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:

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.

Com1 COM1:2400,N,8,1,BIN,DS0,CD0,CS0

Com2 COM2:2400,N,8,1,BIN,DS0,CD0,CS0

Modem COM1:2400,N,8,1,BIN,DS0,CD0,CS0 ATE0Q0V1M1X4S0=0 DT1,214,234-1309

After you make your selection the following screen will appear:
