Galil DMC-13X8 Step 2. Install Jumpers on the DMC-13X8

Chapter 2 Getting Started • 18 USER MANUAL

To configure the DMC-13X8 for stepper motor operation, the controller requires a jumper for each

stepper motor and the command, MT, must be given. The installation of the stepper motor jumper is

discussed in the following section entitled "Installing Jumpers on the DMC-13X8". Further

instruction for stepper motor connections are discussed in Step 7c.

Step 2. Install Jumpers on the DMC-13X8

The DMC-13X8 resides in the 16-bit short I/O space of the VME system. The base address of the

DMC-13X8 is set at FFF0. The address jumpers at JP10 are used to select the specific address for the

DMC-13X8 in the VME system. Placing a jumper on an address A4 through A15 makes that location

a 0.

For example, to set the controller address to FFE0, a jumper is placed on location A4.

JP1 contains two jumpers, MRST and UPGRD. The MRST jumper is the Master Reset jumper. With

MRST connected, the controller will perform a master reset upon PC power up or upon the reset input

going low. Whenever the controller has a master reset, all programs, arrays, variables, and motion

control parameters stored in EEPROM will be ERASED.

The UPGRD jumper enables the user to unconditionally update the controller’s firmware. This jumper

is not necessary for firmware updates when the controller is operating normally, but may be necessary

in cases of corrupted EEPROM. EEPROM corruption should never occur, however, it is possible if

there is a power fault during a firmware update. If EEPROM corruption occurs, your controller may

not operate properly. In this case, install the UPGRD Jumper and use the update firmware function on

the Galil Terminal to re-load the system firmware.

The inputs and limit switches are optoisolated. If you are not using an isolated supply, the internal

+5V supply from the PC may be used to power the optoisolators. This is done by installing jumpers on

JP3.

Stepper Motor Jumpers

For each axis that will be used for stepper motor operation, the corresponding stepper mode (SM)

jumper must be connected. The stepper motor jumpers, labeled JP5, are located directly beside the

GL-1800 IC on the main board (see the diagram for the DMC-13X8). The individual jumpers are

labeled SMX, SMY, SMZ and SMW.

The DMC-13X8 controller supports vectored hardware interrupts. The jumper locations JP9 and JP11

are used to select the IRQ line which will interrupt the bus. IRQ1 through IRQ7 are available to the

user as hardware interrupts, and are set at location JP9. The second set of jumpers located at JP11 are

labeled IAD4, IAD2 and IAD1. The summation of these jumpers should be set equal to the IRQ

selected on JP9.

For example, suppose the VME host for a certain system requires a hardware interrupt on IRQ 5. A

jumper would therefore be placed at location JP9 on the pins labeled IRQ5. In addition, IAD4 and

IAD1, which add up to 5, will be jumpered at location JP11.

The vector and the conditions triggering the hardware interrupt on the DMC-13X8 are set through

software using the EI or the UI command. The DMC-13X8 will provide the hardware interrupt to the
