Preface
Frick Controls has released the latest version of the Quan-
tum HD Unity Control System. The redesigned micro-
processor, referred to as the Q6 Processor Board, is the
brains of the system. The Q6 Processor Board combines
the functions of the Q5 Processor Board and the Interface
Board into a single board.
Features
The Q6 Processor Board includes the following features:
• 4 USB ports
• 10/100/1000 Mbps Ethernet port
• 1 RS-422 port
• 3 RS-485 ports (2 dedicated, 1 available)
• External HDMI video monitor port
• LED indicators to verify proper operation of onboard
systems such as power, serial communication, and
Ethernet.
• 4 GB of RAM memory
• Battery to maintain date and time
External serial communications previously made possible
through the Frick Controls Interface Board are now directly
supported by the Q6 processor board.
Power up Sequence
When powering up, the following sequence of events are
indicative of a functioning Q6 Processor Board:
• All LEDs turn on solid, excluding the CFast, SATA, and
SATA Host LEDs
• Active, User 1, User 2, and SD Card LEDs turn off
• Rx and Tx LEDs for COM1-COM4 turn off
• CFast and SATA Host LEDs will blink rapidly to indicate
activity
• The display shows a black screen with a graphic
• The display changes to a white screen with the text
“Open Embedded” and a loading bar
• The display changes to a blue screen with the text
“Quantum HD Loading”
• The Active LED (blue) begins to blink slowly
• Ethernet port LEDs turn on to indicate network link
speed (if used)
• The display now shows the Operating Status (Home)
screen
After the Q6 Processor Board has completely powered up,
the following sequence of events is indicative of proper
communication to the analog and digital boards:
• Rx and Tx LEDs for COM4 on the Q6 Processor Board
will blink rapidly to indicate activity
• Analog and Digital I/O board’s Rx and Tx lights will blink
rapidly to indicate activity
• The Power LED on each I/O board will be on solid, and
the Active LED will blink slowly
This power-up sequence is the first thing that needs
checked when troubleshooting the Q6 Processor Board.
Troubleshooting
If the Operating Status screen is not shown, check the fol-
lowing items:
1. If no LEDs are turned on, check AC and DC power (re-
fer to the Power Supply section of this manual)
2. Check if the lighting of LEDs is occurring as described
in the What Occurs When Applying Power section
• If the power-up sequence continues to repeat with-
out displaying the Operating Status (Home) screen,
there is a booting problem
3. Check all plugged connectors for proper seating
4. Check for any error messages that are displayed while
booting
• Write down any error messages exactly as they ap-
pear (taking a picture with a mobile device is useful
as well)
5. Check that the software is OK:
• Is the correct software installed?
• Was new software just installed?
6. Check the display (if the Q6 Processor Board appears
to be booting properly and the display is not illumi-
nated)
• If only a portion of the display looks darkened, one
of the backlights has failed
• If the entire display is dark, use a beam-type light
source such as a flashlight to look for a ghost-type
image (something is displayed on the screen but it is
very dark)
• If a ghost-type image is present, the display back-
light cable is improperly seated, the display backlight
has failed, or the Q6 Processor Board has failed
• Verify that both the LVDS display cable and the
backlight cable are firmly seated (it may be neces
-
sary to remove the LVDS display cable from the back
of the display and re-seat it to ensure it is connected
properly)
WARNING
This is a small connector. Observe caution when
unplugging and re-plugging this cable to avoid any
damage due to excessive force.
Battery Function
The processor board uses a battery to maintain the cor-
rect date and time for the purpose of stamping warnings
and shutdowns as they occur. If the date and time are
not being maintained properly, this may indicate that the
battery is not functioning, and needs replacement. Order
the battery through Baltimore Parts (P/N 333Q0001786)
or purchase at most electronic shops (manufacturers P/N
CR-2032).
