% ssh pi@polhe3pi2 ('hccuser' password)
% cd Documents
% scls # select 'acromag' entry, then type Ctrl-C to kill the program
# Set the limits
% for f in 0xf3 0xf5 0xF6; do ./setupAcro -l 36 -a $f; done
% for f in 0xf4; do ./setupAcro -l 46 -a $f; done
# Reboot the acromag controller using hcreboot6
# Then restart the software by (for example) running bash again
% bash
- Verify that the stripcharts are updating again and close the terminal window.
