DAVIS Vantage Pro - Testing Commands

Page 9 of 52
Beware that some systems may translate a new line character into both a new line and a carriage
return which will cause intermittent operation when using a Vantage Pro2 console.
In the following command examples, lines starting with “>” are set to the console, and lines
starting with “<” are received from the console.
Character symbols
Symbol Value Name
<CR>
0x0D Carriage return, “\r”
<LF>
0x0A Line Feed, “\n”
<ACK>
0x06 Acknowledge
<NAK>
0x21 Not Acknowledge
<CANCEL>
0x18 Bad CRC code
<0xdd>
0xdd Character code specified in hex.
1. Testing commands
"TEST"
It sends the string “TEST\n” back. Mostly useful when using HyperTerminal for testing a
connection to the console.
Example:
>"TEST"<LF>
<"TEST"<LF><CR>
"WRD"<0x12><0x4d>
It is the same command sequence used by earlier Davis weather stations to read the Station
Type value. The station will respond with an <ACK> and then a one byte identifier, which
can be one of these values:
Value Station Value Station
0 Wizard III 4 GroWeather
1 Wizard II 5 Energy Enviromontor
2 Monitor 6 Health Enviromonitor
3 Perception 16 Vantage Pro, Vantage Pro 2
Example:
>"WRD"<0x12><0x4D><LF>
<<ACK><16>
"RXCHECK"
It sends the Console Diagnostics report. The following values are sent on one line as a text
string: total packets received, total packets missed, number of resynchronizations, the largest
number of packets received in a row., and the number of CRC errors detected.
