4.  Applying power will turn on the green LED power indicator. 

Step 4. Installing the Communications Software 

After applying power to the computer, you should install the Galil software that enables 
communication between the controller and PC.  

The CD-ROM used for the following installations is 

Version 11/01.   
 
Using DOS: 

Using the Galil Software CD-ROM, go to the directory, 

July2000 CD/DMCDOS/DISK1

.  Type 

INSTALL 

at the DOS prompt and follow the directions. 

Using Windows 3.x (16 bit versions): 

Explore 

the Galil Software CD ROM and go to the directory, 

July2000 CD/DMCWIN

.  Run 

DMCWIN16

 and follow the directions.  The Windows Servo Design Kit (

WSDK16

), which is useful 

for tuning servos and viewing useful controller information, can be downloaded off the CD as well.  
However, 

WSDK16 

is a purchase only software package and is password protected on the CD.  

Contact Galil for purchase information. 

 
Using Windows 95 or 98 First Edition: 

The HTML page that opens automatically from the CD-ROM does not contain the necessary software 
for Windows 95 or Windows 98 First Edition.  Instead, 

Explore

 the CD and go to the 

July2000 CD 

folder.  To install the basic communications software click on 

DMCTERM 

and then run the 

application, 

DMCTERM

.  Another terminal software is called 

DMCWIN32 

and is located under 

July2000 CD/DMCWIN

.  The Windows Servo Design Kit (

WSDK32

), which is useful for tuning 

servos and viewing useful controller information, can be downloaded off the CD as well.  However, 

WSDK32 

is a purchase only software package and is password protected on the CD.  Contact Galil for 

purchase information. 

 
Using Windows 98 Second Edition (SE), NT 4, ME, 2000 or XP: 

The Galil Software CD-ROM will open an HTML page automatically as soon a  Instead, 

Explore

 the 

CD and go to the 

July2000 CD 

folder.  To install the basic communications software click on 

DMCTERM 

and then run the application, 

DMCTERM

.  The other basic terminal software is called 

DMCWIN32 

and is located under 

July2000 CD/DMCWIN

.   The Windows Servo Design Kit 

(

WSDK32

), which is useful for tuning servos and viewing useful controller information, can be 

downloaded off the CD as well.  However, 

WSDK32 

is a purchase only software package and is 

password protected on the CD.  Contact Galil for purchase information. 

Step 5. Establishing Communication between the DMC-14XX and the host PC 

Communicating through the RS-232 Serial Communications Port 

Connect the DMC-14XX serial port to your computer via the Galil CABLE-9PIN-D (RS-232 Cable). 

Using Galil Software for DOS 

To communicate with the DMC-14XX, type TALK2DMC at the prompt.  Register the controller as a 
DMC-1412 and assign the proper baud rate and comm port.  Once you have established 
communication, the terminal display should show a colon, :.  If you do not receive a colon, press the 
carriage return.  If a colon prompt is not returned, 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 serial cable is being used, see appendix for pin-out of serial cable.
