Description
ALARMS Angle Angle is the threshold tilt angle of the sensor beyond which an alarm
will be flagged. The settable range is 0 to 90.0 degrees tilt and the
default is 45 degrees.
BS Attenuated_SCAL
E
BS_Av_Time
Noise_Gate
Measurement_
Period Attenuated_SCALE is the scalar for the attenuated backscatter, default
100%
BS-Av_Time is the back scatter average time in seconds (default 2.0).
Noise_Gate controls the noise threshold applied to backscatter.
Noise_Gate = -1000, all back scatter range is corrected.
Noise_Gate = 0.0-1000.0, standard deviation for noise threshold,
default 2.0. Only back scatter above this is range corrected.
Measurement_Period 0 or 2 to 600 (default 10). If set to 0 and the
CS135 is polled it will first take a measurement and then output the
message. If it is between 2 and 600 seconds then the CS135 will
continually update measurements and any poll command will output
the last measurement made.
CLOSE No parameters Closes the terminal interface to allow normal message output and saves
new settings to flash non-volatile storage.
DEFAULTS No parameters Loads factory defaults
HEATERS Hood
Internal
Laser Sets or reads heater settings as follows:-
Hood = 0, Hood blower and heater OFF
Hood = 1, Hood blower ON and heater OFF
Hood = 2, Hood blower ON and heater ON
Hood = 3, Hood blower and heater AUTO (default)
Internal = 0, Internal heater OFF
Internal = 1, Internal heater ON
Internal = 2, Internal heater AUTO (default)
Laser = 0, laser heater off
Laser = 1, laser heater on (default)
HELP No parameters Calls up a list of user commands with brief descriptions
HOFFSET Height_offset Height_offset is the offset to be added or subtracted in the range -
1000m to +1000m or -3281ft to +3281ft. Positive values are added to
measured height and negative values are subtracted from measured
height. The default is 0.
ID Sensor_ID Reads or sets the sensor ID, a single ASCII character, 0-9, a - z or A - Z,
case sensitive. Default ID = 0. Note that if a CT25K message is to be
used lower case letters are not allowed.
LASER Laser
Laser_Power Laser = 0, Laser off after power up (user must switch laser on).
Laser = 1, Laser on after power up (default).
Laser_Power = 20%-100%, default 100%.
LASEROFF No parameters Instructs the CS135 to turn the laser off until either a power cycle or the
sensor is instructed to turn the laser back on.
LASERON No parameters Instructs the CS135 to try and turn the laser on
LOADOS Module Loads new operating system into modules as follows: -
Module =1, DSP
Module =2, TOP
Module =3, PSU
This command must be sent using the XMODEM protocol. Refer to
Section 5.1.7 for more information.
MCFG Message_Interval
Message_ID_A
Message_ID_B
Message_ID_C Set or read message configuration.
Message_Interval is the message interval in seconds, 2 - 600 seconds,
0 gives polled messages, default 10.
