Description
DANGER
Indicates the presence of an extreme hazard that will cause death or severe personal

WARNING
Indicates the presence of a hazard that can cause death or severe personal injury.
Hazards of this kind MUST be avoided.
CAUTION
Indicates the presence of a hazard that can or will cause minor personal injury or

Safety Summary and Cautions Concerning Servicing the Unit
The information that follows applies to general safety precautions and may not be reiterated elsewhere in
this manual.
WARNING: Risk of Electric Shock.
Whenever possible or applicable, remove the cable from the negative terminal of vehicle’s
battery or power source first and then remove the cable from the positive terminal before
performing any installation or service procedure. Only trained service personnel should
perform the procedures outlined in this maintenance manual. These procedures may allow
exposure to high electrical energy that could result in electric shock and injury to
untrained personnel during servicing, maintenance, and installation of the unit.
Never perform maintenance or service to equipment with the power turned on. Always
remove the power first. To avoid personal injury, always remove power from the
equipment prior to performing any procedure. Circuits should also be discharged and
grounded before beginning service procedures. Always work with another person who can
render aid in the event of an accident.
CAUTION: Components is this system may be potentially damaged by electrostatic
discharge. Always use a wrist grounding strap and/or a grounded antistatic floor mat when
servicing the equipment.
All components that may be susceptible to damage by electrostatic discharge should be
stored in suitable antistatic bags or other suitable containers.
In case of welding operations using welding systems with electrodes and other operations
that may result in rapid battery discharge and recharge, the Standard Sign System MUST
be disconnected from the power supply before any work is performed.

Maintenance Related Guidelines
Signs and the Central Control Units (CCUs) are made of components that normally do not require
maintenance. During the installation phase of the system Aesys recommends that the mounting hardware
used for the support stirrups include properly fitting washers that will not accidentally loosen and that the
housing where the sign is located has enough ventilation to avoid the excessive accumulation of heat (for
auto-heating solar light radiation heating).
Periodically verify the state of the stirrups and the tightness of the mounting screws, especially for the
parts exposed to direct user contact.
Signs do not produce dangerous voltages internally and use voltages that are less than the vehicle’s
power supply voltages. In case of a damaged connector or connection cable or of accidental contact with
external parts (the housing), the voltage is short-circuited to ground causing protection hazards.
We recommend that the user contact Aesys personnel if any anomalies with the display (sign) occur.
Aesys cannot be responsible in the case of display system intervention by unauthorized personnel.
In the case of substitution of the internal circuit boards or spare parts, we recommend that the user refer
to the electrical diagrams that are included later in this maintenance manual.
Firmware and Manual Versions and Revisions
Firmware Versions
The user can establish their current firmware version and a copy of the maintenance manual that was

Manual Versions
Referring to Figure 1 that follows, the front cover page of the Standard Sign System Maintenance Manual
is clearly marked with its publication number as well as information about its version number and
approximate date of publication. The inside cover page also includes this information as does every page
in the manual.
When troubleshooting a problem that may occur, Aesys Customer Service and Support Personnel may
ask for this information in order to ensure that the user is referencing the proper version of the manual.
Figure 1 —Manual Version Information
Firmware and Manual Versions and Revisions
It is important to note that there is no direct correlation between the versions of both firmware and the
maintenance manual. For example, at the time of this writing, the latest version of the Standard Sign
System Maintenance Manual was Version 1.0 and the CCU firmware was Version D7A10A.1.
Aesys Customer Service and Support Personnel have the necessary information needed to establish
whether your version of the maintenance manual is appropriate for the firmware version you are using.
Change Management
In the future Aesys, Inc. may offer future enhancements and changes to the Standard Sign System by
releasing new firmware versions. If this occurs, existing Standard Sign System users will be offered the
opportunity to update their software or firmware.

System Overview
Introduction to the Standard Sign System
The full color Light Emitting Diode (LED) Standard Sign System is a high performance product with
optimized visibility characteristics. It is designed to display destination, public relations information, and
general messages that can be controlled manually by the KC640 on-board Central Control Unit (CCU).
Each bus is equipped with a CCU and a number of signs. In typical applications, these signs include a
front sign, dash sign, route side sign, and a side sign that are controlled by manually entering code
numbers on the CCU. The system is built using solid-state components to ensure long life and low
maintenance. Figure 2 shows the Standard Sign System General System Diagram. The system is usually
composed of the following components in each installation (per bus):
KC640 Central Control Unit with microprocessor (This is the central element that manages all
system components.)
Display panels (signs) mentioned above
Data/Power circuit wiring harness, and
Power supply wiring harnesses.
Depending upon the unique design configuration of a bus, the Standard Sign System can have a different
number of signs. Therefore, Figure 2 is representative of a general system only. All components in the
system operate on 12 V DC OR 24 V DC. Any power fluctuations within 10 percent will not normally have
an effect on the system. However, wider fluctuations must NOT continue for extended time periods,
because this may result in blowing an internal fuse or possibly component failure.

Chapter 3 —
KC640 CCU Operation
Introduction
The KC640 Central Control Unit (CCU) is the Aesys on-board controller device. Its primary function is to
transmit messages and/or destinations to the destination sign system. It is responsible for the
management of all communications with associated signs and provides a user-friendly interface. A front
view of the CCU is shown in Figure 3.
Figure 3 —KC640 Central Control Unit
Functionally, it is the on-board device for selecting the line code and/or the destination of the vehicle.
Once a selection has been made, the CCU will start to transmit in three seconds, sending the destination
information to the LED display panels (signs). The CCU also monitors system operation and provides the
user with important diagnostic information.
The operator can use the CCU’s LCD to verify that the destination message or code number selected
with the keyboard is the one he wishes to display, before sending the command to actually display the
message. It is also used in maintenance procedures to verify communication errors (Status 2). It is also
used for troubleshooting.
Basic components of the user interface include an alphanumeric keyboard, to select functions, and an
LCD display to receive confirmation of performed operations. Signals sent by the CCU are accompanied
by audible alert (beep).
The KC640 CCU is normally supplied complete with operational firmware and a customer database (TRX
file) containing the information to be displayed on the signs. Both functional firmware and customer
database information can be updated using a SmartMedia1card. A special port for reading SmartMedia
cards is located on the right side of the CCU (see Figure 8 on Page 19).

KC640 Central Control Unit (CCU) Features
The major controls on the KC640 CCU are detailed below in Figure 4.
Figure 4 —KC640 Central Control Unit, Selected Features I
The CCU command system using the keyboard can be divided into two levels. The first level is for normal
viewing and is the default screen. The second level is for CCU set-up.
In the first level the controls for normal display/default screen are as follows:
<F1> —Press to switch to second level (CCU set-up)
<F2> —Mode selection (internal message) ―Disabled‖
<F3> —Press to set route (line) code ―Disabled‖
<F4> —Press to set a public relation (P/R) message
<F5> —Press to set destination ―A‖
<F6> —Press to set destination ―B‖
<ENT> —Panel information refresh (confirm performed selection), and
