6.5 Menu system
When connected to the CS140, the user can enter the menu system by typing open id in their
terminal program then pressing the return key on their keyboard. The ID corresponds to the
sensor ID number. The sensor ID number can be in the range of 0 to 9. The factory default is 0.
NOTE:
The
open 0
command is not normally echoed. The terminal menu only gives access to more
common settings.
