Chapter 4 Software Tools and 

Communication

Introduction

The default configuration DMC-40x0, with the default CMB-41012 communication board, has two RS232 ports and 
1 Ethernet port. An additional Ethernet port is available with the CMB-41022. The main RS-232 port is the data set 
and can be configured through the jumpers on the top of the controller.  The auxiliary RS-232 port is the data term 
and can be configured with the software command CC.  This configuration can be saved using the Burn (BN) 
instruction.  The Ethernet port(s) is a 10/100BASE-T connection that auto-negotiates the speed and half or full 
duplex.
The GalilTools software package is available for PC computers running Microsoft Windows

®

 to communicate with 

the DMC-40x0 controller.  This software package has been developed to operate under Windows and Linux, and 
include all the necessary drivers to communicate to the controller.  In addition, GalilTools includes a software 
development communication library which allows users to create their own application interfaces using 
programming environments such as C, C++, Visual Basic, and LabVIEW.  
The following sections in this chapter are a description of the communications protocol, and a brief introduction to 
the software tools and communication techniques used by Galil. At the application level, GalilTools is the basic 
programs that the majority of users will need to communicate with the controller, to perform basic setup, and to 
develop application code (.dmc programs) that is downloaded to the controller. At the Galil API level, the GalilTools 
Communication Library is available for users who wish to develop their own custom application programs to 
communicate to the controller. Custom application programs can utilize API function calls directly to our DLL’s. At 
the driver level, we provide fundamental hardware interface information for users who desire to create their own 
drivers.

Controller Response to Commands

Most DMC-40x0 instructions are represented by two characters followed by the appropriate parameters.  Each 
instruction must be terminated by a carriage return.  Multiple commands may be concatenated by inserting a 
semicolon between each command.
Instructions are sent in ASCII, and the DMC-40x0 decodes each ASCII character (one byte) one at a time.  It takes 
approximately 40 μsec for the controller to decode each command. 
After the instruction is decoded, the DMC-40x0 returns a response to the port from which the command was 
generated.  If the instruction was valid, the controller returns a colon (:) or the controller will respond with a
