. The altimeter
samples this hold-off input signal before the start of each ping
and will start the next ping if de-asserted (left floating or set
to +5V). Pinging will be paused while the hold-off input is
pulled down to zero volts. However, during this time the
altimeter can still process incoming messages.
5.2 External Synchronization
In MS1000 mode, this is a signal compatible with the
MS1000 system synchronization method and can be used to
connect to one or more MS1000 altimeters or scanning sonar
heads in order to synchronize the pinging of all of the units. It
is a TTL compatible signal that can be configured as either
input, output, or bidirectional in the MS1000 PC software
application.
When this option is installed, it requires that a special
connector also be installed that provides extra connections for
this signal.
