Updating and Reconfiguring P2OS

after each startup. You may choose not to change the FLASH ROM values. Rather, you
record the new configuration values and set/reset them using the

p2oscf

tool described

earlier in this chapter.

Install either

compasscal(.exe)

revcountcal(.exe)

into the

bin

directory of your

Saphira distribution. Connect your robot's HOST serial port to the computer, by tether if

you plan to save the calibration parameter to FLASH ROM. Turn on the robot's Main
Power.

From an X-terminal (Linux/UNIX) or DOS command line, execute the calibration tool. The
default connection port is the first serial port on your computer:

COM1

for Win32 systems or

/dev/ttys0

for other Linux/UNIX systems. Specify an alternative port by providing a

startup argument.

For example:

% compasscal /dev/ttyS3

connects the

compasscal

calibration tool with the robot via the Linux computer's

/dev/ttyS3

serial port.

If the tool fails to connect the Saphira client with the robot server, it will tell you
"Connection refused" and hang. Press

control-c

to stop the program and try again

after fixing the serial connection. Typically, reboot the robot with its red

RESET

Console

button after an error.
