Packet Length<br />
Shows the number of bytes in one packet in hexadecimal notation. Indicates the total number of<br />
transmitted bytes from the packet length to the checksum.<br />

Address<br />
A maximum of 16 amplifiers can be connected. This value specifies the address set by the rotary<br />
Switch.<br />
Address=FFh simultaneously specifies all the amplifiers connected to the communication line.<br />
In this case only the amplifier at address 0 will respond.<br />
Command Code<br />
Specifies the command code defined in Chapter 6.<br />
Data <br />
The number of data bytes depends on the command. Sets the defined data for each command.<br />
Data longer than 2 bytes is sent in lower-higher order.<br />
Checksum<br />
The checksum is calculated by adding all bytes except the checksum, and taking the lowest byte.<br />
