Baud = 6, 19200 baud.
Baud = 7, 38400 baud.
Baud = 8, 57600 baud.
Baud = 9, 76800 baud.
Baud = 10, 115200 baud (default).
Bits_Parity = 0, 8 bits, no parity, 1 stop bit (default).
Bits_Parity = 1, 7 bits, even parity, 1 stop bit.
Bits_Parity = 2, 7 bits, odd parity, 1 stop bit.
Delay is the delay time in mS to TX (RS485 half-duplex mode only).
Range 0-1000mS, default 100mS.
STATUS No parameters Outputs CS135, serial number, DSP OS version, TOP OS version, PSU
OS version, time & date, blower heater mode, internal heater mode,
serial parameters, message parameters, tilt angle, units,
temperature/humidity, hood temperature, height offset, alarms,
warnings, PSU voltage and backup battery voltage.
Note: Refer to Section 5.1.5 for more information on this command.
TERMINAL Terminal
Timeout Sets CRC16-CCITT checking and the user terminal time out.
Terminal = 0, CRC16-CCITT off (default).
Terminal = 1, CRC16-CCITT on (reserved for future OS).
Timeout is the delay in minutes from 1 to 15 where the terminal will
automatically close if no characters are sent to the CS135. The default
is 10 minutes.
TIME Date_Time
Date is format yyyy/mm/dd
Time is format hh:mm:ss
yyyy=year, mm=month, dd=day
hh=hours, mm=minutes, ss=seconds
(i.e. time 2000/01/01 10:00:00, would set the time to January 1
st 2000 at
10:00:00)
Note: The set time could drift by up to ±14 seconds a day.
UNITS Units Sets measurement units and tilt correction for cloud height and vertical
visibility.
Units = 0, metres corrected by tilt.
Units = 1, metres not corrected by tilt.
Units = 2, feet corrected by tilt (default).
Units = 3, feet not corrected by tilt.
