System Control
Audia can be controlled using Telnet via TCP/IP. The same command strings that are used for
RS-232 Control are used for Telnet.
When controlling multiple Audias that are not a part of the same DAP file, each Audia device will
need to be addressed via its own Telnet session from a control system or PC.
Audia supports standard Telnet Echo Negotiation. By default, the Telnet server will echo
characters sent to it, one by one.
To turn echo OFF during a session:
Send byte sequence 0xFF 0xFE 0x01.
Receive 3 byte response from server (0xFF 0xFC 0x01 = echo OFF).
Send desired commands.
To turn echo back ON during a session:
Send byte sequence 0xFF 0xFD 0x01.
Receive 3 byte response from server (0xFF 0xFB 0x01 = echo ON).
Send desired commands.

INC - Tells Audia that a DSP attribute is to be incremented by a specific amount
