1. Basic System Configuration

Flash ROM Version Up (Firmware ROM Upgrade) Procedures (cont'd)

DIP Switches

Note:

When updating the ROM, the DIP switches on the back of the

machine must be set properly. Follow the Setting the DIP Switches

procedure below.

Setting the DIP Switches

Remove the screw marked with an asterisk (*) from the Controller

PWB at the back of the machine and rotate the plate part to access

the DIP switches. See illustration.

Note:

There are two DIP switches on the Controller: the Diag Mode

Switch (on the left) and the Write Protect Switch (on the right).

The switches are set to the Protect mode (switches are in the Up

position) during normal operation. Protect mode is the default. In

order to write to the ROM, the switches must be changed to the

down position (Diag Mode). This releases the write protection.

Upon completion of the upgrade procedure, remember to return

the switches to the Up position (Write Protect), and then rotate the

plate back over the DIP switches to the original position, and

tighten down the screw.
