there is a power fault during a firmware update. If EEPROM corruption occurs, your controller may not operate properly. In this case, install the UPGD Jumper and use the update firmware function on the Galil Smart Terminal or WSDK to re-load the system firmware.

Setting the Baud Rate on the DMC-3425

The jumpers labeled “9600” and “1200” at JP1 allow the user to select the serial communication baud rate. The baud rate can be set using the following table:

JUMPER SETTINGS		BAUD RATE
9600	1200	--
OFF	OFF	19200
ON	OFF	9600
OFF	ON	1200

The default baud rate for the controller is 19.2k.

Selecting MO as default on the DMC-3425

The default condition for the motor on the DMC-3425 is the servo on (SH) state. This will enable the amplifiers upon power up of the controller. This state can be changed to the motor off (MO) default by placing a jumper at JP2 across the MO terminals. This will power up the controller with the amplifiers disabled and the motor command off. The SH command must then be given in order for the servos or steppers to operate.

Stepper Motor Jumpers

The DMC-3415 is user configurable to control either a servo motor or a stepper motor. The DMC- 3425 is factory default to servo control, but may also control two steppers if ordered from the factory as a DMC-3425-Stepper.

To configure the DMC-3415 for stepper output, two jumpers must be placed on the controller. First, the SMX jumper at location JP2 must be installed. This configures the board for step/direction output. Second, the jumpers at location JP3 must be moved from the MC position to the SD position as shown in Figure 2.2. This configures the output pins on the controller to output step and direction instead of the analog motor command.

The configuration for two stepper motors on the DMC-3425-Stepper is handled at the factory. The same procedure is used, placing jumpers on SMX and SMY at location JP2, and moving the SD/MC jumpers at location JP3. A board modification is also required, which should only be handled by Galil technicians.
