Meridian America 562 - Manual

Meridian 562 RS232 Interface.
The RS232 interface for the 562 has been upgraded in Versions 1.7 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 562 will return 4 characters as shown below + 4 ASCII spaces and a carriage
return. Please note that zero characters are actually returned as upper case O.
The following table lists the commands available and shows examples of the messages
returned. These always correspond to the display on the 562.
