Keyboard Interface

Both variants (with and without touch screen) of each series use the same key codes. If USB

is selected as keyboard interface the keyboard sends standard HID codes according to the

corresponding table of each series. If serial communication is selected the same hex-values are

sent for the single keys. For serial communication a special protocol is defined

(see section “Serial Interface”).

USB Interface

The keyboard is a standard HID device and

is configured with two interfaces

(keyboard and LED).

LED report descriptor:

The LED report consists of two bytes. The single LED’s of the keyboard can be controlled

using the assignment of Table 3. Setting a bit to “1” turns the corresponding LED on.

Otherwise setting a bit to “0” turns the LED off.

Serial Interface

Port settings

To communicate via serial interface, the following settings must be used for the Host COM

port:

 38.400 bytes/s

 8 data bytes

 1 stop bit

 no parity

RS232 protocol

For the implementation of a serial connection between the host and keyboard, the

information of the keyboard protocol is necessary. First, an overview of commands is given.

Subsequently, the structure of the data frames and control sequences is defined.

Command definitions

Command Dec Hex Description

START_HOST 170 AA Start of frame (from Host)

START_CONTRO LLER 171 AB Start of frame ( fro m µC)

Data frame definition

Within the host/keyboard protocol the following data frames are defined (see

Table 4). The assignment of the LED’s is the same as for the USB protocol and can

be found in

Tabl e 2. The key codes (hex values) are also the same as the Usage ID”s

for the HID keyboard report

Keyboard Interface settings3

For the keyboard interface, different settings are available. Settings can be changed via the

DIP switch (see Figure 1). To change settings, disconnect the keyboard from the host and

set the switches according to table 6. Reconnect the key board to the host for the new

settings to take effect.

screen. The PCB of the keyboards without a touch screen is the same but not all SMD

components shown in the figure are mounted!

Touch Screen Interface4

To operate the touch screen, the analog resistive touch screen controller TSC-30/IC from

DMC is used.

Driver Installation

Before the touch screen can be used the TSC-10/DD driver from DMC must be installed onto

the system. The actual driver can be downloaded from the download section of the DMC

website (http://www.dmccoltd.com/english/). Please follow the instructions of the installation

manual of DMC.

Upon successful installation, the driver can be found in the Windows device manager (“Mice

and other pointing devices”) after plugging the EAO keyboard to the Host (via USB).

Calibration and general Touch Screen settings

To calibrate the touch screen, the UPDD console (installed during driver installation) from

DMC can be used. Please refer to the DMC documentation for calibration and setting details.

The EAO keyboard can save the calibration data. In order to do so (and before calibrating the

touch screen), the appropriate check box must be activated.

Figure 3 - Saving the calibration data

Touch Screen Interface settings

For the touch screen interface, two settings (USB/RS232 communication) are available.

Settings can be changed via the jumpers on the right side of the PCB (see Figure 4). To

change settings, disconnect the keyboard from the Host and set the jumper as desired.

Reconnect the keyboard to the host for new settings to take effect.

Remember to connect the keyboard to the host with the appropriate cable

according to the chosen interface! It is important to change all jumpers according

to the desired setting. Otherwise the keyboard will not operate.

4 These settings are only available for OPAL keyboards with integrated touch screen.

Figure 4 - Interface settings touch controller

By default, the USB interface is activated (see jumper position of Figure 4). To activate the

RS232 interface, change the position of all jumpers so that the middle and the lower pin of

every connector in the blue box are bypassed.
