Command Parameter/

Parameter block

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

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

ase

= 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).

aser_Powe

= 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.
