RS232/UDP CONTROL COMMANDS
GENERAL
The UHD Player can be controlled remotely by sending the ASCII commands (listed
Below) within a UDP packet sent to the default UDP port 4950 (or the one you entered in the
or via the player’s
RS232 interface.
PLEASE NOTE:
For all serial and UDP commands, the command string must be terminated with carriage return
and line feed (CR LF or 0x0D 0x0A)!
When sending commands with arguments, do not put any space character between the command
and the argument.
Command:
<command><argument> [CR LF]
Example:
Setting the volume to the value “8” using the command “VOLUME=”
Command:
VOLUME=8 [CR LF]
When the UHD Player receives a command string and determines that it is valid, it performs the
command and sends a response to the host device (when using UDP: on the same port).
Command:
<command> [CR LF]
Response:
Received:<command> [CR LF]
Example
Command:
PAUSE [CR LF]
Response:
Received:PAUSE [CR LF]
When the UHD Player is unable to perform the command because the command is invalid or
contains invalid parameters, the player returns nothing.
When the UHD Player receives a request string (characterized by an
ending with a “?”), it will return
the corresponding answer.
Example
Request:
MUTE? [CR LF]
Response:
MUTE=0
