Sets the uplink pre-emphasis amount where d = 0 – 7. See
the 'PREEMPHASIS' description in the startup script
above for more information. This command can be used to
fine tune the uplink for various cables. When the
performance is optimized then this value can be
incorporated into the startup script to initialize the pre-
emphasis on boot-up. Note: this command is only supported
on towfish equipped with a 14102066 Multiplexer board.
Sets the uplink gain where d = 0 – 4. See the 'LBOGAIN'
description in the startup script above for more information.
This command can be used to fine tune the uplink for
various cables. When the performance is optimized then this
value can be incorporated into the startup script to initialize
the pre-emphasis on boot-up. Note: this command is only
supported on towfish equipped with a 14102066
Multiplexer board.
Sets the uplink source where d = 0 selects the normal
coaxial drive. Setting this to '1' selects the laser as the
source and deactivates the metallic uplink. See the
'LASER' description in the startup script above for more
information. Note: this command is only supported on
towfish equipped with a 14102066 Multiplexer board.
Sets the transmit waveform. This command should not be
accessed by the user as an incorrect setting can cause
serious data quality degradation.
Selects the responder frequency page where d = 0 –F
hexadecimal. The default is '7' which selects a frequency of
27.5 kHz. Increasing or decreasing this value changes the
responder frequency by 500 Hz.
Sets the responder divisor to 2^d, where d = 0 – 15. A value
of 15 turns the responder off.
Turns the altimeter transmitter on or off. Setting d = 1 turns
altimeter on, d = 0 turns the altimeter off.
