2 Introduction
Section 1: Introduction
1.1 How to Use This Manual
This manual explains the installation, maintenance, and troubleshooting of VF-2300 series
Dynamic Message Signs (DMS). For information regarding the safety, installation, operation,
or service of this system, refer to the telephone numbers on the cover page of this manual.
Daktronics identifies manuals by the ED or DD number located on the cover page of each
manual. For example, this manual is referred to as DD3891099.
The serial and model numbers for the display are on the ID label attached to the display. This
label looks similar to Figure 1. When calling Daktronics Customer Service, please have this
information available to ensure timely response.
Daktronics builds displays for long life, and they require little maintenance. However, from
time to time, certain components need replacing. Refer to the Daktronics Exchange and
Repair & Return Programs in Section 6.2 if any component needs replacement or repair.
1.2 DMS Overview
The VF-2300 series displays are front access.
1.3 Theory of Operation
Vanguard®Software
Daktronics Vanguard®software allows the DMS operator to check display status and to
control messages. Refer to the Vanguard®Software Help File for information about
operating Vanguard®software.
VFC-3000 Controller
The VFC-3000 controller is the communication hub for DMS management; it is located in the
display or in the traffic cabinet.
Figure 1: Display ID Label

Introduction 3
The central controller creates messages and transmits them to the VFC-3000 controller for
storage. Upon request from the central controller or the front panel interface, the VFC-3000
controller locates the message to display and sends it to the display’s modules via the
distribution board. The modules activate the appropriate pixels to form the message.
The VFC-3000 controller also monitors local sensors (display-based sensors) like temperature,
light level, and door detection. The VFC-3000 controller interprets sensor data for display
control and diagnostic functions, such as adjusting the display’s intensity for current lighting
conditions.
1.4 Auxiliary Control Panel (Optional)
The auxiliary control panel (ACP) complements the VFC-3000 controller by providing a
secondary control interface panel at the DMS site. The ACP allows a maintenance technician
to perform diagnostics while working in one location without having to access the VFC-3000
controller in another location. This improves safety and reduces maintenance time.
1.5 Display Peripherals
A peripheral is a display component configured through the VFC-3000 controller. Peripherals
include sensors, power supplies, low voltage distribution boards (LVDB), fans, and heaters.
