Daktronics AF-3180-64-R,A - Manual (Page 12)

RS232: RS232 is a standard PC communication type with a maximum cable length
of 25 feet (7.62 meters)
RS422: RS422 is a standard differential communication type with a maximum cable
length of 4000 feet (1.2 kilometers)
Signal Converter: The signal converter, shown in
Figure 4 on
the right, is a Daktronics supplied unit that converts the data
from RS232 to RS422, or RS232 to fiber optic signal. The
signal converter is connected to the control PC via straight
through serial cable.

Sign Address: The sign address is an identification
number assigned to each display of a network. It is set by
rotating hex switches on the controller. The control
software uses the address to locate and communicate with
each display. Displays that are on the same network
cannot have the same address.

1.5 Daktronics Nomenclature
To fully understand some Daktronics drawings, such as schematics, it is necessary to
know how those drawings label various components. This information is also useful
when trying to communicate maintenance or troubleshooting efforts.
Figure 5: Module Numbering Example – 24x64 Front
A module is the building block of the sign.
Each module measures 8 pixels high by 4
pixels wide. By placing modules side-by-side
and on top of one another, Daktronics can
design and build signs of any size. A person
can easily remove individual modules from the
sign if required. Figure 4 above illustrates how
Daktronics numbers modules on a Galaxy
®
sign. Figure 5 on the right breaks down the
module numbering method.
