User Guide STATUS TERMINAL TIME UNITS No parameters Terminal Timeout Date_Time Units 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. 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. 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. 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 1st 2000 at 10:00:00) Note: The set time could drift by up to ±14 seconds a day. 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. 5.1.4 MCFG command message types The MCFG commands "Message_ID_x" parameter defines the following output types. Refer to Section 6 for further information on message output types.
