1.1 How To Use This Manual
This manual is designed to explain the installation of Daktronics InfoNet
LED displays controlled by a Venus
installation, operation or service of this system, please refer to the telephone numbers listed on
the cover page of this manual.
The box below is an illustration of Daktronics drawing numbering system. The drawing number
“7087-P08A-69945” is how Daktronics identifies individual drawings. This number is located
in the bottom right corner of the drawing. The manual will refer to drawings by the last five
digits and the letter preceding them. In the example, the drawing would be referred to as
Drawing A-69945. All drawings referred to as such will be inserted at the end of each section.

1.2 Safety Precautions
1. Read and understand these instructions before installing.
2. Be sure that the display is properly grounded.
3. Disconnect power before working on the display.
4. Do not modify the displays or attach any panels or coverings to the display without the
express written consent of Daktronics, Inc.
5. Most products are equipped with a 3-wire grounding-type plug, a plug having a third
(grounding) pin. This plug will only fit into a grounding-type power outlet. This is a
safety feature. If you are unable to insert the plug into the outlet, contact a qualified
electrician to replace your obsolete outlet. Do not defeat the purpose of the grounding-type
plug.
1.3 Network Concepts
The concept of using LED displays as a cost effective, high impact method of communication
is rapidly growing throughout many industries and businesses. The reasons for this growth are
many, but the need for additional features and complexity of multiple sign installations has
emerged, and the Daktronics display systems have been designed to meet those needs. The
common thread to most clients’ requests is a means of programming and controlling a group
of signs from a central control point. Daktronics responded by developing a powerful system
of interconnecting and controlling signs. Great care has been taken to design products that will
satisfy a wide variety of installations. Some of the design goals of these systems include the
following:
• Easy transfer of messages
• The ability to tell a sign in the network which message it should run
Introduction
1-1
• The ability to determine the status of any sign on the network
• The ability to control multiple sign technologies on the same network
All of the programming features would seem insignificant if the installation of the systems
could not be accomplished with basic tools and without technical difficulty. Daktronics
decided to use the very popular and readily available RJ-11 connector. This connector is also
used on modern home and office telephone equipment.
All that is required for signal installation is a standard six (6) conductor modular telephone
wire. Tools required for mounting the display depend on the location and size of the display.
For some installations, it may be possible to buy pre-terminated telephone cables for use with
the displays.
There are four (4) network systems available: RS/232, RS/422, modem and TCP/IP.
1.3.1 RS/232 Network
Reference Drawing: System Riser Diagram; RS/232 ......... Drawing A-91388
RS/232 (EIA/TIA-232-E) is a standard communication interface that employs a
single-ended serial transmission scheme that uses a maximum cable length of 10
meters (30 feet). This interface was designed for computer communication at short
distances. All computers have an RS/232 communications port.
1.3.2 RS/422 Network
Reference Drawing: System Riser Diagram; RS/422 ......... Drawing A-91387
RS/422 (EIA/TIA-422-B) is a standard communication interface that utilizes a
differential balanced transmission scheme which uses a typical maximum cable length
of 1.2 km (approximately 4000 feet). The main advantage to RS/422 over RS/232 is
the longer cable length that is possible. A signal converter is needed to convert the
computer’s RS/232 to RS/422.
1.3.3 Modem Network
Reference Drawing: System Riser Diagram; Modem ......... Drawing A-91386
The modem is a standard communication interface that utilizes standard phone
transmission lines. The phone company assigns each phone line a number that the
modem uses to communicate between the controller and the display.
1.3.4 TCP/IP Network
Reference Drawing: V1500 System Riser Diagram ........... Drawing A-93904
The TCP/IP protocol is an interface allowing the Ethernet network card (installed in
the operator’s computer) to communicate with the serial server via a Local Area
Network (LAN). Information for the individual displays is distributed from the serial
server’s RS/232 output.

Introduction
1.4 Display Overview
The Daktronics Indoor LED displays have been designed and manufactured for performance,
reliability, easy maintenance and long life. The displays consist of an array of LED pixels.
The configuration of the LED pixels is dependent on the family of LED displays. The
standard character is seven pixels high by five pixels wide.
A typical system consists of a Windows
®
based personal computer (PC) running Venus® 1500
software and one or more displays. The PC controls one or more multi-line displays. The
displays are offered as single-face displays, which are single-sided stand-alone units. They
can become double-faced by mounting them back-to-back with a second unit.
The Venus 1500 is a software package which runs under Windows 3.1x or Windows 95
operating systems on an IBM
®
-compatible computer. Refer to the Venus 1500 controller
manual, ED-12717, for installation and maintenance of the Venus 1500 editing station.
InfoNet multi-line displays are character-based indoor LED displays which are available in
monochrome red or tri-color (red, green and amber) characters. Daktronics offers multi-line
displays with a 2.1” character in four (4) different lengths. The InfoNet model numbers are
described as follows: G-X00-L-7xCCC-2.1
= InfoNet Line Display
G
= 100 = Indoor Monochrome Red
X00
= Number of Lines
L
= 7 rows high
7
CCC
= The number of columns long (120, 160, 200 and 240 are available)
= 2.1 Character Height

1.5 Part Definitions
Com Port: A Com Port is a connector on the back of the controller PC. The Com Port
is used to control the sign network through either a 9 or 25 pin serial
connector.
Display
Configuration: Display configuration refers to a display’s model number, address, etc. This
information will be automatically displayed when the display is powered up.
Display configuration is as follows:
1. Output Test (DDD’s)
2. Display Model Number (i.e. G-100-3-7x120-2.1)
3. Firmware Version
4. COM1 Configuration (typically V1500)
5. COM2 Configuration (either DataView
™
or RTD)
6. Line Interrupt Rate
7. Display Address--displayed in binary code (i.e. 001)
8. Sign Name
9. Modem present (only if modem is installed)
Flipped Cable: The flipped cable is a six (6) conductor phone cable. Pin 1 of connector A
connects to pin 6 of connector B.
LAN: Local Area Network
®
Introduction

Loop Back Test: The loop back test is a troubleshooting test which connects the output to the
input. Contact Daktronics customer service for this test.
Module: A module is one unit of the display.
Network: A network consists of multiple signs connected to each other. Up to 240
Venus 1500 controlled displays can exist on one network.
RS/232: RS/232 is a standard PC communication type with a maximum cable length
of 25 feet (7.62 meters).
RS/422: RS/422 is a standard differential communication type with a maximum
cable length of 4000 feet (1.2 kilometers).
RX LED: A RX LED is a LED on the signal converter which indicates if the display is
sending data back to the signal converter.
Serial Server: A serial server is a device used to obtain information off of a LAN.
Sign Address: The sign address is an identification number assigned to each sign of a
network. The control software uses the address to locate and communicate
with each display. Displays which are on the same network cannot have the
same address.
Signal
Cable Tester: The signal cable tester is used to test the cable connections and data
communication
Signal
Converter: The signal converter is a Daktronics supplied unit which converts the data
from RS/232 to RS/422. The signal converter is used in RS/422 systems.
TCP/IP: The TCP/IP (Transmission Control Protocol/Internet Protocol) is a
communications protocol used for LAN’s.
TX LED: A TX LED is a LED on the serial converter which indicates the control PC
is sending data to the display.
Venus 1500: The Venus 1500 is a Daktronics designed, Windows based software used to
run the displays.
