Serial Port: An actual serial port is required for direct connections from the
computer or those through a signal converter. Certain USB adapters create an
“actual” serial port and others create “virtual” ports. The Venus 1500 software will
not recognize a virtual port; therefore use of a USB adapter is not supported by
Daktronics.
Serial Server: Device used to obtain information from a
LAN and convert it to a serial signal. The communication
protocol used is called TCP/IP.

Sign Address: Identification number assigned to each sign
of a network. Flipping DIP switches on the controller sets the
sign address. The control software uses the address to locate
and communicate with each sign, but signs on the same
network cannot have the same address.
Signal Cable Tester: Used to test the cable connections and
data communications through an RJ11 jack.
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 a
straight though serial cable. The RS232 to RS422 signal
converter is shown in
Figure 4 .
1.5 Daktronics Nomenclature
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 5: Module Numbering Example – 48x160 Front
A module is the building block of the Galaxy sign. Each
module measures 16 pixels high by 32 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 5 illustrates how Daktronics numbers
modules on a Galaxy sign. Figure 6 breaks down the
module numbering method.
