address to locate and communicate with each sign, but signs on the same network
cannot have the same address.
Signal Converter:
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 though serial cable.

Module Numbering Example – 24x160 Front
To fully understand some Daktronics drawings, such
as schematics, it is necessary to know how various
components are labeled in those drawings. This
information is also useful when trying to
communicate maintenance or troubleshooting
efforts.
Figure 7:
Module Numbering
A module is the building block of the Galaxy sign.
Each module measures 8 pixels high by 16 pixels
wide. By placing modules side-by-side and on top of
one another, a sign of any size can be designed and
built. Individual modules can be easily removed
from the sign if required.
Figure 6
above illustrates
how Daktronics numbers modules on a Galaxy sign.
Figure 7
on the right breaks down the module
numbering method.
The label “A” on a drawing typically denotes an assembly. An assembly can be a
single circuit board or a collection of components that function together, usually
mounted on a single plate or in a single enclosure. Assemblies are divided into two
types: those that route signal and those that route power.
