Configurable HMI Panel Installation Guide and User Manual 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”).

Configurable HMI Panel Installation Guide and User Manual LED interface descriptor: 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.
Configurable HMI Panel Installation Guide and User Manual 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.

Configurable HMI Panel Installation Guide and User Manual 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. Figure 1 - Keyboard interface PLEASE NOTE: The figure shows the PCB of the keyboards with an integrated touch screen.

Configurable HMI Panel Installation Guide and User Manual 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.
Configurable HMI Panel Installation Guide and User Manual 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.
