RADAR COMMANDS
RADAR COMMAND OVERVIEW
Commands are used to control the operation of the radar. These are sent over the RS422 UART link.
Commands are immediately followed by an operator that indicates the required action. Not all operators are
supported for all commands. Where an operator is used and it is not supported the radar will respond with a
warning message. The table shows the operators that are used by the radar.
Operator Operation
= Set something to a value e.g. *LS=50<CR> sets low speed threshold to 50
? Respond with value or values
^ Set default value for parameter
$ Provide help on the command
! Do something e.g. *REBOOT! Reboots the radar
Command Operators
Where a command is used to enquire or set a radar parameter the radar will respond in a set way. The radar
will respond with a hash, #, followed by the command name, operator used and then the value of parameter or
parameters.
For example
*LS=50<CR> Radar responds with #LS=50km/Hr<CR>
*LS?<CR> Radarrespondswith#LS?50km/Hr<CR>
*FSN?<CR> Radarrespondswith#FSN?11111111,22222222,3333333,4444444<CR>
Where a function requires to provide more feed back than can fit on a single line the radar will prefix each line
with a # followed by the command name. An example of this is the MOTOROLA-FLASH command.
Communications Command Interpreter Error message
If the user enters incorrect syntax or tries to set a parameter out of range this will be reported as an error.
The radar will return #ERROR followed by a description of the error.
