Sonodyne AM21P - Manual (Page 11)

Third party control is supported via two physical interfaces:
1. RS-232 serial port
2. Ethernet port
The AMD P Series amplifiers provide third party communications when the amplifier is placed in the
power saving mode.

RS-232 Packet Structure
The serial protocol is an ASCII protocol. All characters in the string are ASCII characters.
Binary values ranging between hexadecimal 00 and FF are transmitted as two ASCII characters.
All command strings start with the % character and end with a carriage return (shown as <CR>
in this document) and are equal to the single ASCII value of 13 decimal (0x0D hex).

Ethernet Packet Structure
Ethernet messages are constructed using a simple header and data structure:
<message header><data>
The message header is either a Master (3rd party) or Slave (AMD P series) Header.
Messages from the third party system: <master header><data>
Messages from the AMD P series amplifier: <slave header><data>
