9  CONNECTION TO A PC OR OTHER DEVICE 

Connection to a PC or other device requires the use of: 
1.  

Either a standard PCI or PCIA 

2.  

Or a suitable alternative power supply and RS422 conversion unit, which meets the 
specification of the anemometer. 

 
The PCIA supplies power for the anemometer and provides conversion of the RS422 signal sent by 
the anemometer and the RS232 signal required by a PC. The PCIA requires connection to a mains 
power supply or DC.  
 
The anemometer outputs data in RS422 format, which can be reconstituted to analogue via the 
optional PCIA. 
 
Baud rate options are: 
1.  

2400 

2.  

4800 

3.  

9600 

4.  

19200 

5.  

38400 

6.  

57600 

7.  

115200 (

Note:

 if changing a unit to 115200 Baud rate ensure that the connecting device 

supports 115200 baud e.g. RS422 converter, PC/Laptop etc.).  
 
 
Data format: 
8 data, 1 stop, no parity.
