DMC-3425 Chapter 2 Getting Started• 15
the entry has been selected, click on the OK button. If the software has successfully established
communications with the controller, the registry entry will be displayed at the top of the screen.
If you are not properly communicating with the controller, the program will pause for 3-15 seconds.
The top of the screen will display the message “Status: not connected with Galil motion controller” and
the following error will appear: “STOP - Unable to establish communication with the Galil controller.
A time-out occurred while waiting for a response from the Galil controller.” If this message appears,
you must click OK. In this case, there is most likely an incorrect setting of the serial communications
port. The user must ensure that the correct communication port and baud rate are specified when
attempting to communicate with the controller. Please note that the serial port on the controller must
be set for handshake mode for proper communication with Galil software. The user must also insure
that the proper straight-through serial cable is being used (no Null modem). See appendix for the
correct pin-outs for the serial cable.
Once you establish communications, click on the menu for terminal and you will receive a colon
prompt. Communicating with the controller is described in later sections.
Using Non-Galil Communication Software
The DMC-3425 serial port is configured as DATASET. Your computer or terminal must be
configured as a DATATERM for full duplex, no parity, 8 data bits, one start bit and one stop bit.
Check to insure that the baud rate switches have been set to the desired baud rate as described above.
Your computer needs to be configured as a "dumb" terminal that sends ASCII characters as they are
typed to the DMC-3425. Use the EO command to specify if the characters should be echoed back
from the controller.
Sending Test Commands to the Terminal:
After you connect your terminal, press <carriage return> or the <enter> key on your keyboard. In
response to carriage return (CR), the controller responds with a colon, :
Now type
TPA (CR)
This command directs the controller to return the current position of the A axis. The controller should
respond with a number such as
0000000
Communicating through the Ethernet
For Ethernet communication, connect the DMC-3425 to your computer or to a hub. If connecting
through a switch or a hub, a standard RJ45 Ethernet cable is used. If connecting directly to the PC, a
cross-over RJ45 Ethernet cable must be used.
Using Galil Software for Windows
The controller must be registered in the Galil Windows registry for the host computer to communicate
with it. The registry may be accessed via Galil software, such as WSDK or DMCSmartTerm.
From WSDK, the registry is accessed under the FILE menu. From DMCSmartTerm it is accessed
under the Tools and Controller Registration menu. In the Galil Registry, the DMC-3425 can either
be added manually with the New Controller button or the software can automatically try to find the
controller with the Find Ethernet Controller button.
The first registry option is to use the New Controller button. The DMC-3425 should be selected from
the models listed, with Ethernet selected as the mode of communication.
