COMMAND STRUCTURE
A command to an HI-4422/FP4000/FP5000 probe consists of 1)
a command letter, followed by 2) possible parameters, 3)
terminated with a carriage return. When it completes the
command, the HI-4422/FP4000/FP5000 responds with a string
consisting of 1) a start character (":"), 2) the command letter,
followed by 3) data, if required, and terminated with 4) a carriage
return. If the command does not require the probe to return any
data, the probe simply responds with the command letter and a
carriage return. If an error occurs, the probe responds with an
error code, as detailed in Appendix A.
Command Description
Axxx Axis enable/disable. x = "E" means
enable, x = "D" means disable, xxx order is
X axis, Y axis, Z axis
B Read battery voltage.
Cx Set baud rate.
x = 1 sets rate to 2400 baud
x = 2 sets rate to 9600 baud
Note: The baud rate does not change until the HI-4422/
FP4000/FP5000 has been powered down (turned off), let sit for at
least 10 seconds, and then powered up (turned on) again.
Dx Read probe data.
x = 1 enables short form output
x = 2 enables long form output
Rx Set range. x = 1, 2, 3, 4 or N (next range)
Sx Sleep timer. x = number of seconds to wait
for a command before putting the probe into
the sleep mode. In the sleep mode, the
HI-4422/FP4000/FP5000 changes to a low
power mode that increases battery life. In
the sleep mode, the probe can only
recognize the receipt of a command; it
cannot recognize a command. The first
command sent when the probe could be in a
sleep mode may be an ASCII null character
or any command. Following the receipt of
this "wakeup" character, a command can be
sent to which the probe will respond.
