3. Select the appropriate Baud Rate and Parity settings from the drop-down menus.
4. Click on Initialize to initialize the UDM-RX02.
5. Enter the serial string equivalent to perform the desired control function in the Serial Command text
field (see FIG. 95).
The UDM-0404 supports a predetermined set of actions (commands), against which you can
associate serial strings. For a listing of supported commands, check the Control drop-down menu.
Either enter ASCII text directly into the serial command box or where a HEX code is required.
Precede the double-digit HEX code with a “%” symbol.
The example below (FIG. 96) is from a Panasonic screen where the actual command string requires
a “Start of Text” header (stx), the character command POF (Power Off) and a “End of Text” header
(etx).
Both the headers have therefore been added in HEX and the character string uses ASCII.
6. Once you have finished entering the string you can test that it operates as expected, via the Test
hyperlink. This sends the string typed into the Serial Command text box to the device connected.
Repeat the process as many times as required to test a complete set of controls before saving them to the
protocol library.
Examples of Serial Controls
The video mode select commands (VGA select etc.) are extremely useful commands and enable a serial
string to be associated with a change of input type, allowing a display automatically switched to the
appropriate input port on a change of the video type from the UDM-0404.
See the Ascii / Hex Conversion section on page 91 for details.
