• CPU DIP Switches:
• 8-position DIP switch S2 is set according to the type of serial PI fixtures on the job
(CE/E-Motive). For CE fixtures all switches should be in the ON position (left). The
number 1 switch (lower) may be placed in the OFF position to start a CE fixture self-
test. The test exercises all of the characters potentially displayed on the fixture and is
viewed on the fixture itself. For E-Motive fixtures all switches should be in the OFF
position (right).
• 2-position DIP switch SW5 is used to update system software. Leave in OFF (Left)
positions unless updating software.
See “Updating System Software” on page 2- 43.

Updating System Software
System software updates are initiated using two-position DIP switch SW5 on the SCE-CPU
board. Before updating, the system first checks for a USB drive in the CPU board USB port. If
the update USB drive is present, the system will copy the software from the USB to the micro-
SD card, replacing the current version files on the card. The system will then update from the
SD as directed by the DIP switches.
1. Place the car on Inspection and remove power to the controller. If this installation is a
duplex, also remove power to the other car or disconnect CAN 3 from the other car.
Power should be applied to
only
the car for which software is being updated or CAN 3
should be disconnected from the other car.
2. If you are updating from a USB drive, insert it into the USB port on the SCE-CPU board.
3. Position the DIP switches to direct the update:
• Both switches ON (Right): Update all system devices regardless of existing software
version (recommended).
• Switch 1 (top) ON, Switch 2 (bottom) OFF: Update only when source file is different
from existing.
4. Restore power to the controller. The process will begin, either copying USB files first or
immediately beginning the update from the SD card.
Depending on how many files are on the USB, there may be a
delay of around thirty seconds before copying begins. Update time
depends on the number of devices being updated but is generally
about fifteen minutes. The touch screen keeps you appraised of
what is happening but it will go blank for a few minutes while the
display processor itself is updating. (The SPC processor LED will
flash while the screen is blank to assure you that the process is
continuing properly. Each blink equals about 3% complete.)
5. Part way down on the left of the Firmware Update screen you will see an indication for
SPC (CSC): either PENDING or SUCCESS. If instead FAILED is displayed, press the
RSTC push button.
6. When updating is complete, the touchscreen will tell you to place both switches on the
DIP switch back to the OFF (Left) position to resume normal operation.
If new LCD graphics are available, the graphics file will be copied to the display processor as
part of the startup sequence.
7. Take car off machine room inspection.
8. Leave the USB drive in place until the system is fully operational (graphics have com-
pleted loading).
