Dispatcher Configuration File
Configuration | Value | Explanation |
|---|---|---|
ip | 192.168.23.126 | IP address of the Lantronix box. |
port | 10001 | Port that is used for Vaisala, this is port 1. |
format_str | form 9.4 "P=" P " " U6 6.4 "T=" T " " U3 6.4 "RH=" RH " " U4 \r \n | Format statement of the output from the Vaisala. At dispatcher start up and at every new connection, this value is sent to the Vaisala. The #.# sets the number of characters (first # ) and the second # sets the number of characters after the decimal point. There must be a space between the characters that notes what the value is (such as P=) and the actual value (the P). The code uses the characters (P=, RH= or T=) to determine what the next value is. |
poll_time | 5 | Time between reads of the Vaisala in seconds. |
