UDM-0404 Endeleo Multi-Format Distribution Hub
Testing Serial Control Commands
Device serial codes can be tested via options in the Status page, before they are added to the protocol
library.
The UDM-RX02 can store approximately eight serial commands per device, depending on the length of
the serial string.
1. On the Status page. click on a Port hyperlink to access the Port Configuration options.
2. In the Protocol drop-down menu, select Serial to enable the Serial-specific configuration options
shown in FIG. 97.
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. 97).
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. 98) 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.
Serial commands are stored in the UDM-RX02, and care should be taken to keep any
serially programmed units associated with the correct display device type.
