Daktronics DataTime Outdoor LED Time & Temperature Displays - Manual (Page 23)

Error Codes
Some DataTime displays have their own built-in troubleshooting mechanism. Failures that
may occur in the display driver are described using codes. In the event a display
malfunctions, a failure code registers by showing an “Ex” value on the first two digits of the
display. “E” simply indicates an error, and the letter “x” represents the actual code number.
Refer to the following table for a description of each failure code and for possible solutions.
Note: The LCD screen on the DataMaster 100 controller will not show the failure codes
described in the table below. Failure codes will only be shown on the DataTime display.
Failure Code Description Possible Solution
E1 Protocol Setting Error: There is an
unsupported driver protocol setting.
Check the value set in the protocol
plug of the driver (J20).
E2 Time Error: No valid time is stored
in the driver; it may be a failure of
the real-time clock on board or other
timekeeping device.
Set the time in the display using
the Set Time menu option on the
DataMaster 100 controller.
E3 Temperature Error: No response
coming from the temperature
sensor, or general temperature
sensor failure.
Check the temperature sensor
location and verify all connections.
Refer to Section 2: for wiring
information.
Note: The temperature sensor
takes approximately 10 seconds to
initialize on power-up. The display
will show this error until
initialization is complete.
If a temperature sensor is not
used, set the hold time to zero.
E4 No Message Error: This code is
shown when no messages are
downloaded to the display
Download a new message to the
display using the <DISPLAY
SEQUENCE> key on the
DataMaster 100 controller.
E5 No Line Number Selected Error:
The driver for this line has a
Protocol-4 plug installed in J20, but
the address is not set on the
address switch.
Set the line number by setting the
address using the address switch.
The Protocol-4 plug designates this
driver as the “host.” If this is not the
host, remove the Protocol-4 plug
from J20.
