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,

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).

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.
