RS-485 serial interface
Wiring
1.
Make the RS-485 wiring of the WXT510 as described in Chapter
5,
Wiring
.
2.
In the data logger end, combine the "Data+"wires of each
WXT510 to the logger "Data +" wire. Connect the "Data-" wires
of each WXT510 to the logger "Data -" wire.
Communication protocol
Set the communication protocol to ASCII polled (with or without
CRC) or NMEA query. When using NMEA query, the wind message
should be set to XDR (aWU,N=T).
NOTE
Supervisor error messaging parameter must be disactivated with
aSU,S=N for each WXT510 on the bus.
ASCII, polled
The WXT510s on the bus shall be assigned with different addresses.
(e.g. aXU,A=0,1,2,...).
Example: A bus with three WXT510s:

1 communication settings:
0XU,A=0,M=P,C=3,B=19200,D=8,P=N,S=1,L=25

#
2 communication settings:
1XU,A=1,M=P,C=3,B=19200,D=8,P=N,S=1,L=25
WXT510
#
3 communication settings:
2XU,A=2,M=P,C=3,B=19200,D=8,P=N,S=1,L=25
Example
: Composite message queries to the sensors 1 and 3 are
assigned as follows:
