2.7 Principles of the TCP interface

• The standard TCP interface port for control commands is 12302.

• Each command must be terminated with a ASCII 0x00, ASCII 0x0D (carriage return) or ASCII 0x0A (line feed).

• The answers are the same as on the SERIAL interface.

2.8 Principles of the TCP Serial Gateway

• Open a TCP connection to the local port (default 12302).

• The serial port parameters can be set in the configuration.

• Each byte transmitted to this TCP port is sent to the serial port.

• Each byte received on the serial port is sent to this TCP port.

• Only one TCP port at once can be used.

• As long as this TCP port is open the serial command interface is disabled.

• If IR functionality is once used (for receiving and/or transmitting), don't use the serial gateway without resetting the device.

2.9 Control, SERIAL, UDP, TCP and CGI WEB interface

Note: Although the Instreamer is an input device, it also has a headphone monitor, hence the commands to control the volume.

Element Description CGI command SERIAL, TCP or UDP command

ANSWERS Standard answer file ack.ack will be sent if nothing else is

specified with the L command. The file nosupport.ack will be

sent on an unknown command.

To change the answer concatenate the command

GETDYNFILE and chose the required answer file.

ex. set volume: v=4&L=volume.ack

see the files in 2.12 Own skins and web interface

MUTE Toggle between mute and volume.

MUTE stores the last volume and resets to this value on turn

on volume. VOLUMEINC, VOLUMEDEC, VOLUME > 0 as well

as FORCEMUTEOFF unmutes the device.

c=8 0x63 0x3D 0x38 0x00 (c=8 )

VOLUMELOCK After this command the volume can’t be changed until you

unlock it.

c=11 0x63 0x3D 0x31 0x31 0x00 (c=11 )

VOLUMEUNLOCK Unlock volume. c=12 0x63 0x3D 0x31 0x32 0x00 (c=12 )

SETASDEFAULT Store current values (volume, volume lock, mute, bass, treble, c=13 0x63 0x3D 0x31 0x33 0x00 (c=13 )
