TOUCH SCREEN LCD MODULE HANDLING PRECAUTIONS
The following precautions will guide you in handling of our product correctly:
1.
Liquid crystal display devices:
1.1. The liquid crystal display device panel used in the liquid
crystal display module is made of plate glass. Avoid
any strong mechanical shock on LCD and touch screen.
Should the glass break, handle it with care.
1.2. The polarizer adhering to the surface of the LCD is
made of a soft material. Guard against scratching it.
1.3. Wash your hands or clothes if you touch liquid crystal!
2.
Avoid Static electricity!
2.1. When working with the module, use your naked or gloved hand and wear nonconductive work suit to prevent generating static electricity by friction. ESD ground
straps should be utilized.
2.2. Be sure to ground any electrical appliances you may be using, such as soldering
iron, cutting pliers, tweezers, etc.
2.3. Floors, doors, and work tables must be grounded to discharge electricity.
3.
When the LCD module alone must be stored for long periods of time:
3.1. Protect the modules from high temperature and humidity.
3.2. Keep the modules out of direct sunlight or direct exposure to ultraviolet rays.
3.3. Protect the modules from excessive external forces.
4.
Use the module with a power supply that is equipped with an over current protector
circuit, since the module is not provided with this protective feature.
5.
Do not ingest the LCD fluid itself should it leak out of a damaged LCD module. Should
hands or clothing come in contact with LCD fluid, wash immediately with soap.
6.
Conductivity is not guaranteed for models that use metal holders where solder
connections between the metal holder and the PCB are not used.
7.
Do not stack up modules since they can be damaged by components on neighboring
modules.
8.
Do not place heavy objects on top of the product. This could cause glass breakage.
9.
Do not scratch LCD or touch screen!
10. In order to maintain module reliability, do not touch or hold by the connector area.
11. Avoid any bending, pulling, or other excessive force on flexible cables, which can result
in broken connections.

1. FUNCTIONS AND STRUCTURE
1.1. GENERAL
The TC55149S is an intelligent LCD controller with an integrated touch screen control that
supports Kyocera Display (former Optrex) T-55149 240x400 TFT Transflective Graphic
LCDs. This controller allows user to individually control each display pixel. This independent
pixel control allows user displaying both text and graphics simultaneously. The TC55149S
utilizes AT32UC3B0256 microcontroller and external 64Mbit serial flash. The device can be
used as an “intelligent” LCD controller or as stand-alone controller. There is enough of flash
and RAM memory in the controller on board to incorporate additional graphical commands
or to customize the firmware for particular tasks.
1.2. FEATURES
1.2.1. Serial (RS-232 or USB) communication interface with seven
programmable baud rates
The serial parameters for communication between the TC55149S controller and
the host are as follows:
Baud Rate: 9600, 14400, 19200, 28800, 38400, 57600 or 115200 bps (default)
Parity: None
Data Bits: 8
Stop Bits: 1
1.2.2. 64Mbit external flash memory
TC55149S has 64Mbit of flash memory for fonts, bitmaps and images storage.
The external flash memory is capable to save up to 43 (240x400) screen
images. A utility program allows user to save 240x400 pixels *.bmp, *.jpg and
*.gif patterns to memory.
1.2.3. Voltage regulator
The TC55149S has a built-in voltage regulator with input 5-15 VDC, connector
J8 or J7 optional. 3.3V power may be applied to J10 eliminating the need for an
onboard voltage regulator.
1.2.4. Touch screen controller
The TC55149S controller utilizes the AD7147 CapTouch™ controller and allows
touch screen to operate as a multi-touch keypad by sending pressed keypad ids
to host microprocessor or PC. The touch screen is divided into 12 rectangles.
1
1.2.5. Draw line/rectangle/circle
The TC55149S controller simplifies drawing of horizontal, vertical and skew
lines, pixels and shapes, such as rectangles and circles.
1.2.6. Fonts
The TC55149S controller supports 3 user-selectable fonts and 1 system font.
The imported font size should not exceed the maximum character size, which is
48 pixels high. Use TVI Electronics utility program to convert and save computer
fonts to the controller flash memory.
1.2.7. 180° screen rotation
The TC55149S controller allows 180° screen rotation. A screen rotation is saved
in the controller’s memory and will default after power on.
1.2.8. Portrait / landscape screen orientation
The TC55149S controller allows portrait / landscape screen orientation. A screen
orientation is saved in the controller’s memory and will default after power on.
1.2.9. Firmware update
The TC55149S controller’s firmware can be updated through the USB port.
1.3. POWER REQUIREMENTS
Power to the TC55149S is derived from the external power supply through J7, J8, J10
or J11 connectors. Voltages of 5-15VDC must be supplied through J7 or J8
connectors. Since it is regulated on the TC55149S, this input voltage does not need
to be regulated as long as it falls within this range. Voltage of 3.3VDC must be
supplied through J10 and should be regulated. Powering up the controller from J7 or
J8 will require installation of a jumper on J12. Powering up the controller from J11
(USB) will require installation of two jumpers on J12. Powering up the controller from
J10 (3.3VDC) will require installation of a jumper on J12. See Table 3-2.
Do not reverse the polarity on the power inputs. Doing so will permanently damage
the controller board and void the warranty.
Do not install J12 “USB” jumper if using external power from J7 or J8 connectors.
Doing so will permanently damage the controller board and/or PC and void the
warranty.

2. GETTING STARTED
This chapter guides you through the hardware connection, powering up the TC55149S
controller and setting up the software for initial testing.
2.1. HARDWARE CONNECTION
Carefully open the LCD connector latch J1 by pulling the brown latch upwards. Insert
the flat data cable contacts side up into the connector being sure the cable is fully
seated, push the latch back in being sure the cable is pushed all the way in.
If you have a touch screen carefully pull the latch on connector J2 out. Insert the
touch screen cable into J2 being sure it is seated, push the latch back in.
Figure 2-1: Hardware Connection
2.2. POWER UP
To power up the controller follow the instructions in paragraph 1.3. The controller will
display a power up screen#1 each time it is powered up. The power up screen can be
customized through the GUI Manager software. The factory default (0° rotation,
landscape orientation) will show TVI Electronics logo and current controller firmware
revision as shown on Default Power-Up Screen below.
Example 2-1: Default Power-Up Screen
3
2.3. QUICK START
Install the GUI Manager software on your PC. A serial connection is required between
the TC55149S controller board and PC in order to communicate with the controller.
You can use a USB to serial converter if your PC doesn’t have a serial port or
connect directly to a USB port.
Once the connection with the TC55149S controller is established launch the GUI
Manager software on your PC. Bring up Communication utility (accessed from the
“File” menu), select COM Port, Baud Rate (default 115200) and click “Connect”
button. Now you may begin using the software to evaluate the TC55149S controller
board.
For communication through the USB port, installation of the USB Communications
Device Class (CDC) driver is required before you can start evaluating the TC55149S
controller board.

3.1.1. Serial Communication
RS232 communication through J3 header requires DB9MF serial cable and DB-9
to 10 Pin IDC adapter.
This requires installation of the jumpers on J4 Pins 1,6 and 2,5 (Factory
Default).

J5 can be used as an optional RS232 connector.
Figure 3-8: PC to TC55149S Controller Connection
A serial TTL interface is supplied at J6, see Table 3-8. For TTL interface, remove
jumpers from J4 Pins 2,5 and 3,4.
3.1.2. Baud Rate Settings
The TC55149S controller has seven programmable baud rates (default is 115200
bit/sec). A baud rate is set by a command and stored in the flash memory.
3.1.3. Firmware Update
TC55149S controller supports firmware updates. The firmware can be updated
through the USB port.
3.2. TC55149S COMMANDS LIST
Upon power-up, the controller will display screen#1 and send code 0x21 (ASCII “!”)
to the host. The host controller will need to wait until it receives the 0x21 code
before sending another command to the controller. This will prevent the host from
jamming the interface and filling the command buffer and also keep the host and
LCD controller in synch.
