During this mode, the telemetry type (RS232, RS485,
RS422) is fixed by a factory-configured setting, and
cannot be changed. This mode emulates the Model
809 Altimeter, providing a pin-compatible serial
interface for output/control of altitude measurements
via a computer.
d)
MS1000 mode
: operates as an MS1000 device over an
RS232 or RS485 telemetry interface, and is controlled
by MS1000 host software running on a PC. In this
mode, the 1007D detects the telemetry type (RS232,
RS485) used by the MS1000 host PC. RS-485
telemetry is the most flexible, allowing multiple
1007D altimeters and MS1000-compliant digital
sector scanning sonar heads to be connected to a single
cable.
The MS1000 mode can also entered from any of the
standalone
807, 808, or 809 modes if MS1000 telemetry is
detected. However, this is possible only if the altimeter is
configured for a telemetry type that agrees with that used by
the MS1000 host PC. Further details regarding 1007D setup
and control with the MS1000 software can be found in the
MS1000’s help utility or in the MS1000 Operator’s Manual.
The 807 , 808 , and 809 modes are collectively referred to as
the standalone 80x modes throughout this document.
2.2 Range Resolution
The 1007D altimeter is capable of resolving distance at very
high resolution, limited only by the altimeter's maximum
sampling rate (307.2kHz or 2.4mm) and sample memory size
(16000 samples). This implies that distances can be measured
down to 2.4mm resolution for maximum ranges up to 38
meters.
