The above data are output as 16 bit twos complement numbers. In ASCII output format two hex
characters are output for each status address.
If an inclinometer is not fitted or faulty the above addresses are not output.
7.1.4 Software commands
Command Format
All commands are entered as an ASCII string consisting of a mnemonic, representing the operation,
and zero or more parameters separated by spaces and terminated by either <CR> or <CR><LF>. The
case of the characters in the command is ignored.
Commands are only valid whilst in the interactive mode, with the exception of the “enter interactive
mode” command and polled data request command.
ASCII Output String Termination
The ASCII output string terminator can be configured to be either <CR> or <CR><LF>. The
expression <TERM> is used to indicate either one of these string terminators.
Character Echo
Character echo can be enabled or disabled. If enabled, received characters are only echoed while in
interactive mode.
The Backspace Character
The anemometer will respond to the <BACKSPACE> character by deleting the previous character
from its command buffer, and echo <BACKSPACE><SPACE><BACKSPACE>.
The Escape Character
The anemometer will respond to the <ESC> character by deleting all characters currently in it’s
command buffer, and echo <TERM><TERM>.
