Meridian Audio 565 Owners manual

Meridian 565 RS232 Interface.

The RS232 interface for the 565 has been upgraded in Versions 2.6 and 3.6 or higher. It can
be operated from any terminal which operates at 9600 baud with 1 start bit, 1 stop bit and no
parity. Commands take the form of 2 ASCII characters, in some cases followed by a signed
argument (‘nn’ below). All characters are echoed by the processor. A carriage return
character will execute the command, and backspace is also implemented. When a command
is executed, the 565 will return 12 characters as shown below.

The following table lists the commands available and shows examples of the messages
returned. These always correspond to the display on the 565.
