Press select a fourth time to select the baud rate of the serial output. Press the maximum and minimum keys to change the display.

Press select a fifth time to select log interval hours. The log interval tells the Weather Report to send data to the internal memory and at what interval to do so. Press the maximum or minimum to change the display.

Press select a sixth time to select the log interval minutes. Press the maximum or minimum to change the display.

Press select a seventh time and a number between 0 and 255 will appear in the pressure/humidity window which represents output options. Enter the proper option number by pressing the maximum or the minimum keys. The output options control the selection of such things as AM PM, wind speed knots, auxiliary display and average wind speed output. (Look at the first item in the reference section called control options for more information, page 18.)

Press select a eighth time and the unit will return to a normal display.

Connect the 9pin female DB-9 plug of one end of the supplied RS-232 cable into the male DB-9 plug of the WR-25. Plug the other end of the RS-232 cable using either the DB-25 or the DB-9 female plugs into a open com port on your computer (all com ports on computers are either 9pin male or 25 pin males). If you do not use the supplied cable, please note that a null modem adapter is required to properly talk to a computer, the supplied cable has one built in.

The WR-25 via its RS-232 interface can communicate with computers running either the optional TWI-LOG program or standard computer communication programs. The WR-25 responds to the following ASCII characters sent by computers, with ASCII space delimited text.
