The program must begin with a % sign , just like any other program sent over RS-232, and the program must
end with a % sign. The data rate selected for the RS-232 port by Settings must be fast enough to keep up with
the rate of block execution of your program. If the data rate is too slow, the tool may be stopped in a cut when
you might otherwise expect continuous cutter motion. The highest standard RS-232 data rate available is
115,200 bits per second.
It is recommended that DNC be run with Xmodem or parity selected because an error in transmission will then
be detected and will stop operation of the DNC program without crashing. The settings page is used to select
parity. The recommended RS-232 settings for DNC are:
SETTINGS: 11 BAUDE RATE SELECT: 19200
12 PARITY SELECT: NONE
13 STOP BITS: 1
14 SYNCHRONIZATION: XMODEM
37 RS-232 DATA BITS: 8
Full duplex communication during DNC is possible by using the G102 command or DPRNT to output axes
coordinates back to the controlling computer. When DNC is running, BACKGROUND EDIT is not available.
To run DNC in graphics, you must select DNC first , then go to graphics display and send your program to the
CNC.
