Murata Electronics North America 910M Manual Do Utilizador

 
The procedure below provides a quick demonstration of the WIT910. 
1.  Attach a transceiver to each computer, preferably between 5' and 30' apart for 

convenience.   

2.  Start WinCOM running on both computers   If you prefer, almost any other serial 

communications program such as Procomm or QModem set for 9600 bps will also 
work. 

3.  Turn the radios on and use the function keys to set DTR and RTS to 1  (if you are 

using a terminal program other than COM24, these are typically set automatically).  
The radio should respond by setting both DSR and CTS to 1, and transmit a short 
sign-on message including the firmware version and whether the unit is configured as 
a base or remote.  Watch the states of the hardware control lines on the status bar as 
you do this.  The DCD indicator should be lit on the base station.  After a few 
seconds, the remote unit will acquire the base station's signal and also assert its DCD 
signal. 

4.  Access modem control mode for each unit.  To access modem control mode, use the 

F1 key to toggle DTR to 0 and back to 1 and then press the F3 key, which sends the 
":wit2400" escape sequence.  If you are not using COM24, simply turn the radio off 
and back on and then type ":wit2400" (must be lower case, no backspace characters).  
The transceiver should echo back “

” to indicate that you have entered modem 

control mode.    Check the remote unit's hopping pattern by entering "wn?" at the 
prompt.  The remote should respond with "0", the default setting.  Check that the base 
station's hopping pattern matches this by entering "wn?" at the base station. 

5.  Exit control mode by entering "z>".  Do this for both radios.  At this point, you 

should be able to type characters into either radio and see them appear at the other 
side.  If you are using WinCOM, you can press the F6 key to transmit a repeating test 
pattern. 

6.  For a range test, disconnect the remote station from the computer and power supply.  

The DCD indicator should remain lit as long as the base station is in range..   

7.  Exit COM24 by pressing the ESC key.
