CALIBRATE TEMPERATURE EXTERNAL 
value 
Makes single point calibration with the external 
temperature sensor connected to the interface unit, the 
value should be between -99 and 99. 
CALIBRATE TEMPERATURE INTERNAL 
value 
Makes single point calibration with the boom (FSM102) 
temperature sensor in the measurement unit, the value 
should be between -99 and 99. 
Performs the calibration routine but does not change 
the calibration values. Prints the signal value with the 
current calibration coefficient. 
Hardware reset by watchdog circuitry, verification 
yes/no asked. 
Sets the fixed, predefined data message as the 
transmitted message type for system testing purposes. 
See section Message Formats on page 72. 
SIMULATE MANUAL_MESSAGE string 
User definable data message for system testing 
purposes. 
Disables simulation message sending and returns to 
normal operation mode. 
ELOG command alone lists the error log contents. The 
error log is cleared with the CLEAR parameter. 
SET MESSAGE SECOND TYPE 
message_number 
Selects the message type to be transmitted as the 
Second Message. 
SET MESSAGE SECOND TYPE MITRAS 
Selects the MITRAS Single Base emulation mode for 
the Second Message. The data message, message 
frames, and polling format are the same as they are in 
Vaisala MITRAS Transmissometer. 
MITRAS_DB 
Selects the MITRAS Double Base emulation mode for 
the Second Message. The data message, message 
frames, and polling format are the same as they are in 
Vaisala MITRAS Transmissometer. 
FD12MSG2 
Selects the FD12 message 2 emulation mode for the 
Second Message. The data message, message frames, 
and polling format are the same as they are in Vaisala 
FD12MSG7 
Selects the FD12 message 7 emulation mode for the 
Second Message. The data message, message frames, 
and polling format are the same as they are in Vaisala 
SET MESSAGE SECOND PORT DATA 
The Second Message is directed to the Data port. 
SET MESSAGE SECOND PORT 
MAINTENANCE 
The Second Message is directed to the Maintenance 
port. 
SET MESSAGE SECOND PORT MODULE 
(DMX501 only) 
The Second Message is directed to the optional 
communication module, for example, modem module. 
SET MESSAGE SECOND PORT NONE 
No Second Message is given to any port (default). 
The reception of the First Message has to be 
acknowledged by the ASCII character ACK (0x06). If no 
ACK is received within 500 ms after the transmission of 
the last character of the First Message or an ASCII 
character NAK (0x15) has been received, the First 
message is repeated. The First Message is repeated up 
The reception of the First Message needs not to be 
acknowledged. (default)
