7.12.12. Sending Pronto Hex Codes in Big-endian Format via IR Port
DIFFERENCE:
This feature is available only in UMX-HDMI-140-Plus model.
Command and Response #infra #infrared #ir
ç CALL·/MEDIA/IR/<out>:sendProntoHexBigEndian(<hex_code>)
æ mO·/MEDIA/IR/<out>:sendProntoHexBigEndian
Parameters
Parameter Parameter description
Output port of the
<out>
Infrared interface
Pronto hex format
<hex_code>
code

INFO: This command can send exactly one pronto hex message. The header of the IR code contains the
length of the whole code in hexa format. If the code is deficient or duplicated, it causes syntax error.
For more details about the pronto hex codes see
Example

æ mO /MEDIA/IR/D1:sendProntoHexBigEndian
TIPS AND TRICKS:
Learning raw IR code with a terminal program:
Step 1. Connect to the UMX-HDMI-140-Plus device with a terminal program (see the details in the
for the Terminal Application Usage
Step 2. Push the desired button of the remote control to scan the raw IR code.
Step 3. Remove all the non-hexadecimal characters (e.g. spaces, h characters etc.) from the code.
The pronto hex code which learned by a Lightware device is big-endian format.
Parameter values
Local Infra output: D1; TPS Infra output: D2
Accepts maximum 765 character-long code in hexadecimal
format (0-9; A-F; a-f) without space character in big-endian
system.

7.13. Sending CEC Commands

DIFFERENCE:
INFO:
The hidden first 2 bytes of the CEC command is static, it refers to the logical address of the sender
and the addressee. When the port is input, it is always 04 (from TV to Playback device 1.)., when the port
is output, it is always 40 (from Playback device 1. to TV). Broadcast addressing is also possible (in this
case it is 0F or 4F).
7.13.1. Sending an OSD String
Sending the OSD string consists of two steps. First, set the CEC.OsdString property with the desired text, after
that, call the CEC.send(set_osd) method.
Step 1 – Setting the CEC.OsdString Property
Command and Response
SET·/MEDIA/CEC/<port>.OsdString=<text>
ç
pw·/MEDIA/CEC/<port>.OsdString=<text>
æ
Parameters
<text> Letters (A-Z) and (a-z), hyphen (-), underscore (_), numbers (0-9), and dot (.). Max length: 14
characters.
Example
ç SET /MEDIA/CEC/O1.OsdString=Lightware
æ pw /MEDIA/CEC/O1.OsdString=Lightware
Step 2 – Call the CEC.send(set_osd) method
Command and Response
ç CALL·/MEDIA/CEC/<port>:send(set_osd)
æ mO /MEDIA/CEC/<port>:send
Instructions
Example
ç CALL /MEDIA/CEC/I1:send(set_osd)
æ mO /MEDIA/CEC/I1:send
This feature is available only in UMX-HDMI-140-Plus model.
