System Overview
2.1. General - SLCD43 controller
The SLCD43 plus attached LCD touch panel acts as a "smart terminal" and is generally
connected to a "host" processor that implements the desired Graphical User Interface
(GUI). The host can be any kind of processor from an eight bit microcontroller to a PC.
The host issues commands to the SLCD43 and receives button press responses from the
SLCD43. In this manual, the term "host" is used to describe the device connected to the
SLCD43.
Note that the SLCD43 board can also work with panels that do not have a touch screen. In
this case, the touch-related commands are not used.
The SLCD43 board contains flash memory that is used for bitmap and macro storage. (This
is sometimes referred to as “external” flash to distinguish it from the processor’s internal
flash memory that stores the SLCD43 processor firmware.) A bitmap is equivalent to a
Windows ™ bitmap file – it is a rectangular image. Bitmaps, the BMPload program used
to store these into the SLCD43, and macros which are a stored command sequence are all
described in the SLCD Command Reference Manual.
The SLCD43 is connected to the host processor via a serial port. The SLCD43 has 3
separate serial ports plus a USB/Serial device port. There are several reasons for having
multiple ports:
a) Host program development and debugging. One port is connected to the host and
another to a PC. The PC is used to download images and macros that the host uses.
The two ports allow both the host and PC to be connected without having to switch
cables. The PC can also be used for interactive command execution / testing.
b) The SLCD43 supports serial pass-through via the "aout" and "ain" commands. This
allows serial peripherals to be attached to the SLCD43 and accessed by the host. This
is useful for systems where all serial ports are in use and an existing serial-attached
device can be moved over to an SLCD43 serial port.

2.2. LED indicators
The SLCD43 board has three LEDs to indicate operational status.
D1 shows USB activity (not present on SLCD43P).
D2 is lit while the SLCD43 is executing a command or running a looping macro. It is
useful to determine the activity level of the SLCD
D3 turns on when power is applied and the microcontroller is operating correctly. It can
also be turned off and on via the SET LED command.

Configuration Guide
3.1. Power
The SLCD43 requires 5VDC power. See Section 4 for connector pinouts. Power is applied
to connector J2 which also contains the COM0 serial interface.
3.2. Serial
The SLCD43 has four serial ports. Any of them can be used to send commands to the
board.
The physical interface options are as follows:
COM0 - RS232 (or factory option for 3.3V CMOS levels).
COM1 - 3.3V CMOS level signaling with RTS handshaking for an external
transceiver such as RS485.
COM2 - 3.3V CMOS level signaling (Revision B board only).
COM3 - USB (looks like a serial port to the host PC) (SLCD43, SLCD43H)
TTL-level (SLCD43P only)
By default, all serial communications is 115200 baud, 8 data bits, no parity, with 1 stop bit,
and receive flow control via XON / XOFF. This can be changed by using a “power-on
macro” which is described in the Command Reference manual.
3.3. TFT Panel Orientation
The SLCD43 firmware is available in landscape or portrait modes. The ordering part
number contains the firmware revision, which specifies the orientation.
3.4. Grounding
The SLCD43 mounting holes are connected to digital ground. These must also be
connected to Chassis ground either directly or through a transient protection diode for
ESD. The touch circuit has ESD protection that shorts ESD on the touch panel to board
mounting hole ground.

SLCD43 Development Kits
The SLCD43 is available in a development kit form that includes a "production module"
(SLCD43 board plus attached display and touch screen). The kit comes pre-loaded with
bitmaps and macros that implement a demo. The demo runs if the unit is powered on with
the main communications port looped back transmit to receive. This loopback is affected
via a jumper on the "PowerCom4" board. The demo macro is #1. See the SLCD Command
Reference Manual for information on macros.
The SLCD43 board in the development kit has panel-specific hardware and firmware
options loaded. In general, it is not advised to use a Development kit board to drive a
different panel. Though it seems like this should not be an issue if the connectors look like
they match, there are many details that can cause a panel not to work. Unfortunately there
is no standard pinout for these panels, even when the connectors have the same number of
pins.
The development kit includes a two-port DB9 interface board (the PowerCom4) that makes
it easier to set up a development environment. One port can be used to download bitmaps
from a PC while the other connects to the "host" computer. The SLCD43 and SLCD43H
boards also have a USB device port that can be used to connect it to a PC. The SLCD43P
has a TTL UART port that can be used with Reach’s USB-TTL cable (P/N 23-0177-72) for
the same purpose.

6.1. Getting Started
The SLCD43 kit as shipped contains a demo that allows you to verify its functionality.
Plug the supplied power supply into the barrel connector on the triangular shaped
PowerCom4 board. The display should light up and lead you through various touchactivated screens.
Note that the demo is pre-loaded into the flash memory, and includes both bitmap files and
a macro file. To best learn how the SLCD43 board and this kit works, start with simple
commands using the serial interface and leave the creation and use of macros for later.
Appendix G of the SLCD Command Reference manual provides a short tutorial.
A video tutorial on using the SLCD43 kit, called “Getting a Development Kit Up and
Running”, can be found on the Reach Web site www.reachtech.com. Click on the
“Tutorials” link in the “Support” section of the left-hand navigation bar.
6.2. Connecting the kit to a PC - Serial or USB
The kit should be connected to a PC so that the serial command interface can be
experimented with. This is a preliminary step before the unit is connected to the embedded
system that will control the display in the embedded system. PLEASE NOTE: In order
to communicate over the main serial port, the Demo jumper JP1 on the
PowerCom4 board must be removed. This jumper loops back transmit to receive on the
serial port and this is what tells the display to run the demo.
The SLCD43 or SLCD43H can be powered entirely through the USB port (J3). Before
using the USB port, download and install the VCOM (Virtual COM port) drivers from
FTDI here. The chip on the SLCD43 and the SLCD43H is the FT232R. The driver should
be installed before the USB port is plugged into the PC.
The SLCD43P can be powered entirely through the TTL UART port (J3) using Reach’s
USB-TTL cable (P/N 23-0177-72). Before using the USB cable, download and install the
VCOM (Virtual COM port) drivers from FTDI here. The driver should be installed before
the USB port is plugged into the PC.
As shipped, all serial ports including USB are set to 115,200 baud, 8 bit, 1 start, 1 stop, no
parity. Connect the PC using a straight through cable to the DB9 marked "MAIN" (P1). If
the PC does not have a serial port, use the SLCD43 USB port.
A USB-to-serial adapter cable can also be used. Note: the Belkin USB-serial adapter has
software compatibility issues and is not recommended; Reach recommends either
Prolific or FTDI chip based adapters.
SLCD43 Controller Manual V1.27
09/14/2015
Page 26
Once connected, use a terminal emulator such as Tera Term or RealTerm to send and
receive commands from the kit. Tera Term is able to run macros which can simulate the
user interface on the SLCD43 using a PC. The old Windows ™ terminal emulator,
HyperTerminal, has limitations that can cause problems; specifically, some versions cannot
send the "escape" character.
6.3. Developing the application GUI with an embedded controller as host
To develop the host-driven GUI, connect the SLCD43 main port to the host and any of the
other ports to a PC. This way either the host or the PC can drive the SLCD. Typically the
PC is used to experiment and determine what command is needed for a graphical element,
and to download new bitmaps and macros without having to disconnect the embedded
system.
The SLCD43 has a console "auto-switch" feature that allows any serial port to be used as
the main control port. Only one SLCD43 port is the active or "main" port at any time.
However, when any other port receives three <return> characters in a row, it auto switches
to become the main port. This way, the PC can take control of the SLCD43
communications channel and send commands or download new bitmaps. The reset button,
*RESET command, or a power cycle restores the previously active main port.
[Note: the *prevCons command will also restore the previously active main port. Also, the
control port autoswitch character is <return> by default but can be set to a different value
with the *auxEsc command. See the SLCD Command Reference Manual]
The SLCD43 has non-volatile memory which remembers which port is the “main” control
port. This allows any of the SLCD43 serial/USB/TTL ports to be the main port on poweron. See the SET CONTROL PORT command in the Software Reference Manual.

6.7. Kit / PowerCom4 Operational Notes
1. The unit default baud rate is 115200. The unit does not echo characters (for
communications efficiency), so you must select "echo characters locally" or "half
duplex" in your PC communications program. Also, all return strings are terminated
by a <return> only, so you need to specify “add line feed to line return” as well.
2. The demo requires a certain set of bitmaps to be loaded. These are loaded as part of
the kit. If these are not present, it will not run correctly. Copies of these are provided
in the "BMPs and Macros" directory on the CD provided, or on the Reach Download
Center. Use the BMPload program and load the demo.lst and macros.mac files to
restore the demo.
3. The SW1 “RESET” button on the PowerCom4 board resets the SLCD43 processor
and performs the equivalent of a power-on reset.
4. The SW2 "SELECT” button on the PowerCom4 board is intended for use with kits
that don't have a touch screen, and is not implemented on a standard kit.
5. Jumper JP1 on the PowerCom4 board is the “DEMO” serial loopback jumper that is
installed at the factory in order to automatically run the demo at power up. Remove
the jumper prior to attempting serial communications with SLCD43 controller.
6. The J1 barrel connector on the PowerCom4 board is the external power supply
connector for the development kit. With the SLCD43, the power supply is 5VDC
input and the barrel connector is 2.5mm center pin positive.
7. PowerCom4 connector J2 provides the communications path for the P1 “MAIN”
RS232 serial port. It connects to J2 of the SLCD43 controller via cable 23-0064. This
connection also provides 5VDC power to the SLCD43 controller.
8. Connector J3 of the PowerCom4 board is the communications path for the P2 “AUX”
RS232 serial port. It connects to J1 of the SLCD43 controller via the 23-0101 cable.
This provides the path for the “RESET”, and “SELECT” signal buttons. As well as
the communications path for downloading of bitmaps and macros to the SLCD43
controller.
9. Connector J4 on the PowerCom4 board is reserved for future use.

Touch unreliable or non-operative
If the touch screen is unreliable or non-operative, do the following:
1.
Run the TOUCH CALIBRATE command, "tc". This will reset the calibration
values and allow you to recalibrate the touch screen.
2.
If after doing this the touch is still non-operative, check the cable connection into
the SLCD43 board.
To determine the accuracy and sensitivity of the touch, you can use the "debug"
command as follows:
*debug 1<return>
This puts an "X" on the screen whenever a valid touch is recognized. To turn off, use:
*debug 0<return>

Appendix D – 3.3V CMOS UART Interface
It is generally recommended that the RS232 interface be used to communicate with the
SLCD43. The advantages are the ability to remote the display from the host, and easier
debugging by spying on the RS232 interface. However, in retrofit situations, an RS232
port may not be available.
There are two options to connect to the SLCD43 via UART at 3.3V CMOS levels.
D.1 COM2 via J4
The connector J4 has power, ground, reset-, and UART TxD and RxD. This is the easiest
way to connect at 3.3V CMOS levels. The BMPload program can be used to set COM2 as
the active main port.
D.2 COM0 via J2 (SLCD43, SLCD43H)
The SLCD43 and SLCD43H serial port COM0 is typically used for communication using
RS232 levels. However, by removing resistor R17, it can use 3.3V CMOS logic levels.
This is typically a factory option, but the user may make this change as needed. R17 is
located under U2 which is under connector J2.
COM0 Logic Level Mode:
1. Resistor R17 (below U2) must be removed.
With R17 removed, connector J2 must be wired for Logic Level Mode:

D.2 COM0 via J2 (SLCD43P)
The SLCD43P serial port COM0 is typically used for communication using RS232 levels.
Circuitry on the connector auto-detects the presence of a valid RS232 input signal, and
switches to RS322 voltage levels on pins 3 and 4. R17 is not used. By using the wiring
pinout shown below, it will use 3.3V CMOS logic levels on pins 1 and 2 instead. No
hardware modification is required.

Appendix E – Battery Operation Options
E.1 Running the backlight directly from the battery
When the SLCD43 is used with a battery supplying the power, efficiency is important for
long battery life. The largest power drain when operating is the backlight. Driving the
backlight directly from the battery without going through a DC-DC converter can help.
(This assumes a max battery voltage of under 10V). To do this:
1.
2.
Remove resistor R33 that shorts J2 pin 5 and J2 pin 7
Supply 3.3-10V from the battery to J2 pin 5. This directly drives the
backlight up-converter.

E.2 Running the board from 3.3V instead of 5V
The SLCD43 generates its own 3.3V supply via a linear regulator. Powering the board with
3.3V will save 1.7/5 = 34% power compared to 5V. To do this, the LDO is shorted and the
diode that allows the unit to be powered from the USB port (5V) is removed. Once this
change has been made, the board cannot be powered from the USB port.
To do this:
1.
2.
3.
Add zero ohm resistor, size 0805 to location R12
Remove diode D6
Supply 3.3V to J2-7 instead of 5V.
Contact Reach for other power saving options.
