Date format for CDATE and ADJD is YYYYMMDD. CDATE<cr> CTEXT<cr> ADJD<cr> Examples: cdate Cal. info adjd Adj. date : 20091201 : VAISALA/HELSINKI : 20091201 View Order Code Use the CODE command to view the order code that has been stored in the probe. This command is useful if you need to order a new probe with the same options. CODE<cr> Example: code Order code : A12A01B0 View Serial Number Use the SNUM command to view the serial number of the probe. SNUM<cr> Example: snum Serial number : E3950006 VAISALA _______________________________________________________________________ 33 User's Guide ______________________________________________________________________ View Software Version Use the VERS command to display the software version of the probe. VERS<cr> Example: vers HMP60 / 1. 00. 0 Serial Line Output Commands Start Measurement Output Use the R command to start the continuous outputting of measurement values as an ASCII text string to the serial line. The output always includes readings for temperature, RH and Td. R<cr> Example: r T= 22. 6 'C RH= 22. 8 %RH Td= T= 22. 6 'C RH= 22. 5 %RH Td= T= 22. 6 'C RH= 22. 5 %RH Td= . . . 0. 3 'C 0. 2 'C 0. 2 'C Outputting the results continues in intervals issued with the command INTV. You can stop the output by entering the S command. Stop Measurement Output Use the S command to stop the continuous measurement output: S<cr> 34 __________________________________________________________________ M211060EN-A Chapter 4 ________________________________________________________________ Operation Output the Measurement Message Once Use the SEND command to output the measurement values once. If the probe is in POLL mode and line is not open for commands, specify the address of the probe to receive the measurement message. SEND [aaa]<cr> where aaa = Address of the probe, range 0 . . . Set with the ADDR command. Example (probe in STOP mode, no address needed): send T= 22. 7 'C RH= 20. 0 %RH Td= -1. 5 'C Example (probe in POLL mode, with address 10): send 10 T= 22. 8 'C RH= 20. 1 %RH Td= -1. 3 'C Configuring Serial Line Operation Set Serial Line Settings Use the SERI command to show or set the serial line settings. The new settings will be taken into use when the probe is reset or powered up. SERI [b p d s]<cr> where b p d s = = = = baud rate (300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600) parity (n = none, e = even, o = odd) data bits (7 or 8) stop bits (1 or 2) VAISALA _______________________________________________________________________ 35 User's Guide ______________________________________________________________________ Example (shows default settings): seri Baud P D S : 19200 N 8 1 Set Serial Interface Mode SMODE [xxx]<cr> where xxx = STOP, RUN, or POLL In STOP mode: outputting only when command is issued, any command can be used. In RUN mode: outputting automatically, only command S can be used. In POLL mode: outputting only when command is issued, any command can be used after the line has been opened using the OPEN command.
