Programs are sent or received through the RS-232 port (Serial Port 1) located
on side of the control box (Not the operator’s pendant).
A cable (not included) is necessary to link the CNC control with the PC. There
are two styles of RS-232 connections: the 25-pin connector and the 9-pin con-
nector. The 9-pin connector is more commonly used on PCs.
.
WARNING! One of the biggest causes of electronic damage is a lack
of a good ground on both the CNC mill and the computer. The lack of
grounding will damage the CNC, or the computer, or both.
Cable length
The following lists baud rate and the respective maximum cable length.
9,600 baud rate: 100 feet (30 m) RS-232
38,400 baud rate: 25 feet (8 m) RS-232
115,200 baud rate: 6 feet (2 m) RS-232
The settings between the Haas control and the other computer must match. To
change the settings in the CNC control, go to the Settings page (press Setng/
Graph) and scroll to the RS-232 settings (or enter “11” and press the up or
down arrow). Use the up/down arrow keys to highlight the settings and the left
and right arrow keys to change the values. Press Enter when the proper selec-
tion is highlighted.
The settings (and defaults) that control the RS-232 port are:
11 Baud Rate (9600) 24 Leader to Punch (None)
12 Parity (Even) 25 EOB Pattern (CR LF)
13 Stop Bits (1) 37 Number Data Bits (7)
14 Synchronization Xon/Xoff
There are a number of different programs that can link with the Haas control.
An example is the Hyper Terminal program that is installed with most Microsoft
Windows applications. To change the settings on this program go to the “File”
drop down menu at the top left. Choose the “Properties” selection from the
menu and then press the “Congure” button. This will open up the port settings;
change these to match what is in the CNC control.
To receive a program from the PC, push the LIST PROG key. Move the cursor
