Command flow
1) UDP commands can be sent to the AMP’s IP address on port 8711. Alternatively the commands can be sent
to Multicast address 239.254.222.222 (or broadcast) on port 8711.
2) The AMP203 acknowledges the command by returning the same command and a ‘+’ as Argument. (ACK)
In case of a get command the AMP203 will return the current state of the specific get command.
3) The AMP203 sends a Multicast/Broadcast update on port 8712 with the new state. This information is used
for AUDAC Touch 2. This multicast group can be joined by any (user specific) application to receive a constant
flow of the device’s status updates.
Note: When sending commands to the multicast address, all the AMP203 devices with the same device address
(P001 for example) will receive this command and then execute it.

Command overview
Startsymbol | Destination | Source | Command | Argument(s) | Checksum | Stopsymbol
Each command is followed by an ‘x’ character, which represents the number of the slot whereto the
command is sent. If the audio player doesn’t support multiple slots, the number ‘1’ shall always be
used.
Example: Get IP---
ASCII: #|P001|F001|GIP|U|return
HEX: 237C533030317c463030317c4749507c557c72657475726e0a
Notes
• The checksum is CRC-16 excluding the ‘#’. The checksum can always be replaced by
‘U’, which is always accepted.
• Return in ASCII : <CR> <LF> HEX : 0x0D 0x0A (carriage return & line feed)
• Source address has a maximum length of 4 characters and cannot contain ‘|’ or ‘#’
