Pressing selection 3 accesses the WRL via modems and phone lines.
WRL access can be modified by editing the
configuration load twi_com.dat into a text editor and change to your preference. The first station in
this example is identified as green. It is set up on com 1 at 2400 baud, no parity, eight data bits and
one stop bit. BIN, DSO, CD0, and CS0 are various configuration parameters that must be in the
string. The TWI station is configured as a remote unit. A modem would be connected to com1 set at
2400 baud, no parity, 8 data bits and one stop bit. The ATE0QV1M1X4S0=0 is the modem
configuration string required by this particular modem. The DT1,214,234-1309 is the phone number
where the remote unit and its modem are located. Please note that TWI_LOG does not support
Com3 or Com4.

Pressing F1 enables the user to communicate with the WRL using all the commands referred to in
the Communicating with the WRL (page 14) Section of this manual.
Pressing F2 instructs the computer to retrieve data from the WRL and place that data in a file on
the disk drive. Only new data will be written to disk during successive retrievals. Any number of
WRL's or WPS' can be accessed and their data will be put in different files on the drive. There will
be two files written on to your drive, log_day.??? and log_rec.???. Log_day. ??? has the minimum
and maximum values and log_rec.??? has the individual records. Each file has a file extenuation
that corresponds to the ID number of each weather unit. The ID number can be changed through
the calibration (F5) routine in Twi_Log. For example if you downloaded data from a unit with the ID
of 124 the data for that unit would be found in log_rec.124.
Pressing F3 displays the data written on disk. Press the up arrow key to go up or down one record
