The TWI_LOG program. TWI_LOG is an IBM PC software utility which enables the user with special
applications to communicate and set various functions of the WRL. Insert the TWI_LOG diskette
into your disk drive and type TWI_LOG then press enter.
Note: TWI LOG is no longer sent with the weather stations. The TWI Cal Windows program has
replaced TWI_LOG and is included with the weather station. If for some reason you still need the
TWI_LOG program it is available on our website at
www.texas-weather.com .
The first screen of the program will look this:
1 Com1
2 Com2
3 Modem
enter index of station name: ?
Pressing selection 1 accesses the WRL, if it is plugged into com1.
Pressing selection 2 accesses the WRL if it is plugged into com2.
Pressing selection 3 accesses the WRL via modems and phone lines.
WRL access can be modified by editing the twi_com.dat file on your TWI_LOG disk. To change 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.
