CONSOLE CPU BOARD REPLACEMENT
It is possible to replace the console CPU board in a console IA or II (C04832) with the console II+
CPU board (C05836). To change the CPU PCB:
1. Turn off power to the console. Disconnect all external cables from the console. Remove the
four screws from the bottom of the console and carefully separate the upper housing from
the lower housing.
2. Remove all external cables from the console CPU board. Remove the three screws (1-5/8"
long) that hold the old CPU board. Remove the CPU board being careful not to bend the
pins on the keyboard connectors. Do NOT change any of the DIP switch settings on the
CPU board as this information will be needed later.
3. Remove the screw (1" long) from the keyboard that is in the middle of the keyboard near the
Manager's keyswitch.
4. Install new console II+ CPU board onto the keyboard. (NOTE: Be sure you have the correct
version of the program. If you have a SC I, you need a program version of 1.5. If you have a
SC II, you need a program version of 5.3 or above.) Carefully align pin 1 one of each
connector to pin 1 of the keyboard connector. Notice that this will leave the last four pins
(pins 21-24) of the P8 connector of the console II+ CPU unconnected.
5. Remove the flat washers from the three 1-5/8" long screws leaving the lock washers. Do
NOT install the flat washers on the new CPU board as it is possible to short some traces on
the board. Install the three 1-5/8" long screws and lock washers. Looking at the upper half
of the console with the VF display at the top and the Manager's keyswitch to the right, install
one screw in the upper lefthand corner, one in the lower lefthand corner, and one near the
center of the CPU. Do NOT overtighten these screws, as damage may occur.
6. Connect the RS-422 cable to P1. Connect the VF display cable to P4. Connect the
beeper/cash drawer cable to P5. Connect the Manager's keyswitch cable to P6. Connect
the mag reader cable to P7. Make sure all connectors are properly aligned; do NOT force.
7. Connect the power supply cable to P2, aligning pin 1 of the P2 connector with the orange
wire of the power supply cable. Looking at the upper half of the console with the VF display
at the top and the Manager's keyswitch to the right, pin 1 of P2 is the leftmost pin. If properly
installed, the two rightmost pins (6 & 7) of P2 will not be connected. Be sure that this cable is
installed properly before turning on the power, as damage may occur.
8. Carefully set the upper half of the console on the lower half. Replace the four screws in the
bottom of the unit. Connect all the external cables to the console.
9. Turn on the power. Put console into self-test mode and press 7. Using the console
configuration description earlier in this section, configure the console to match the DIP switch
settings on the removed console CPU board. Do NOT configure the console prnt/pad option
or any that follow it, as operational problems may occur. Once console is configured
correctly, press 0.
10. Console should be in the self-test mode. Using the self-test description for a console 1A+ or
II+, use the self-tests to verify the console is functioning properly. Do NOT use test 7, this
could corrupt your configuration. Once self-tests are complete, press 9. Console is now
ready for normal operations.
NOTE: If your console contains the cash drawer interface board, do not remove it. It
must be reconnected for the console to operate properly.
