Serial Interface
The Serial Interface translates between an ASCII, RS422 or RS232-
capable terminal or computer and the Performer RS485 bus. The
Serial Interface allows the terminal or computer to masquerade as
a TEN–20, 20–TEN or Performer remote control panel. The
operation of the Serial Interface is invisible to the terminal
operator. The following
Serial Protocol Descriptions provide the
technical information you need to control Performer from
terminals or computers.
