Daktronics DataTime Outdoor LED Time & Temperature Displays - Manual (Page 31)

Note: When reconnecting, remember
these are keyed connectors and will
attach only one way. Do not attempt
to force the connections.
5. Remove the screws, nuts, or wing
nuts securing the driver to the inside
of the enclosure.
6. Carefully lift the driver from the
display and place it on a clean, flat
surface.
7. Follow the steps in reverse order to
attach a new driver.
In the display, the LED drivers perform the
task of switching digits on and off. Refer to
Drawings A-166216 for a complete listing of
driver connecter functions and wiring pin
numbers.
DataTime Time & Temp displays use four-column drivers which have four outputs to digits.
Figure 17 identifies the connector functions
for a four-column driver. (Major functions
are the same on 16-column drivers.) The table
lists the functions of the various jacks,
including which ones are not used in this
application.
The display line controlled by the driver is
set with an eight-position DIP-switch that is
set before shipping. (Note: Some older
drivers use a 12-position address plug
inserted in J19). All DataTime displays ship
with a “Line 1” address already set.
