used to send data to the display.
For internal wireless, simply install the
antenna on the display and connect the Wireless
Data Transceiver at the data source. Use DIP
switches 7/8 to switch between internal wireless
and hard-wire/external wireless.
STEP 3 - Connect the Power
Power can be supplied to the display from an
external 12V source (battery or AC Adapter) or
from an internal battery. If power is supplied to
the display externally, connect through the 12VDC
POWER INPUT connector located on the rear of
the display. Connecting power to the display will
set the display into a power-up self-test mode. If
the power source is an internal battery, turn on
the power using the switch on the bottom of the
display.
POWER-ON SELF-TEST
When the 6860 power source is connected,
the display begins an internal self-test and and
external visual check of the display elements.
The self-test begins by stepping through each
segment of all six digits, one segment at a time
including the colon or decimal point which exist to
the right of each digit except the right-most digit.
The self-test continues by sequentially illuminating
each segment until all segments, colons, and
decimal points are on. The self-test continues by
drawing a square frame by sliding a small square
from left to right, then down and right to left. The
square then collapses and the revision level of the
code running in the microprocessor is displayed.
When the internal self-test and external visual
test is complete, [rEAdy ] scrolls in from left to
right. Lastly, the display will show all digits full
bright and minimum brightness (programatically
controlable from some PC software. Finally, the
display will blank out leaving only one or two
dim LEDs ON within the rst digit. The display
is now ready for use.
PRODUCT SET-UP
The model 6860 Large Digital Displays
are designed to hang free using the top eyelets
supplied with the display. A display stand is also
available from RaceAmerica to hang the display
at a good viewing level 40” above ground level.
STEP 1 - Congure the Display
The DIP Switches are located on the backside
of the display behind the removable cover. They
are used to match the communications format and
the display format to the data sent to the display
from the timing system or PC. To determine the
correct switch settings, read the DIP SWITCH
SETTINGS section of this manual. Switch
settings have two positions, ON and OFF. The
ON position is indicated on the DIP switch and is
active when the switch button is moved to the right
side when viewed from the back of the display.
STEP 2 - Establish the Data Interface
The Display can receive data via a hard wired
cable or an internal wireless data link. The display
receives RS232 data at 9600 baud.
An interface cable contains a RJ45 modular
connector on one end of the cable and is connected
to the display using the SERIAL PORT connector
on the back of the display. When inserting this
connector, press inward until a click is heard to
lock the cable in place. If the cable remains loose
and no click is heard, carefully bend outward the
locking tab on the RJ45 connector approximately
45 degrees from the connector body. Re-insert the
cable into the serial port until the click is heard
and the cable remains locked in place. To remove
this cable, pinch the locking tab against the body
of the RJ45 connector and pull the connector out.
Depending upon the type of timer or PC
connected to the display, the other end of the cable
may contain an RJ45 connector for RaceAmerica
timing systems. In this case, either end of the cable
can be connected to the display or the RaceAmerica
timer. If connecting to a PC or non-RaceAmerica
timer, a 9-pin D-sub or 25-pin connector will
terminate the other end of the cable and should be
inserted into the serial communications port to be
