Galil DMC-2X00 用户手册

• Chapter 2  Getting Started 

For each axis that will used for stepper motor operation, the corresponding stepper mode (SM) jumper 
must be connected.  The stepper mode jumpers, labeled JP5 and JP7 are located directly beside the 
GL-1800 IC's on the main board (see the diagram of the DMC-2x00).  The individual jumpers are 
labeled SMA thru SMH and configure the controller for ‘Stepper Motors’ for the corresponding axes 
A-H when installed.  Note that the daughter board must be removed to access these jumpers.  Contact 
the Galil factory if stepper motor jumpers should be placed on your controller with each order for a 
special part number. 

The state of the motor upon power up may be selected with the placement of a hardware jumper on the 
controller.  With a jumper installed at the MO location, the controller will be powered up in the “motor 
off” state.  The SH command will need to be issued in order for the motor to be enabled.  With no 
jumper installed, the controller will immediately enable the motor upon power up.  The MO command 
will need to be issued to turn the motor off. 

The MO jumper is always located on the same block of jumpers as the stepper motor jumpers (SM).  
This feature is only available to newer revision controllers.  Please consult Galil for adding this 
functionality to older revision controllers. 

The Main and Auxiliary Serial Communication Ports are normally connected for RS-232 connection.  
The jumpers JP3 and JP4 on the DMC-2001 daughter-board allows the DMC-2000 to be configured 
for RS-422.  This can be specified as an option when the unit is purchased or the DMC-2000 may be 
re-configured by the user, please consult Galil for instructions.  Other serial communication protocols, 
such as RS-485, can be implemented as a special - consult Galil. 

The main and Auxiliary Serial Commutations Ports are normally connected for RS-232 connection.  
The jumpers JP4 and JP5 on the DMC-21001 daughter board allows the controller to be configured for 
RS-422.  This can be specified as an option when the unit is purchased or the controller may be re-
configured by the user, please consult Galil for instructions.  Other serial communications protocols, 
such as RS-485, can be implemented as a special - consult Galil.   

Located on the outside of the controller box is a set of 5 DIP switches.  When the controller is powered 
on or reset, the state of the dip switches are read. 

When this switch is on, the controller will perform a master reset upon PC power up.  Whenever the 
controller has a master reset, all programs and motion control parameters stored in EEPROM will be 
ERASED.  During normal operation, this switch should be off. 

When on, this switch will enable software handshaking (XON/XOFF) through the main serial port.   

When on, this switch will enable hardware handshaking through the main serial port.
