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).
E4
No Message Error: This code is
shown when there are no
messages 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 all address switches are
“OFF”. (Note: in some older
drivers this happens when no
address plug is installed in J19.)
Set the line number by setting the
binary address on S1 (or installing
the correct plug in J19). The
Protocol 4 plug designates this
driver as the “host.” If this is not the
host, remove the Protocol 4 plug
from J20.
Power On Self-Test:
A useful troubleshooting tool is the power on self-test the host driver performs every
time it powers up:
• If the signal wiring between each controller is correct, the first two digits of
each driver will display “Ad” momentarily, and the first digit will then flash
three numbers indicating the decimal address that is set with the address
plug in J19. (If a client driver displays “A
“P
• self-test.)
• Next, the first two digits of each line will display “Lx”, where “x” is the line
number that the driver is set to control (set with address plug).
• Finally, each line will display “1234…” according to the column number of
each of its digits. Every line should show “1” on the left-most digit, and all
digits should be numbered consecutively from left to right. If this is not the
case, either the wrong address plug is installed, or the driver or digit harness
is connected incorrectly.
If there is no address set (or address plug installed) on the host driver, the host driver
will display “E5,” and all client drivers will continually cycle through the power on
self-test.
