How to Use This Manual

This manual explains the installation, operation, maintenance, and troubleshooting of

the SI-32 (Switch Interface - 32 Input). For questions regarding the safety, installation,

operation, or service of this system, please refer to the telephone numbers listed on the

cover page of this manual.

Important Safeguards:

1. Read and understand these instructions before installing.

2. Do not drop the SI-32 or allow it to get wet.

3. Be sure the display is properly grounded.

4. Disconnect power to the sign when it is not in use.

5. Disconnect power when servicing the sign.

The manual contains ve sections: Introduction, Mechanical and Electrical Installation,

Operation, Maintenance and Troubleshooting, and Reference Drawings.

• Introduction covers the basic information needed to make the most of the rest

of this manual. Take time to read the entire introduction as it denes terms and

explains concepts used throughout the manual.

• Mechanical and Electrical Installation provides general guidance on terminating

power and signal cable at the sign.

• Operation provides general information on using the Venus®1500 Software with

the Switch Interface, and the type of switch modes.

• Maintenance and Troubleshooting addresses such topics as care of the unit,

troubleshooting the unit, and performing general maintenance.

• Reference Drawings includes the drawings referenced in this manual.

Daktronics identies manuals by the ED or DD number located on the cover page of

each manual. For example, this manual is referred to as ED-10606.

Figure 1 illustrates Daktronics’ drawing numbering system. This number is located in the

lower-right corner of the drawing. The manual refers to drawings by listing the last ve

digits and the letter preceding them. In the example below, the drawing would be

referred to as DWG-069945.

Introduction

Product Description

The SI-32 is a 32 input message selector for Daktronics DataTracTM and Galaxy®displays.

This unit provides 32 optically isolated inputs. Two SI-32 units can be chained together to

provide for a total of 60 isolated inputs.

The 32 input switch interface (SI-32) controls what preprogrammed messages, created

using the Venus®1500 Software, appear on the display. These messages must exist at

the display for the SI-32 to run them. Refer to the proper display manual for questions

regarding the display. Refer to the Venus®1500 Software Manual for information on

message editing.

Denitions

BCD: A BCD (Binary Coded Decimal) is a switch with multiple contacts. When a number is

selected, the corresponding BCD combination of contacts is closed.

Momentary: Momentary is a type of switch with two terminals and one movable contact.

When the switch is depressed, the contact closes the two terminals. When the switch is

released, the contact opens the two terminals

Network: A network consists of multiple displays connected to each other. Up to 240

Venus®1500 controlled displays can exist on one network.

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).

Sign Address: The sign address is an identication number assigned to each sign of a

network. The Venus®1500 Software uses the address to locate and communicate with

each display. Signs on the same network cannot use the same address.

SPDT: A SPDT (Single Pole, Double Throw) is a type of switch action found on many types

of switches. A SPDT switch has three (3) terminals and one movable contact that make a

connection between two (2) terminals at a time. A SPDT switch controls two circuits.

Introduction

SPST: A SPST (Single Pole, Single Throw) is a type of switch action found on many types

of switches. A SPST switch has two (2) terminals and one movable contact that make a

connection between terminals when switched on. A SPST switch controls one circuit.

Venus®1500 Version 3 Software: The Venus®1500 Version 3 Software is a Daktronics

designed, Windows®based software used to make and edit display messages. The

Venus®1500 operating Version 3 software requires Windows®98, NT 4.0, Windows®2000, or

Windows®XP Home/Professional with the most current updates installed.

Venus®1500 Version 4 Software: The Venus®1500 Version 4 Software is a Daktronics

designed, Windows®based software used to make and edit display messages. The

Venus®1500 operating Version 4 software requires Windows®XP Home/Professional,

Windows®Vista™, or Windows®7 with the most current updates installed.

Mechanical Installation

The switch interface should be

mounted near the operator. It

can be placed on a desktop

or hung from a wall nearby.

Refer to Figure 3 for the

mounting hole conguration

on the back of the interface.

Computer to SI-32

Connections

RS232 System

A RS232 system connects the

SI-32 directly to the computer

with an adapter.

1. Plug the 9-pin or 25-

pin DB to RJ11 adaptor

(depending on your PC) to

the PC’s RS232 serial COM

port.

2. Plug one end of the phone cable into the adapter and the opposite end into the

“RS232 IN” jack on the SI-32.

3. Indoor Displays: Use a ipped 24 AWG phone cable to connect the display to the

RS422 output (J3).

Figure 3: Switch Interface Mounting Hole Locations

Mechanical and Electrical Installation

4. Outdoor displays: Use a 6-conductor cable from the SI-32 (TB9) to the RS422 IN at the

display. The signal cable will be wired one-to-one from the SI-32 to the display input.

(See your display installation manual for RS422 input location.)

5. Connect additional displays as described in the display’s installation manual.

RS422 System

A RS422 system requires a signal converter to connect the SI-32 to the computer. This

provides up to 4000 feet between the SI-32 and the computer.

1. Plug the serial cable’s DB25 pin connector into the signal converter.

2. Plug the DB9 connector into the RS232 COM port being used. If your computer has a

DB25, use the DB9 to DB25 adaptor.

3. Plug the signal converter’s power cord into a 120 VAC grounded outlet.

4. Plug a ipped phone cable into the “RS422 OUT” (J2) of the signal converter and the

opposite end into the “RS422 IN” (J2) of the SI-32.

5. Indoor Displays: Use a ipped 24 AWG phone cable to connect the display to the

RS422 output (J3).

Mechanical and Electrical Installation

6. Outdoor displays: Use a 6-conductor cable from the SI-32 (TB9) to the RS422 IN at the

display. The signal cable will be wired one-to-one from the SI-32 to the display input.

(See your display installation manual for RS422 input location.)

7. Connect additional displays per your display’s installation manual.

Switches to SI-32

The switches are NOT supplied by Daktronics.

Note: Each switch input has a P and an N connection, which are connected to an

internal +5V and ground respectively.

Note: Set the DIP switch to the correct setting before powering up the switch

interface. The switch setting is only recognized on boot-up. If you change the

switch setting, recycle power to the unit.

SPST

Each SPST switch connects to

one switch input and controls

one message. Refer to the OSI-

32 Wiring Diagram.

1. Connect one N.O.

(Normally Open) terminal

of the SPST switch to SW1-P

and connect the other C

(Closed) terminal to SW1-N

as shown in Figure 6.

2. Connect all other SPST

switches per Step 1.
